Please help me in the backend i have given the code as
protected void BindGridviewData()
{
DataTable dt = new DataTable();
string strQuery = "SELECT * from Master_Worksheets where MGR_CODE ='" + lblUsername.Text + "' AND (MGR_STATUS='New' OR MGR_STATUS='Decline')";
using (SqlConnection con = new SqlConnection(strConnString))
{
SqlCommand cmd = new SqlCommand(strQuery);
using (SqlDataAdapter sda = new SqlDataAdapter())
{
cmd.Connection = con;
con.Open();
sda.SelectCommand = cmd;
sda.Fill(dt);
}
}
gvconverted.DataSource = ConvertColumnsAsRows(dt);
gvconverted.DataBind();
gvconverted.HeaderRow.Visible = false;
}
public DataTable ConvertColumnsAsRows(DataTable dt)
{
DataTable dtnew = new DataTable();
//Convert all the rows to columns
for (int i = 0; i <= dt.Rows.Count; i++)
{
dtnew.Columns.Add(Convert.ToString(i));
}
DataRow dr;
// Convert All the Columns to Rows
for (int j = 0; j < dt.Columns.Count; j++)
{
dr = dtnew.NewRow();
dr[0] = dt.Columns[j].ToString();
for (int k = 1; k <= dt.Rows.Count; k++)
dr[k] = dt.Rows[k - 1][j];
dtnew.Rows.Add(dr);
}
return dtnew;
}

I guess you need to swap the rows and columns of Datatable.
If that is what you need then please refer this link. It will help you

How to Add the DropDownList in GridView with item selection and textboxes

I am new in asp.net development
I have created a project its working fine but i want to select the Designation from drop down but want to store the id of the designation instead of the designation
Here is my Asp.net Code for my Project
protected void BindData()
{
DataSet ds = new DataSet();
conn.Open();
string cmdstr = "Select * from EmployeeDetails";
SqlCommand cmd = new SqlCommand(cmdstr, conn);
SqlDataAdapter adp = new SqlDataAdapter(cmd);
adp.Fill(ds);
cmd.ExecuteNonQuery();
conn.Close();
GridView1.DataSource = ds;
GridView1.DataBind();
}
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName.Equals("ADD"))
{
TextBox txtAddEmpID = (TextBox)GridView1.FooterRow.FindControl("txtAddEmpID");
TextBox txtAddName = (TextBox)GridView1.FooterRow.FindControl("txtAddName");
DropDownList ddlDesignation = (DropDownList)GridView1.FooterRow.FindControl("ddlDesignation");
TextBox txtAddCity = (TextBox)GridView1.FooterRow.FindControl("txtAddCity");
TextBox txtAddCountry = (TextBox)GridView1.FooterRow.FindControl("txtAddCountry");
conn.Open();
string cmdstr = "insert into EmployeeDetails(empid,name,designation,city,country) values(#empid,#name,#designation,#city,#country)";
SqlCommand cmd = new SqlCommand(cmdstr, conn);
cmd.Parameters.AddWithValue("#empid", txtAddEmpID.Text);
cmd.Parameters.AddWithValue("#name", txtAddName.Text);
cmd.Parameters.AddWithValue("#designation", ddlDesignation.SelectedItem.ToString());
cmd.Parameters.AddWithValue("#city", txtAddCity.Text);
cmd.Parameters.AddWithValue("#country", txtAddCountry.Text);
cmd.ExecuteNonQuery();
conn.Close();
BindData();
}
}
protected void GridView1_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Footer)
{
DropDownList ddlDesignation = (DropDownList)e.Row.FindControl("ddlDesignation");
DataSet ds = new DataSet();
conn.Open();
string cmdstr = "Select * from Designation";
SqlCommand cmd = new SqlCommand(cmdstr, conn);
SqlDataAdapter adp = new SqlDataAdapter(cmd);
adp.Fill(ds);
ddlDesignation.DataSource = ds.Tables[0];
ddlDesignation.DataTextField = "designation";
ddlDesignation.DataValueField = "id";
ddlDesignation.DataBind();
ddlDesignation.Items.Insert(0, new ListItem("--Select--", "0"));
this.TextBox1.Text = ddlDesignation.SelectedItem.ToString();
conn.Close();
}
}
and also this is my aspx.cs code for project
<asp:GridView ID="GridView1" runat="server" Width="100%" AutoGenerateColumns="false" ShowFooter="true" OnRowCommand="GridView1_RowCommand" OnRowDataBound="GridView1_OnRowDataBound"

</FooterTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

You need to get value from SelectedValue property of dropdwon.
cmd.Parameters.AddWithValue("#designation", ddlDesignation.SelectedValue.ToString());

