Re: Assign a Textbox in the parent page from a ModalPopup in asp.net

17-Feb-11 23:40

I see a lot of people have been asking this question, some was because of the if postback check , but mine is different. i am using AjaxModalExtender to show my popup on the server side. this is my markup

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="TestPage.aspx.cs" Inherits="PopTester.TestPage" %>

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<style type="text/css">

 .modalBackground
{     background-color: Yellow;
      filter: alpha(opacity=60);
      opacity: 0.6;
}

   </style>

 
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
        <asp:ScriptManager ID="ScriptManager1" runat="server"> 
    </asp:ScriptManager>

    <asp:Panel ID="Panel1" runat="server">

    <asp:Button ID="Button1" runat="server"

    Text="CreateModal" OnClick="Button1_Click" />

    </asp:Panel>


         <asp:Panel ID="ModalPanel" runat="server" Style="display: none" HorizontalAlign="Center" BackColor="Green">
             <div>
     <asp:UpdatePanel ID="Update" runat="server">
     <ContentTemplate>
        <asp:GridView ID="GridView1"  AutoGenerateColumns="false" runat="server" Height="176px" Width="453px">
        <Columns>
        <asp:TemplateField HeaderText="ID">
        <ItemTemplate>
        <asp:CheckBox ID="chkId" runat="server" />
        <asp:Label ID="lblId" runat="server" Text='<%#Eval("ID")%>'></asp:Label>
        </ItemTemplate>
        </asp:TemplateField>
        
        <asp:TemplateField HeaderText="Name">
        <ItemTemplate>
        <asp:Label ID="lblname" runat="server" Text='<%#Eval("Name") %>'></asp:Label>
        </ItemTemplate>
        </asp:TemplateField>

        
        <asp:TemplateField HeaderText="Lastname">
        <ItemTemplate>
        <asp:Label ID="lblLastname" runat="server" Text='<%#Eval("Lastname") %>'></asp:Label>
        </ItemTemplate>
        </asp:TemplateField>
        </Columns>

        </asp:GridView>

             <asp:Button ID="btnPickrecord" runat="server" Text="Pick Record" 
             onclick="btnPickrecord_Click "   />
    <asp:Button ID="btnload" runat="server" onclick="btnload_Click"  
        Text="Load Data" />
                </ContentTemplate>
     </asp:UpdatePanel>
     
        </div>
        <asp:Button ID="btnCancel" runat="server" Text="Close Me" 
                 onclick="btnCancel_Click" />
    </asp:Panel>
        <asp:TextBox ID="txtreference" runat="server" AutoPostBack="True"></asp:TextBox>
        <p>
            &nbsp;</p>
    </form>
</body>
</html>

as you can see i have a gridview that will be on the modal and its working fine, now after the grid has returned some results, i will select one record via the checkbox on the Grid and click the button "btnPickrecord" and this will fire my server side code

protected void btnPickrecord_Click(object sender, EventArgs e)
{
         foreach (GridViewRow dataItem in GridView1.Rows)
        {

            CheckBox chkselect = (CheckBox)dataItem.FindControl("chkId");

            if (dataItem.RowType == DataControlRowType.DataRow)
            {
                  if (chkselect.Checked)
                  {
                      Label lblReferenceNumberID = (Label)dataItem.FindControl("lblId");

                      txtreference.Text = lblReferenceNumberID.Text;
                  }
            }
         }
}

the breakpoints got a hit and i stepped through it and i the value get assigned to the textbox txtreference.Text , but when i close the modal the textbox is empty , or while the modal is open i can see the value does not reflect in the parent page. Here is the Code for invoking the modal

protected void Button1_Click(object sender, EventArgs e)
        { 
            AjaxControlToolkit.ModalPopupExtender modalPop = new AjaxControlToolkit.ModalPopupExtender();

            modalPop.ID = "popUp";

            modalPop.PopupControlID = "ModalPanel";

            modalPop.TargetControlID = "Button1";

            modalPop.DropShadow = true;

            modalPop.BackgroundCssClass = "modalBackground";

            modalPop.CancelControlID = "btnCancel";

            this.Panel1.Controls.Add(modalPop); 

            modalPop.Show();
        }

Thanks

Re: Assign a Textbox in the parent page from a ModalPopup in asp.net

Hi,
This is because your textbox txtreference is outside the UpdatePanel.
You should understand the partial postback and how UpdatePanel works. Then you will yourself recognize why it is not updating your txtreference TextBox.
In summary, UpdatePanel updates only the partial content in UI.

For now, you can do your job by any of the 2 ways:
1. Either put your target TextBox also inside update panel. Or...
2. Do it using javascript by calling a javascript function in Sys.Application.add_load event.

For any details, you can google.

Hope this will help you.

I understand that , but i did not want to add it inside the Update Panel. I will figure out what to do.

thanks

Then, you wish to consider the second approach mentioned:

Do it using javascript by calling a javascript function in Sys.Application.add_load event.

You could try taking him/her to a movie, maybe dinner... see where it goes from there? Poke tongue | ;-P

Seriously, though, I really don't understand your question. Why do you want to do it this way? Why don't you want to use SQL? SQL is infinitely better for querying data - that's what it does.

Please explain further?

You can create a datatable entirely in code, add the columns to it, and populate it, then just use it as if you had loaded it from a database.

Are you using C# or VB? I'll post a sample when I know which language you like.

Hi,
This is called Pivoting of Data.
Please have a look over my article: Pivoting DataTable Simplified[^]

Adding a C# UserControl DLL in ASP Web Page

17-Feb-11 8:15

Good Evening My friends

I have been helping you , now its your turn to help Smile | :)

Due to Limitations in the Telerik, meaning that there is no nice Pop Control , and i want to create my own as i did in my previous article. I have used the DevExpress Popup Control and i have a Telerik Gridview inside it and i can nicely search for records and i can select the record from the Grid and i have a button that saves take an ID of that record like

protected void btnselect_Click(object sender, EventArgs e)
   {
       String Ref =null;

       foreach (GridDataItem dataItem in grdactsandbills.MasterTableView.Items)
       {

           CheckBox chkselect = (CheckBox)dataItem.FindControl("chkselect");

           if (chkselect.Checked)
           {

               Label lblReferenceNumberID = (Label)dataItem.FindControl("lblID");

               Ref = lblReferenceNumberID.Text;
           }

       }
       txtreferencenumber.Text = Ref;
   }

this Button is in a PopupModal(DevExpress) , when this button is Clicked if assign that value to a textbox that is not part of the modal. and you can see i am doing it on the server side and the break point goes there and the watch shows that yes the value has been assigned to the textbox, but after i close the pop, the Textbox is empty. I am just buffled by this. Below is my markup

 <asp:UpdatePanel ID="Update1"  runat="server">

Yes, you can bind List to gridView for display.

This [^] looks as Bes and easiest way to do same.

You simply need to do:

GridView1.DataSource = myList
GrdiView1.DataBind();

myList

can be ArrayList or any other list.
