<asp:GridView ID="gvorderdetail" runat="server"

<sortedascendingcellstyle backcolor="#E9E7E2">
<sortedascendingheaderstyle backcolor="#506C8C">
<sorteddescendingcellstyle backcolor="#FFFDF8">
<sorteddescendingheaderstyle backcolor="#6F8DAE">

This is the C# code:

C#

protected void gvorderdetail_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "change")
    {
        TextBox tbx = (TextBox)gvorderdetail.Rows[0].FindControl("txtitemqty");

    }
}

protected void btnchange_Click(object sender, EventArgs e)
   {

       Button btn = (Button)sender;
       GridViewRow gvr = (GridViewRow)btn.NamingContainer;
       int getindex = gvr.RowIndex;




       gvorderdetail.Rows[getindex].Cells[3].Style.Value = "red";
       gvorderdetail.Rows[getindex].Cells[0].Attributes["style"] = "background-color:Red";
       gvorderdetail.Rows[getindex].Cells[1].Attributes["style"] = "background-color:Red";
       gvorderdetail.Rows[getindex].Cells[2].Attributes["style"] = "background-color:Red";
       TextBox tbx = (TextBox)gvorderdetail.Rows[0].FindControl("txtitemqty");
   }

But the code above doesnt place the textbox in the quantity column.

Solution 3

Try using like this.

C#

protected void gvorderdetail_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "change")
    {
        int index = Convert.ToInt32(e.CommandArgument);

      // Retrieve the row that contains the button clicked      
      GridViewRow row = gvorderdetail.Rows[index];
       
      //Assign Value to the Text Box.  
      TextBox tbx = (TextBox)row.FindControl("txtitemqty");
      tbx.Text = "Some Text";     

      // Update the row.
      gvorderdetail.UpdateRow(index, false);
    }
}

It gives error on the first line
int index = Convert.ToInt32(e.CommandArgument);
Input string was not in correct format.

Thomas ktg 24-Sep-13 5:54am

include CommandArgument like this in the button.
<asp:TemplateField>
<itemtemplate>
<asp:Button ID="btnchange" runat="server" Text="Edit" OnClick="btnchange_Click" CommandName="change" CommandArgument="<%# ((GridViewRow) Container).RowIndex %>" />

Doesnt works out it gives the following error.
The GridView 'gvorderdetail' fired event RowUpdating which wasn't handled.

Thomas ktg 24-Sep-13 7:31am

comment the row and run else add this

protected void GridView1_RowUpdating(object sender, GridViewEditEventArgs e)
{
// Write here code for edit Rows
}

IS it something to do with the panel.
