使用下拉列表在弹出窗口中填充文本框 [英] Populate textboxes in a popup using a dropdown

问题描述

我有一个弹出窗口，其中包含一个下拉列表和几个文本框.当我单击下拉列表时，它应该填充弹出窗口中的文本框，但弹出窗口消失.
如何通过不将下拉菜单设置为AutopostBack false来解决此问题?

以下是带有下拉菜单和文本框的面板.

I have a popup that contains a dropdown list and few textboxes. When I click the dropdown it should populate the textboxes inside the popup but the popup disapears.
How can i solve this by not making my dropdown to be AutopostBack false?

Below is my panel with dropdown and textbox.

<asp:Panel ID="PNL" runat="server" style="display:none; width:900px; background-color:White; border-width:2px; border-color:Black; border-style:solid; padding:20px; ">
                    <%-- Form to finalize appointment--%>

  <table id="Table1" runat="server">
   <tr>
   <td>
   Select Patient
   </td>
    <td style="width: 166px">
        <asp:DropDownList ID="ddlPatientID" runat="server"

            AutoPostBack="true"

              onselectedindexchanged="ddlPatientID_SelectedIndexChanged"

            ForeColor="Black"   height="22px" Width="162px"

            style="border:1px inset black" >

        </asp:DropDownList>
   </td>
   </tr>
       <tr>
           <td>
               Name</td>
           <td style="width: 166px">
               <asp:TextBox ID="txtViewPatientName" runat="server"

                   ForeColor="Black" ReadOnly="True" CssClass="textbox"></asp:TextBox>
           </td>

在下面，我有一列在gridview内.当我单击LinkBut​​ton时，将出现带有下拉菜单和文本框的面板.

Below I have a column that is inside gridview. When I click the LinkButton, the Panel with the dropdown and textbox will apear.

<Columns >

             <asp:TemplateField HeaderText="Create Appointment">

           <ItemTemplate>
               <asp:LinkButton ID="createAppointment" runat="server"  OnClick="createAppointment_Click" OnClientClick='<%# "frmFindAppointment.aspx?Fullname=" + HttpUtility.UrlEncode(Eval("Fullname").ToString())+"&RecordNumber="+ HttpUtility.UrlEncode(Eval("RecordNumber").ToString())+"&Date="+  HttpUtility.UrlEncode(Eval("Date").ToString())+"&SlotID="+ HttpUtility.UrlEncode(Eval("SlotID").ToString())+"&Timeslot="+ HttpUtility.UrlEncode(Eval("Timeslot").ToString())  %>' Text="Create Appointment" />
            <ajaxToolkit:ConfirmButtonExtender ID="ConfirmButtonExtender2"  runat="server"

                       TargetControlID="createAppointment"

                        DisplayModalPopupID="ModalPopupExtender1" />
           <ajaxToolkit:ModalPopupExtender  BackgroundCssClass="modalBackground" ID="ModalPopupExtender1" runat="server" TargetControlID="createAppointment" PopupControlID="PNL" OkControlID="ButtonOk" EnableViewState="false" />


           </ItemTemplate>
       </asp:TemplateField>

              </Columns>

现在，当我在下拉菜单中选择一个选项时，弹出窗口消失，并且我希望它静止不动，如何使它保持竖立状态?

Now when I select an option in my dropdown,the popup disapears, and i want it to stand still, how can i make it stand stil?

推荐答案

尝试使用dropdownlist和文本框位于两个单独的updatepanels(即ajaxupdatepanel)中

并在当前面板上创建一个ID = ButtonOk
的按钮
这可能对您有帮助

Try using dropdownlist and Textbox inside two separates updatepanels(ie ajaxupdatepanel)

and on your current panel make a button with ID= ButtonOk
