                    </ItemTemplate>
                </asp:TemplateColumn>

Answer 1

// ASP.NET 1.x// .aspx
<asp:DataGrid ID="DataGrid1" runat="server" OnPageIndexChanged="DataGrid1_PageIndexChanged" OnItemDataBound="DataGrid1_ItemDataBound">
            <Columns>
                <asp:TemplateColumn>
                    <ItemTemplate>
                        <asp:LinkButton ID="btnDelete" runat="server" CausesValidation="false" CommandName="Delete" Text="Delete"></asp:LinkButton>
                    </ItemTemplate>
                </asp:TemplateColumn>
            </Columns>
        </asp:DataGrid>
// .aspx.cs
 protected void DataGrid1_ItemDataBound(object sender, DataGridItemEventArgs e)
    {
        LinkButton btnDelete = e.Item.FindControl("") as LinkButton;
        if (btnDelete != null) btnDelete.Attributes["onclick"] = "if(!confirm('deleting?')) return false;";
}

Answer 2

ASP.NET 1.x　是要用模板列吗？如果是的话那就没有实际意义了，我问的是只用按钮列，// .aspx.cs
 protected void DataGrid1_ItemDataBound(object sender, DataGridItemEventArgs e)
    {
        LinkButton btnDelete = e.Item.FindControl("") as LinkButton;
        if (btnDelete != null) btnDelete.Attributes["onclick"] = "if(!confirm('deleting?')) return false;";
}这段代码我试过了，运行没问题，但是并不能将脚本绑定到按钮列。
