Question

我有一个页面，可以发送包含下拉列表和gridview的电子邮件。

我在ddlselectedindexchanged上发布的页面有问题，并且回调oncheckchanged的gridview回复，但回调不起作用。

如果我注释掉gridview.databind，那么回调就可以了。

     <tr>
                                                        <td class="rightalignment">
                                                        <asp:Label ID="lblFacility" runat="server" Text="Facility:"></asp:Label>
                                                    </td>
                                                    <td>
                                                        <asp:DropDownList ID="ddlFacility" OnSelectedIndexChanged="ddlFacility_SelectedIndexChanged"
                                                            AppendDataBoundItems="true" runat="server" AutoPostBack="true">
                                                            <asp:ListItem Selected="True" Text="All" Value="0"></asp:ListItem>
                                                        </asp:DropDownList>
                                                    </td>
                                                </tr>
this is the gridview:

                                                                <asp:TemplateField ItemStyle-Width="5%" ShowHeader="False">

代码背后的代码：

protected void Page_Load(object sender, EventArgs e)
    {
        UIUtility.HideMessage(this.Page);
        try
        {


     if (!Page.IsPostBac

k)
            {
                this.GetFacilities(0);


this.GvEmail.DataBind();
        this.GetCorporate();
        this.GetInternalContacts();
        this.GetEmailFrom();
    }
}
catch (Exception ex)
{
        UIUtility.ShowMessage(ex.Message, true, this.Page);
    }

}


    private void GetEmailAddress()
        {
            try
            {
                FacilityBLL = new FacilityBll();
                this.GvEmail.DataSource = FacilityBLL.GetEmailAddressPerCorporateFacility(this.ddlCorporate.SelectedValue, this.ddlFacility.SelectedValue);

            }
            catch (Exception ex)
            {
                UIUtility.ShowMessage(ex.Message, true, this.Page);
            }
        }

它在更新面板中。

在评论出更新面板后，我收到了maxhttpkeys被最大化的错误。我添加到web.config 并且错误已经解决，回拨工作

Gridview数据手搞乱了帖子后面
