            if (no > 1)
            {
                no--;
            }
            else
            {
                blok = "";
            }

        }
        dataTable.Rows.Add(rows);
    } }

I don't know, how can add control asp in gridview, like label. Please help, thanks.

You can create a user control (.ascx) file and extend it to your asp file to create a custom GridView. — Mark

@hendrathings - not sure why you are not using template field and binding the datatable with the gridview. — afzalulh

One way to add controls is using OnRowDataBound event of GridView. Add a placeHolder to say, inside <ItemTemplate> of your grid view.

<asp:GridView ID="EmpGridView" OnRowDataBound="EmpGridView_RowDataBound"
     <ItemTemplate>
     <asp:PlaceHolder ID="placeholder1" runat="server"></asp:PlaceHolder>
     </ItemTemplate>
...></asp:GridView>

Ang your code behind file will have:

protected void EmpGridView_RowDataBound(object sender, GridViewRowEventArgs e)
  {
       if (e.Row.RowType == DataControlRowType.DataRow)
        { 
          // Create a label control  
          Label lbl = new Label();
          lbl.Text="MyDynamic Label";
          lbl.ID="lbl1"; // use ID values you prefer 

         // lets create one more control for example      
          LinkButton btnlink = new LinkButton();
          btnlink.Text = "Delete";
          btnlink.ID = "btnDelete";
          linkb.Click += new EventHandler(btnlink_Click);

        // add the controls to your placeholder inside <ItemTemplate>
        PlaceHolder phld = e.Row.FindControl("Placeholder1") as PlaceHolder;
        phld.Controls.Add(btnlink);
        phld.Controls.Add(lbl);

        //code to add the control to only a specific COLUMN/ Cell
        e.Row.Cells[1].Controls.Add(btnlink); // adding to 2nd Column
        // adding to last column..
        e.Row.Cells[EmpGridView.Columns.Count - 1].Controls.Add(btnlink);
            }
        }

Hope this various ways of adding controls to Templates as well as in a cell of GridView helps you.
