(转)在GridView中使用模板列LinkButton,如何知道当前的LinkButton点击在哪行记录上?

<asp:TemplateField HeaderText="Add new"> <ItemTemplate>
<asp:LinkButton ID="link1" runat="server" OnClick="lnk1Click"/>

</ItemTemplate> </asp:TemplateField>

<asp:TemplateField> <ItemTemplate>

<asp:LinkButton ID="link2" runat="server" OnClick="lnk2Click"/>

</ItemTemplate></asp:TemplateField>

<asp:BoundField DataField="NAME" / >

<asp:BoundField DataField="DESC"/>

<asp:BoundField DataField="DESC2" />

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
GridViewRow gvr = e.Row;
switch (gvr.RowType)
{
case DataControlRowType.DataRow:
{
// Retrieve controls
LinkButton link1 = gvr.FindControl("link1") as LinkButton;
LinkButton link2 = gvr.FindControl("link2") as LinkButton;
if (link1 != null)
{
link1.CommandArgument = gvr.RowIndex.ToString();
}

if (link2 != null)
{
link2.CommandArgument = gvr.RowIndex.ToString();
}
break;
}
}
}

protected void link1Click(object sender, EventArgs e)
{
// Retrieve control
LinkButton link1 = sender as LinkButton;
int rowIndex = Int32.Parse(link1.CommandArgument);
}
protected void link2Click(object sender, EventArgs e)
{
// Retrieve control
LinkButton link2 = sender as LinkButton;
int rowIndex = Int32.Parse(link2.CommandArgument);
}
