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.

Add Required Validator on Dynamic Asp:net Table

I want to add some Required Validator on Controls(Textbox as example) in a dynamic asp:table.
Code:
foreach (KeyValuePair<string, string> o in Collection)
{
TableRow Row = new TableRow();
TableCell valueCell = new TableCell();
TableCell Cell = new TableCell();
TextBox txtBox = new TextBox();
TextBox txtBox1 = new TextBox();
txtBox1.ID = o.Key + o.Value;
if (o.Value.Contains("Mandatory"))
{
RequiredFieldValidator req = new RequiredFieldValidator();
req.ErrorMessage = "Required";
req.BorderColor = System.Drawing.Color.Red;
req.ControlToValidate = txtBox1.ID;
req.Enabled = true;
req.Display = ValidatorDisplay.Dynamic;
Cell.Controls.Add(req);
}
valueCell.Controls.Add(txtBox1);
Row.Cells.Add(valueCell);
Row.Cells.Add(Cell);
table.Rows.Add(Row);
}
But i am getting this error:
" System.Web.UnhandledException in System.web.dll"
on the line Row.Cells.Add(Cell);
Can you help me ?

I fix the problem with a Panel which contains the Texbox and the RequireValidatorField.
Panel p = new Panel();
p.Controls.Add(txtBox1);
p.Controls.Add(req);
valueCell.Controls.Add(p);

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();

Ratingcontrol gives Javascript:void(0)

After some minor difficulties with my basic test rating control not working because of the missing inline CSS stylesheet, I am trying to dynamically add a bunch of rating controls in a updatepanel when I click on a button in a different updatepanel. (These panels are both in a parent updatepanel, I have defined the triggers and set the updatemode to conditional). Anyways, when I click the button, he updates the updatepanel with the rating controls, but when I hover over them, he always displays 0 (the current rating), and does not change the rating control star image (filledStarRating). The code relevant to my problem (two methods):

I'm also adding the link to an image that shows my problem, so that you can see it for yourself:

We had the same issue recently and the problem was that the latest version of the AjaxControltoolkit seems to require a ToolkitScriptManager instead of the normal ScriptManager.
So just try changing your
asp:ScriptManager tag to
asp:ToolKitScriptManager or
ajax:ToolKitScriptManager
or whatever your namespace is.

Problems in getting values from dynamically added controls in C#

I have to dynamically create controls and add them to a table. In a button click I need to find the value entered for that control. The control ids are also dynamic. Below is the code I tried.
private void createUdfControls()

the problem is that i m getting the rowcount=0 of the table tblUdf inside which i added the table rows and controls inside the table cells.
Any help how to get the control values of the dynamically added controls.
Thankx.

You need to make sure that you add the controls again on postback before you read back the values.

To elaborate on Ben's answer, you need to override the CreateChildControls method and create your controls there. The docs for this method provide a handy example of doing what you're doing:
