被常常问到的一个经典问题了，答案放到网上来。
步骤1 ASP.NET的这个地方这样设置。GridView加入 OnRowCommand 事件，模版列的按钮设置CommandArgument、CommandName
<
asp:GridView
ID
="GridView1"
runat
="server"
CellPadding
="4"
AutoGenerateColumns
="False"
OnRowCommand
="GridView1_RowCommand"
>
<
Columns
>
<
asp:BoundField
DataField
="id"
HeaderText
="编号"
/>
<
asp:BoundField
DataField
="loginID"
HeaderText
="登陆名"
/>
<
asp:TemplateField
HeaderText
="工具栏权限管理"
>
<
ItemTemplate
>
<
asp:Label
ID
="Lblqx1"
runat
="server"
></
asp:Label
>
<
asp:Button
ID
="BtnGjl"
runat
="server"
Text
="设置"
CommandArgument
='<%#Eval("id")
%
>
' CommandName="gjl" />
</
ItemTemplate
>
</
asp:TemplateField
>
</
Columns
>
</
asp:GridView
>
2 后台cs的GridView1_RowCommand方法
protected
void
GridView1_RowCommand(
object
sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "gjl")
{ Response.Redirect("NewPage.aspx?key=" + e.CommandArgument.ToString(), false);
} 
}
