How to create a delete button in GridView?

Question

I made another Column in my GridView called delete. When delete is clicked, the row should be deleted or in other words, I need to get the current row's user name to delete it.

1. Which event should I use? (RowDeleting, Rowdeleted etc...)
2. How do I get the username from the current row?

Answer 2

You can use the RowDeleting event, by storing the user name in the data key collection you can access it programmatically.

<asp:GridView DataKeyNames="UserName" ID="GridView1" 
     runat="server" OnRowDeleting="GridView1_RowDeleting">

Then, in the code behind use the data key to delete the record.

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
  string userName = (string) GridView1.DataKeys[e.RowIndex].Value;
  DeleteUser(userName); 
}

1:-

protected void grdLst_RowDeleting(object sender, GridViewDeleteEventArgs e)

{

    int i = Convert.ToInt32(grdLst.DataKeys[e.RowIndex].Value);
    ob.DeleteCoverage(i);
    Response.Redirect("fullcoverage.aspx");
}

2:-

    GridViewRow row = (GridViewRow)grdlist.Rows[e.RowIndex];
    string name = row.Cells[1].Text;
    Response.Write(name.Trim());

Answer 4

tablename.Rows.RemoveAt(datagrid1.currentcell.rowindex);
