How to save multiple dynamic textboxes value into SQL Server database

I want to add some panel dynamically into a single panel on a button click. And each dynamic panel consist of multiple text box in horizontally. And then I want to save those text box value into the database.
I have completed to add dynamic panel and horizontal multiple text box into that panel. But couldn't know how to save them into database.
Here is the code I have written:
int v = 0;
TextBox txt1;
TextBox txt2;
TextBox txt3;
TextBox txt4;
TextBox txt5;
ComboBox cmb4;
public void tett()
{
v = 0;
Panel whitePanel = new Panel();
whitePanel.Name = "wt";
// Quantity
txt1 = new TextBox();
txt1.Location = new Point(192, 38);
txt1.Size = new Size(120, 24);
txt1.Name = "text" + v ;
txt1.Text = txt1.Name;
v = v + 1;
// Total Price
txt2 = new TextBox();
txt2.Location = new Point(566, 38);
txt2.Size = new Size(120, 24);
txt2.Name = "text" + v;
txt2.Text = txt2.Name;
txt2.TextChanged += Txt2_TextChanged;
v = v + 1;
// Unit Price
txt3 = new TextBox();
txt3.Location = new Point(753, 38);
txt3.Size = new Size(120, 24);
txt3.Name = "text" + v;
txt3.Text = txt3.Name;
v = v + 1;
// Sell Price
txt4 = new TextBox();
txt4.Location = new Point(903, 38);
txt4.Size = new Size(120, 24);
txt4.Name = "text" + v;
txt4.Text = txt4.Name;
v = v + 1;
// Product
txt5 = new TextBox();
txt5.Location = new Point(5, 38);
txt5.Size = new Size(120, 24);
txt5.Name = "text" + v;
txt5.Text = txt5.Name;
txt5.AutoCompleteSource = AutoCompleteSource.CustomSource;
txt5.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
txt5.MouseClick += textBox5_MouseClick;
Label lbl3 = new Label();
Label lbl4 = new Label();
Label lbl5 = new Label();
Label lbl6 = new Label();
Label lbl7 = new Label();
Label lbl8 = new Label();
lbl3.Location = new Point(5, 15);
lbl3.Text = "Product";
lbl4.Location = new Point(192, 15);
lbl4.Text = "Quantity";
lbl5.Location = new Point(379, 15);
lbl5.Text = "Unit";
lbl6.Location = new Point(566, 15);
lbl6.Text = "Total Price";
lbl7.Location = new Point(753, 15);
lbl7.Text = "Unit Purchase Price";
lbl8.Location = new Point(903, 15);
lbl8.Text = "Unit Sell Price";
cmb4 = new ComboBox();
// Unit
cmb4.Location = new Point(379, 38);
cmb4.Size = new Size(120, 24);
whitePanel.BackColor = ColorTranslator.FromHtml("#ECF0F5");
whitePanel.Location = new Point(1, a * 10);
whitePanel.Size = new Size(1330, 60);
var _button = new Button();
_button.Text = "Dispose";
_button.Name = "DisposeButton";
_button.Location = new Point(1053, 38);
_button.MouseClick += _button_MouseClick;
whitePanel.Controls.Add(_button);
a = a + 5;
v = v + 1;
whitePanel.Controls.Add(lbl3);
whitePanel.Controls.Add(lbl4);
whitePanel.Controls.Add(lbl5);
whitePanel.Controls.Add(lbl6);
whitePanel.Controls.Add(lbl7);
whitePanel.Controls.Add(lbl8);
whitePanel.Controls.Add(txt1);
whitePanel.Controls.Add(txt2);
whitePanel.Controls.Add(txt3);
whitePanel.Controls.Add(txt4);
whitePanel.Controls.Add(txt5);
whitePanel.Controls.Add(cmb4);
panel1.Controls.Add(whitePanel);
}
In this way the output is like this..... By click on the New Purchase this multiple panel with text box will appear:
Multiple dynamic panel with multiple text box
Here the way of setting text box name is not seems better way to me. I want to use an array for set the name of text boxes.
And after all I want to save those values into db by click on the save button using an array or for loop... But I don't know how to define it..
Can anyone please help me?
And thanks in advance

