Please share code of rowcommand too.

GDdixit 2-Feb-13 3:54am

int index;

index = Convert.ToInt32(e.CommandArgument);

GridViewRow row = gridview1.Rows[index];
label lbl=GridView1.rows[index].cells[0];
string VOrderId=lbl.Text;

and then ....
here i perform my delete operation with a simple procedure..

actually i understand the problem but can not finding solution...
i think problem is that value of row index is start from zero....

but when i using paging ....row index value seen to be start from negative(i think so)...so any help frnds...?

Solution 1

Try below code in your rowcommand event of gridview

protected void gridview1_RowCommand(object sender, GridViewCommandEventArgs e)

{

        int index = 0;

        index = Convert.ToInt32(e.CommandArgument.ToString());

        GridViewRow row = gridview1.Rows[index];



}

Just call the fillgrid function as follows .
Solution 1

C#

FillGrid();
   grdView.PageIndex = e.NewPageIndex;
   grdView.DataBind();

Solution 2
Add the following code in Page index Changing

C#

if (CustomersGridView.EditIndex != -1)
    {
      // Use the Cancel property to cancel the paging operation.
      e.Cancel = true;

      // Display an error message.
      int newPageNumber = e.NewPageIndex + 1;
      Message.Text = "Please update the record before moving to page " +
        newPageNumber.ToString() + ".";
    }
