Set Focus to TextBox in GridView when click on Edit Some time we have requirement to set focus in gridview,so here i am describing to how to this.
Drag and drop a gridview and bind it according to below code.

           Ds = obBLLclass.GetData();  
           if (Ds.Tables[0].Rows.Count > 0)  
           {  
                gridview.DataSource = Ds;  
                gridview.DataBind();  
           }   
      }  
      catch (Exception ex)  
      {  
           Message.Text = ex.Message;  
      }  
 }  
 protected void gridview_RowEditing(object sender, GridViewEditEventArgs e)  
 {  
      gridview.EditIndex = e.NewEditIndex;  
      GridViewBind();  
      gridview.Rows[e.NewEditIndex].FindControl("txtname").Focus();  
 }