With this approach, a gridview is usefull.
But within your question, the approach is;
int rowNum = 1;
public void tett() {
Control[] controlsToAdd = { new TextBox(), new TextBox(), new ComboBox(), new TextBox(), new TextBox(), new TextBox(), new Button() };
string[] labels = { "Product", "Quantity", "Unit", "Total Price", "Unit Purchase", "Unit Sell Price" };
Panel whitePanel = new Panel() {
Name = "wt",
Dock = DockStyle.Top,
AutoSizeMode = AutoSizeMode.GrowAndShrink,
AutoSize = true,
Padding = new Padding(0, 5, 0, 5),
BackColor = ColorTranslator.FromHtml("#ECF0F5")
};
int controlX = 5, controlY = 15, controlDistance = 15;
for (int i = 0; i < controlsToAdd.Length; i++) {
if (labels.Length > i) {
var label = new Label() {
Text = labels[i],
Location = new Point(controlX, controlY)
};
whitePanel.Controls.Add(label);
}
var control = controlsToAdd[i];
control.Location = new Point(controlX, controlY + 23);
control.Size = new Size(120, 24);
if (control is Button) {
control.Name = "disposeButton" + i;
control.Text = "Dispose";
control.Click += _button_MouseClick;
} else {
if(i == 0) { //if it is the Product textbox
((TextBox)control).AutoCompleteSource = AutoCompleteSource.CustomSource;
((TextBox)control).AutoCompleteMode = AutoCompleteMode.SuggestAppend;
//control.MouseClick += textBox5_MouseClick;
}
control.Name = "Text" + i;
control.Text = "Row" + rowNum + " Text" + i;
}
whitePanel.Controls.Add(control);
controlX += 120 + controlDistance;
}
panel1.Controls.Add(whitePanel);
whitePanel.BringToFront();
rowNum++;
}
private void _button_MouseClick(object sender, EventArgs e) {
//button does its job here
((Button)sender).Parent.Parent.Controls.Remove(((Button)sender).Parent);
}
public SqlConnection Conn { get; }
void save() {
foreach(Panel whitePanel in panel1.Controls) {
var sqlString = "INSERT INTO products(productField, quantityField, unitField, priceField, purchaseField, sellPriceField) VALUES (";
foreach (Control control in whitePanel.Controls) {
if(!(control is Label) && !(control is Button)) { //So, textbox or combobox remained
sqlString += "'"+ control.Text +"', ";
}
}
sqlString = sqlString.Substring(0, sqlString.Length - 2) + ")";
//Assume you have previous construction of SqlConnection as name "Conn"
if (Conn != null) {
if (Conn.State != ConnectionState.Open) Conn.Open();
using (var cmd = new SqlCommand(sqlString, Conn)) {
cmd.ExecuteNonQuery();
}
Conn.Close();
}
Console.WriteLine(sqlString);
}
}
I have tested and works as expected. If it is not suit your needs, make me know.

