The first is directly in the Aspx page GridView template column. This has the disadvantage of starting again by page 2.
The second method is calculated when paging, which adds up downward.
There is another way to put it in the cs code, similar to the second.
<asp:TemplateField HeaderText=" The serial number " InsertVisible="False">
<ItemTemplate>
<%#Container.DataItemIndex+1%>
</ItemTemplate>
</asp:TemplateField>
The second method is calculated when paging, which adds up downward.
<asp:TemplateField HeaderText=" The serial number " InsertVisible="False">
<ItemStyle HorizontalAlign="Center" />
<HeaderStyle HorizontalAlign="Center"/>
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# this.GridView1.PageIndex * this.GridView1.PageSize + this.GridView1.Rows.Count + 1%>' />
</ItemTemplate>
</asp:TemplateField>
There is another way to put it in the cs code, similar to the second.
<asp:BoundField HeaderText=" The serial number " ></asp:BoundField>
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowIndex != -1)
{
int indexID = this.GridView1.PageIndex * this.myGridView.PageSize + e.Row.RowIndex + 1;
e.Row.Cells[0].Text = indexID.ToString();
}
}
