Change as Below :

<asp:linkbutton id="lnkEdit" runat="server"text="Edit" commandname="Edit"/>
<asp:linkbutton id="lnkdelete" runat="server" text="Edit" commandname="Delete"/>


Code Behind:

if (e.CommandName.equals("Edit"))
{
       int index = System.Convert.ToInt32(e.CommandArgument);
else if(e.commandname.equals("Delete"))
{
         int index = System.Convert.ToInt32(e.CommandArgument);
}


protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            var LinkButton2 = (Button)e.Row.FindControl("btnrate");
            LinkButton2.CommandArgument = e.Row.RowIndex.ToString();
        }
    }

Hi,
Try this:
HTML:(In the item template of your gridview)

ASP.NET

<asp:linkbutton id="lnkEdit" runat="server" text="Edit" commandname="Edit"/>
<asp:linkbutton id="lnkEdit" runat="server" text="Edit" commandname="Delete"/>

Code Behind:

C#

if (e.CommandName=="Edit")
{
    //do edit operation
}
else if (e.CommandName=="Delete")
{
    //do the deletion
}

int index = System.Convert.ToInt32(e.CommandArgument); you can get the index of particular row clicked.
start from 0.

i want to check which "ROW" is clicked in row_command event

[no name] 27-Jul-12 6:46am

int index = System.Convert.ToInt32(e.CommandArgument);

you can get sure the index of clicked row...

delete the GridViewRow gr = (GridViewRow)grdOTIF.SelectedRow;
no need to write two things for the row checking.

vaibhav mahajan 27-Jul-12 7:25am

it is giving error at the

int index = System.Convert.ToInt32(e.CommandArgument);

line

vaibhav mahajan 27-Jul-12 7:30am

Error:Input string was not in a correct format.

[no name] 27-Jul-12 7:33am

try this : on RowCreated Event
protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
var LinkButton2 = (Button)e.Row.FindControl("btnrate");
LinkButton2.CommandArgument = e.Row.RowIndex.ToString();
}
}

and check now..