Not able to add multiple DataGridViewButtonColumn at runtime

I'm calling a function from another class to a form to load datagridView. when i add only one dataGirdViewButtonColumn its works but when i add two the second one is not added.Another problem i have found is the button is added to empty row..
Function
public void LoadDataGridrcv(DataTable d, DataGridView dg)
{
DataGridViewButtonColumn btn = new DataGridViewButtonColumn();
DataGridViewButtonColumn btn1 = new DataGridViewButtonColumn();
if (dg.InvokeRequired)
{
dg.BeginInvoke((MethodInvoker)delegate()
{
dg.Rows.Clear();
dg.ColumnCount = 7;
dg.Columns[0].Name = "Order No.";
dg.Columns[0].Width = 110;
dg.Columns[1].Name = "Order Date";
dg.Columns[1].Width = 100;
dg.Columns[2].Name = "Excepted rcv date";
dg.Columns[2].Width = 100;
dg.Columns[3].Name = "Supplier";
dg.Columns[3].Width = 150;
dg.Columns[4].Name = "Total Items";
dg.Columns[4].Width = 80;
dg.Columns[5].Name = "Total";
dg.Columns[5].Width = 80;
dg.Columns[6].Name = "Status";
dg.Columns[6].Width = 100;
dg.Columns.Add(btn);
btn.HeaderText = "Click to view";
btn.Text = "View";
btn.Name = "btn";
btn.UseColumnTextForButtonValue = true;
btn1.HeaderText = "Click to recieve";
btn1.Text = "Recieve";
btn1.Name = "btn1";
btn1.UseColumnTextForButtonValue = true;
});
foreach (DataRow row in d.Rows)
{
if (dg.InvokeRequired)
{
dg.BeginInvoke((MethodInvoker)delegate() { dg.Rows.Add(row[0].ToString(), row[1].ToString(), row[2].ToString(), row[3].ToString(), row[4].ToString(), row[5].ToString(), row[6].ToString()); });
}
Thread.Sleep(100);
}
}
}
Usage
reatail r = new reatail();
t = new Thread(() => r.LoadDataGridrcv(r.loadAllOrder(), dataGridView1));
t.Start();

By a RadGridView, how can I get to show detail information?

I have created a hierarchical relationship in a RadGridView. But the relationship doesn't work. I can't show the detail information. What do I do wrong?
If I generated automatically all relationships works fine. But I need just one field of one table as detail info.
Further: I use VS2013 Prof., WinForms as UI and LINQ to SQL as datasource.
The source code is:
private void OpenConfigurations()
{
bsConfigurations.DataSource = Db.Configurations.Where(c => c.Active == true && c.CompanyId == CurrentCompany.CompanyId).Select(c => c).OrderBy(c => c.Name);
bsConfigurationContracts.DataSource = Db.ConfigurationContracts.Where(c => c.Contract.InsurranceId == CurrentCompany.CompanyId).Select(c =>
c).OrderBy(c => c.Contract.Name);
GridViewRelation gvrConfigurations = new GridViewRelation();
gvrConfigurations.ChildColumnNames.Add("ConfigurationId");
gvrConfigurations.ChildTemplate = this.gridViewTemplate1;
gvrConfigurations.ParentColumnNames.Add("ConfigurationId");
gvrConfigurations.ParentTemplate = this.gvConfiguration.MasterTemplate;
gvConfiguration.Relations.Add(gvrConfigurations);
}
In the designer:
this.gridViewTemplate1.AllowAddNewRow = false;
gridViewTextBoxColumn1.EnableExpressionEditor = false;
gridViewTextBoxColumn1.FieldName = "Contract.Name";
gridViewTextBoxColumn1.HeaderText = "Name";
gridViewTextBoxColumn1.Name = "colName";
gridViewTextBoxColumn1.Width = 250;
gridViewTextBoxColumn2.EnableExpressionEditor = false;
gridViewTextBoxColumn2.FieldName = "ConfigurationId";
gridViewTextBoxColumn2.HeaderText = "ConfigurationId";
gridViewTextBoxColumn2.IsVisible = false;
gridViewTextBoxColumn2.Name = "colConfigurationId";
this.gridViewTemplate1.Columns.AddRange(new Telerik.WinControls.UI.GridViewDataColumn[] { gridViewTextBoxColumn1, gridViewTextBoxColumn2 });
this.gridViewTemplate1.DataSource = this.bsConfigurationContracts;
//
// gvConfiguration
//
this.gvConfiguration.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(233)))), ((int)(((byte)(240)))), ((int)(((byte)(249)))));
this.gvConfiguration.Cursor = System.Windows.Forms.Cursors.Default;
this.gvConfiguration.Dock = System.Windows.Forms.DockStyle.Fill;
this.gvConfiguration.Font = new System.Drawing.Font("Segoe UI", 8.25F);
this.gvConfiguration.ForeColor = System.Drawing.Color.Black;
this.gvConfiguration.ImeMode = System.Windows.Forms.ImeMode.NoControl;
this.gvConfiguration.Location = new System.Drawing.Point(0, 30);
//
//
//
this.gvConfiguration.MasterTemplate.AllowAddNewRow = false;
this.gvConfiguration.MasterTemplate.AutoGenerateColumns = false;
gridViewTextBoxColumn3.EnableExpressionEditor = false;
gridViewTextBoxColumn3.FieldName = "Name";
gridViewTextBoxColumn3.HeaderText = "Name";
gridViewTextBoxColumn3.Name = "colName";
gridViewTextBoxColumn3.SortOrder = Telerik.WinControls.UI.RadSortOrder.Ascending;
gridViewTextBoxColumn3.Width = 250;
gridViewTextBoxColumn4.EnableExpressionEditor = false;
gridViewTextBoxColumn4.FieldName = "ConfigurationId";
gridViewTextBoxColumn4.HeaderText = "ConfigurationId";
gridViewTextBoxColumn4.IsVisible = false;
gridViewTextBoxColumn4.Name = "colConfigurationId";
this.gvConfiguration.MasterTemplate.Columns.AddRange(new Telerik.WinControls.UI.GridViewDataColumn[] { gridViewTextBoxColumn3, gridViewTextBoxColumn4 });
this.gvConfiguration.MasterTemplate.DataSource = this.bsConfigurations;
sortDescriptor1.PropertyName = "colName";
this.gvConfiguration.MasterTemplate.SortDescriptors.AddRange(new Telerik.WinControls.Data.SortDescriptor[] { sortDescriptor1 });
this.gvConfiguration.MasterTemplate.Templates.AddRange(new Telerik.WinControls.UI.GridViewTemplate[] { this.gridViewTemplate1 });
this.gvConfiguration.Name = "gvConfiguration";
this.gvConfiguration.RightToLeft = System.Windows.Forms.RightToLeft.No;
this.gvConfiguration.ShowGroupPanel = false;
this.gvConfiguration.Size = new System.Drawing.Size(1098, 72);
this.gvConfiguration.TabIndex = 4;
this.gvConfiguration.Text = "radGridView1";
this.gvConfiguration.CellDoubleClick += new Telerik.WinControls.UI.GridViewCellEventHandler(this.gvConfiguration_CellDoubleClick);

