in page_load event call one method like : showLink()

in this method write the condition of link button like

void showLink()
{

   for (int i = 0; i < GridView1.Rows.Count; i++) {
LinkButton lk=(LinkButton)GridView1.Rows[i].FindControl("name of your link button");

//condition to display
if()
{
lk.Visible=true;
}
else
{
lk.Visible=false;
}
  }
}

and also call this method in

protected void GridView1_DataBound(object sender, EventArgs e)
   {
   showLink()
   }

hi

in gridview there are one event RowDatabound. It uses for finding each and every row data bound in grid. You can find your linkbutton and button over there.

In rowdatabound write below code

Linkbutton lnkbutton = (Linkbutton)e.item.Findcontrol("linkbutton");

you can find this control value and you can set visible true or false accordingly as per your requirement.

Hi Deepak,

You can use below commands to enable select/edit/delete buttons of the gridview at any condition point.

if(xxxxxxx)
{
//enable Select button
        GridView1.AutoGenerateSelectButton = true;

//enable Edit button
        GridView1.AutoGenerateEditButton = true;

//enable delete button
        GridView1.AutoGenerateDeleteButton = true;

}
