<asp:TemplateField HeaderText="序号" InsertVisible="False">
<ItemStyle HorizontalAlign="Center" />
<HeaderStyle HorizontalAlign="Center" Width="5%" />
<ItemTemplate>
<%#Container.DataItemIndex+1%>
</ItemTemplate>
</asp:TemplateField>
<ItemStyle HorizontalAlign="Center" />
<HeaderStyle HorizontalAlign="Center" Width="5%" />
<ItemTemplate>
<%#Container.DataItemIndex+1%>
</ItemTemplate>
</asp:TemplateField>
第二种方式分页时进行了计算,这样会累计向下加.
<asp:TemplateField HeaderText="序号" InsertVisible="False">
<ItemStyle HorizontalAlign="Center" />
<HeaderStyle HorizontalAlign="Center" Width="5%" />
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# this.MyListGridView.PageIndex * this.MyListGridView.PageSize + this.MyListGridView.Rows.Count + 1%>'/>
</ItemTemplate>
</asp:TemplateField>
<ItemStyle HorizontalAlign="Center" />
<HeaderStyle HorizontalAlign="Center" Width="5%" />
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# this.MyListGridView.PageIndex * this.MyListGridView.PageSize + this.MyListGridView.Rows.Count + 1%>'/>
</ItemTemplate>
</asp:TemplateField>
还有一种方式放在cs代码中,和第二种相似.
<asp:BoundField HeaderText="序号" >
<ItemStyle HorizontalAlign="Center" />
<HeaderStyle HorizontalAlign="Center" Width="5%" />
</asp:BoundField>
<ItemStyle HorizontalAlign="Center" />
<HeaderStyle HorizontalAlign="Center" Width="5%" />
</asp:BoundField>
protected void myGridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowIndex != -1)
{
int indexID = this.myGridView.PageIndex * this.myGridView.PageSize + e.Row.RowIndex + 1;
e.Row.Cells[0].Text = indexID.ToString();
}
}
{
if (e.Row.RowIndex != -1)
{
int indexID = this.myGridView.PageIndex * this.myGridView.PageSize + e.Row.RowIndex + 1;
e.Row.Cells[0].Text = indexID.ToString();
}
}
都是非常简单的,其实原理都是一样的.实现同一种效果,方法很多,实际上读取数据的时候也可以实现.