The solution is in the relation you have to add the column name in stead of the field name.
So this is the right code:
GridViewRelation gvrConfigurations = new GridViewRelation();
gvrConfigurations.ChildColumnNames.Add("colConfigurationId");
gvrConfigurations.ChildTemplate = this.gridViewTemplate1;
gvrConfigurations.ParentColumnNames.Add("colConfigurationId");
gvrConfigurations.ParentTemplate = this.gvConfiguration.MasterTemplate;
gvConfiguration.Relations.Add(gvrConfigurations);

Not getting BarChart in Winform Application

I am trying to show a dynamic barchart from database in winform application but it is not coming and giving me Argument out of Exception error at var p2 = series.Points[arrlocationSTD]; when arrlocationSTD=1. Here is my code in c#..
void LoadBarChart(string qurystring)
{
if (calltype.Equals("TRANSFERED"))
{
totalTransfered = dr["SummaryOfCalls"].ToString();
intTRANSFERED = int.Parse(totalTransfered, CultureInfo.InvariantCulture);
if (i == 0)
{
arrlocationTransferred = i;
series.Points.Add(intTRANSFERED);
var p7 = series.Points[arrlocationTransferred];
p7.Color = Color.Yellow;
p7.AxisLabel = "TRANSFERED";
p7.LegendText = "TRANSFERED";
p7.Label = totalTransfered;
i++;
}
else
{
arrlocationTransferred = i;
series.Points.Add(intTRANSFERED);
var p7 = series.Points[arrlocationTransferred];
p7.Color = Color.Yellow;
p7.AxisLabel = "TRANSFERED";
p7.LegendText = "TRANSFERED";
p7.Label = totalTransfered;
}
}
}
barChart.Invalidate();
pnlBar.Controls.Add(barChart);
}
Please help me to resolve this.
Thanks in advance..

You'll need to add your additional processing, but the following might help.
I'd strongly recommend that you get the chart showing your data correctly before you start changing colour properties and such.
void LoadBarChart(string qurystring)
{
String conn = Strings.ConnectionString; // You fill this in.
Dictionary<String,int> callSummariesByTypeOfCall =
new Dictionary<String,int>();
MySqlConnection con = new MySqlConnection(conn);
MySqlCommand comm = new MySqlCommand(qurystring, con);
con.Open();
MySqlDataReader dr = comm.ExecuteReader();
// Get the data into a dictionary
while (dr.Read())
{
String calltype = dr["TypeOfCall"].ToString();
int summary = int.Parse(dr["Calls"].ToString(), CultureInfo.InvariantCulture);
callSummariesByTypeOfCall[calltype] = summary;
}
// Do any other processing you need here
// Bind the data onto the Series
Series series = new Series
{
Name = "series2",
IsVisibleInLegend = false,
ChartType = SeriesChartType.Column
};
series.Points.DataBindXY(
callSummariesByTypeOfCall.Keys,
callSummariesByTypeOfCall.Values);
barChart.Series.Add(series);
barChart.Invalidate();
pnlBar.Controls.Add(barChart);
}

EWS - How to search for items [message] between dates?

I am trying to search for message items between two dates from the inbox folder.
I use the following restrictionType but it throws this error:

What am I doing wrong?
There is some messages between the mentionned dates ;-)

I found the answer on my own after a long search about date format.
The restrictions has to be defined as this:
// greater or equal to
string dateStart = DateTime.Today.add(-6d);
string dateEnd = DateTime.Today.Add(1d);
PathToUnindexedFieldType dateSentPath = new PathToUnindexedFieldType();
dateSentPath.FieldURI = UnindexedFieldURIType.itemDateTimeSent;
IsGreaterThanOrEqualToType IsGreaterThanOrEqual = new IsGreaterThanOrEqualToType();
IsGreaterThanOrEqual.Item = dateSentPath;
FieldURIOrConstantType dateConstant = new FieldURIOrConstantType();
ConstantValueType dateConstantValue = new ConstantValueType();
dateConstantValue.Value = string.Format("{0}-{1}-{2}T00:00:00Z", dateStart.Year.ToString(), dateStart.Month.ToString(), dateStart.Day.ToString());
dateConstant.Item = dateConstantValue;
IsGreaterThanOrEqual.FieldURIOrConstant = dateConstant;
// less than or equal to
PathToUnindexedFieldType dateSentPath1 = new PathToUnindexedFieldType();
dateSentPath1.FieldURI = UnindexedFieldURIType.itemDateTimeSent;
IsLessThanOrEqualToType lessThanOrEqualTo = new IsLessThanOrEqualToType();
lessThanOrEqualTo.Item = dateSentPath1;
FieldURIOrConstantType dateConstant1 = new FieldURIOrConstantType();
ConstantValueType dateConstantValue1 = new ConstantValueType();
dateConstantValue1.Value = string.Format("{0}-{1}-{2}T00:00:00Z", dateEnd.Year.ToString(), dateEnd.Month.ToString(), dateEnd.Day.ToString());
dateConstant1.Item = dateConstantValue1;
lessThanOrEqualTo.FieldURIOrConstant = dateConstant1;
RestrictionType restriction = new RestrictionType();
AndType andType = new AndType();
andType.Items = new SearchExpressionType[] { lessThanOrEqualTo, IsGreaterThanOrEqual };
restriction.Item = andType;
findItemRequest.Restriction = restriction;
Hope this help someone some day ;-)

In case anyone stumbles upon this in the future, EWS has gotten even more strict about date formatting. The accepted answer formatting works for 2 digit months, but it does not for single digit months.
The formatting that works in all cases is:
DateTime.Today.AddDays(15).ToString("yyyy-MM-ddThh:mm:ssZ")

The restriction also works using the "Sortable date/time pattern".
Datetime.Now.ToString("s")
