如何在删除数据前提示是否删除？ 删除完了再返回页面怎么弄
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
string id = e.CommandArgument.ToString();


if (e.CommandName=="del")
{
string sc = "delete from t_users where user_id=" + id + "";

DbHelper db = new DbHelper();
DbCommand cmd = db.GetSqlStringCommond(sc);

if (db.ExecuteNonQuery(cmd) != 0)
{

Response.Write("<script>alert('删除成功')</script>");
return;
}
}
}
这是我的删除代码

[解决办法]
Response.Write("<script>alert('删除成功');window.location='" + Request.RawUrl + "'</script>");
[解决办法]
在前台加
<asp:TemplateField HeaderText="删除" ShowHeader="False">
<ItemTemplate>
<asp:LinkButton ID="lb_delete" runat="server" CausesValidation="False" CommandName="Delete"
Text="删除" OnClientClick='return confirm("此删除操作不可恢复，您确认删除此栏目吗？")'></asp:LinkButton>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>