Did you try
var e = document.getElementById("ddlDesignation");
var strDesigId = e.options[e.selectedIndex].value;
document.getElementById("TextBox1").value = strDesigId;

insert date in wrong way

you just need to add Convert.ToDateTime() , then your query'll definately work.
but, your doing it in a wrong way.
use Parameterized Query,
A parameterized query is a query in which placeholders are used for
parameters and the parameter values are supplied at execution time.
The most important reason to use parameterized queries is to avoid SQL
injection attacks
In your case, you need to change the insert query:
string query = "insert into tblusage(codeCust,codeVendor,codeService,codeRegion,Usages,isSecure,dateStart,dateEnd) values (" + cc + "," + cv + "," + cs + "," + cr + "," + usag + "," + isecure + "," + Convert.ToDateTime(ds) + "," + Convert.ToDateTime(de) + ") ";
Or, You can change the ds and dt variable datatype
CultureInfo provider = CultureInfo.InvariantCulture;
string format="dd/mm/yyyy";//define your datetime format here
DateTime ds=DateTime.ParseExact(textbox1.Text, format, provider);
DateTime de=DateTime.ParseExact(textbox2.Text, format, provider);
and then pass it to the query,like
string query = "insert into tblusage(codeCust,codeVendor,codeService,codeRegion,Usages,isSecure,dateStart,dateEnd) values (" + cc + "," + cv + "," + cs + "," + cr + "," + usag + "," + isecure + "," +ds + "," + de + ") ";
Edit 2:
private void add(int cc, int cv, int cs, int cr,int usag,int isecure, string ds, string de)
{
using (MySqlConnection cn = new MySqlConnection(connectionstring))
{
string query = "insert into tblusage(codeCust,codeVendor,codeService,codeRegion,Usages,isSecure,dateStart,dateEnd) values (#cc,#cv,#cs,#cr,#usag,#isecure,#ds,#de) ";
MySqlCommand cmd = new MySqlCommand(query, cn);
cmd .Parameters.Add("#cc",MySqlDbType.Int).Value=cc;
cmd .Parameters.Add("#cv",MySqlDbType.Int).Value=cv;
cmd .Parameters.Add("#cs",MySqlDbType.Int).Value=cs;
cmd .Parameters.Add("#cr",MySqlDbType.Int).Value=cr;
cmd .Parameters.Add("#usag",MySqlDbType.Int).Value=usag;
cmd .Parameters.Add("#isecure",MySqlDbType.Int).Value=isecure;
cmd .Parameters.Add("#ds",MySqlDbType.Date).Value=ds;
cmd .Parameters.Add("#de",MySqlDbType.Date).Value=de;
cn.Open();
cmd.ExecuteNonQuery();
}
}

Please consider using parametric queries & Convert.toDateTime().
private void add(int cc, int cv, int cs, int cr,int usag,int isecure, string ds, string de)
{
using (MySqlConnection cn = new MySqlConnection(connectionstring))
{
using (var sqlcmd = new SqlCommand())
{
sqlcmd.Connection = cn;
sqlcmd.CommandText = "insert into tblusage(codeCust,codeVendor,codeService,codeRegion,Usages,isSecure,dateStart,dateEnd) values (#codeCust,
#codeVendor, #codeService, #codeRegion, #Usages, #isSecure, #dateStart, #dateEnd)")
sqlcmd.Parameters.AddWithValue("#codeCust", cc);
sqlcmd.Parameters.AddWithValue("#codeVendor", cv);
sqlcmd.Parameters.AddWithValue("#codeService", cs);
sqlcmd.Parameters.AddWithValue("#codeRegion", cr);
sqlcmd.Parameters.AddWithValue("#Usages", usag);
sqlcmd.Parameters.AddWithValue("#isSecure", isecure);
sqlcmd.Parameters.AddWithValue("#dateStart", Convert.ToDateTime(ds));
sqlcmd.Parameters.AddWithValue("#dateEnd", Convert.ToDateTime(de));
cn.open();
sqlcmd.ExecuteNonQuery();
}
}
}

You have to specify date format.
Sample code:
str_to_date(de,"%d/%m/%Y")
str_to_date is mysql function. Kindly refer MySQL documentation.
https://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html

