Answer 1

If you are looking for Linkbutton object, thenyou can use FindControl method as:

LinkButton button1 = (LinkButton)gvdatasubcategory.Rows[0].Cells[0].FindControl("button1");
string buttonid = button1.ClientID; //gives client side id of the Linkbutton

But keep in mind that grid should contain th rows, otherwise you will get null . If you need all Linkbutton instances, then you can loop through the datarows to get each linkbutton ids.

You can try this code below:

 protected void button2_Click(object sender, EventArgs e)
 {
      foreach(GridViewRow row in  gvdatasubcategory.Rows)
      {
          LinkButton btn = (LinkButton)row.FindControl("button1");
          string strClientID = string.Empty;
          strClientID = btn.ClientID;
      }
 }
