Question

我正在尝试将值从ModalPopupExtender中的列表框传递到父页面中gridview页脚行文本框中的文本框。在当前场景中，应用程序在按钮单击时中断。我尝试过使用Javascript，juery和C＃，但所有结果都相同。有人对如何做到有什么建议吗？以下是我的代码：

我试图将值从列表框“lst_PdfViewers”传递到gridview文本框“AddSupplierName”上完成按钮单击事件“btnSupplierDone_Click”

Gridview页脚行：

<FooterTemplate>                
     <asp:TextBox ID="AddSupplierName" runat="server"  >                                                             
          </asp:TextBox>
     <asp:ImageButton ID="btnlnkSupplier" runat="server" ImageUrl="../images/openDialog20.gif" 
         onclick ="lnkSupplier_Click"  /> 
 </FooterTemplate>

ModalPopupExtender：

<act:ModalPopupExtender ID="ModalPopupExtenderSupplier" CancelControlID="SupplierPopupCancel"  TargetControlID="Sample" 
   PopupControlID="Pnl_Pdfviewers" runat="server" Enabled="true"> </act:ModalPopupExtender>

Popup Div有列表框和完成按钮：

<div id="Pnl_Pdfviewers" style="display: none; width: 500px !important; height: 400px !important;"
    class="popupConfirmation">
    <div class="popup_Titlebar" id="div3">
        <div class="TitlebarRight" onclick="$get('SupplierPopupCancel').click();">
        </div>
    </div>
    <div id="div4" class="popup_Container popup_Body" style="overflow: auto; height: 125px;">
        <table id="Table2" class="table" style="table-layout: fixed; width: 450px;">
            <tr>
                <td style="word-wrap: break-word;">
                    <asp:ListBox ID="lst_PdfViewers" Width="250px" runat="server" OnSelectedIndexChanged="lst_PdfViewers_SelectedIndexChanged"></asp:ListBox>
                </td>
            </tr>
            <tr>
                <td style="word-wrap: break-word;">
                    <%--<input type="button" id="btn1"   OnClick="btnSupplierDone_Click" value="Client Button" />--%>
                    <asp:Button ID="BtnSupplierDone" runat="server" CausesValidation="False" OnClick="btnSupplierDone_Click" Text="Done" />
                </td>
            </tr>
        </table>
    </div>
</div>

.cs btnSupplierDone_Click事件

protected void btnSupplierDone_Click(object sender, EventArgs e)
{
    if (lst_PdfViewers.SelectedValue != null)
    {
        var footerRow = gvPITransactionData.FooterRow;
        var txtAddSupplierName = (TextBox)footerRow.FindControl("AddSupplierName");
        lst_PdfViewers.SelectedValue = txtAddSupplierName.Text;
        // ModalPopupExtenderSupplier.Hide();
    }
}

切换这些控件时，我得到了正确的结果。你有：

lst_PdfViewers.SelectedValue = txtAddSupplierName.Text;

但是如果你想在页脚行中lst_PdfViewers的值使用：

txtAddSupplierName.Text = lst_PdfViewers.SelectedValue;

如何在buttonclick上将ModalPopupExtender的值传递给Gridview页脚行文本框