Thank you in Advance

You can inject the needed separator rows by adding “separator records” to the data source before binding it to the GridView.
Here is an example I came across:
protected override void Render(HtmlTextWriter writer)
{
string lastSubCategory = String.Empty;
Table gridTable = (Table)gvProducts.Controls[0];
foreach (GridViewRow gvr in gvProducts.Rows)
{
HiddenField hfSubCategory = gvr.FindControl("hfSubCategory") as
HiddenField;
string currSubCategory = hfSubCategory.Value;
if (lastSubCategory.CompareTo(currSubCategory) != 0)
{
int rowIndex = gridTable.Rows.GetRowIndex(gvr);
// Add new group header row
GridViewRow headerRow = new GridViewRow(rowIndex, rowIndex,
DataControlRowType.DataRow, DataControlRowState.Normal);
TableCell headerCell = new TableCell();
headerCell.ColumnSpan = gvProducts.Columns.Count;
headerCell.Text = string.Format("{0}:{1}", "SubCategory",
currSubCategory);
headerCell.CssClass = "GroupHeaderRowStyle";
// Add header Cell to header Row, and header Row to gridTable
headerRow.Cells.Add(headerCell);
gridTable.Controls.AddAt(rowIndex, headerRow);
// Update lastValue
lastSubCategory = currSubCategory;
}
}
base.Render(writer);
}

On deleting the Row of GridView not working properly

Whenever I delete a row from the gridview which I select to delete, the row above to the selected row gets deleted. Dont know why. Please see my code for deleting.

Code behind for your ref:-
protected void grdPostData_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
bool IsDeleted = false;
int Id = Convert.ToInt32(grdPostData.DataKeys[e.RowIndex].Value.ToString());
using (SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["DefaultCSRConnection"].ConnectionString))
{
using (SqlCommand cmd = new SqlCommand())
{
cmd.CommandText = "DELETE FROM tbl_Post WHERE Id=#Id";
cmd.Parameters.AddWithValue("#Id", Id);
cmd.Connection = conn;
conn.Open();
IsDeleted = cmd.ExecuteNonQuery() > 0;
conn.Close();
}
}
if (IsDeleted)
{
ScriptManager.RegisterStartupScript(this, this.GetType(), "alert", "alert('Page Succesfully deleted');window.location ='csrposts.aspx';", true);
grdPostData.DataBind();
}
else
{
Response.Write("Some error");
}
}
Please let me know where I am going wrong. I tried debugging the code and the Id was taking 0.
Gridview bindinf Code:-
public void BindGrid()
{
string strQuery = "Select Id, title, description, Active from tbl_Post Order by ID desc";
SqlCommand cmd = new SqlCommand(strQuery);
DataTable dt = GetData(cmd);
grdPostData.DataSource = dt;
grdPostData.DataBind();
}
private DataTable GetData(SqlCommand cmd)
{
DataTable dt = new DataTable();
SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["DefaultCSRConnection"].ConnectionString);
SqlDataAdapter sda = new SqlDataAdapter();
cmd.CommandType = CommandType.Text;
cmd.Connection = conn;
try
{
conn.Open();
sda.SelectCommand = cmd;
sda.Fill(dt);
return dt;
}
catch (Exception ex)
{
throw ex;
}
finally
{
conn.Close();
sda.Dispose();
conn.Dispose();
}
}

Updated Solution. Completely Working. I am Creating those textboxes in DataBound and theirs a if condition that checks whether Gridview is Empty or Not.
If Gridview is empty then HeaderRow wont be created so that Gridview and Page is able to display else HeaderRow will be Displayed.
Hope this Works for You.

Row Deleting Code is Same.

Your code looks good. Hope its not a problem from database. Try this
Add this to Gridview
OnRowCommand="GridView_RowCommand"
CodeBehing:-
protected void GridView_RowCommand(object sender, GridViewCommandEventArgs e)
{
if(e.CommandName=="Delete")
{
// Get the value of command argument
int Id= convert.ToInt32(e.CommandArgument);
// Do whatever operation you want.
}
}
Alternatively:-
Add onclick event on your imagebutton of delete and try this
protected void ImageButton_Click(object sender, EventArgs e)
{
ImageButton btn = sender as ImageButton;
GridViewRow gRow = (GridViewRow)btn.NamingContainer;
int id =Convert.ToInt32((gRow.FindControl("lblId") as Label).Text);
}
Update:-
Change your itemtemplate to this
<asp:TemplateField HeaderText="Post Category" ItemStyle-Width="50">
<ItemTemplate>
<asp:DropDownList ID="ddlPostCategory" AppendDataBoundItems="true" runat="server"
AutoPostBack="false">
<%-- <asp:ListItem Text="Select" Value="0"></asp:ListItem>--%>
</asp:DropDownList>
<asp:Label ID="lblId" runat="server" Text='<%# Eval("Id") %>' </asp:Label>
</ItemTemplate>
</asp:TemplateField>
So Fetched Id will be visible next to dropdownlist. Make sure its displaying correct value

Hiding GridView Columns with ItemTemplate

I Have a GridView in .aspx page that I want to hide columns based on aspx.cs BindData() method. I have tried using below code but not able to hide. I am using Asp.net with C#.
Below is my GridView with columns and I have also included the Button click code.

With the GrideView.DataBind() you're calling a PostBack that will undo any changed you've made to the front end. Try doing the work on the columns after the DataBind.
