I'm trying to do a similar thing -- I have a long form and in part of it, I have an updatepanel.
Inside the updatepanel I have:5 dropdowns (using the CascadingDropdown functionality)One AddProduct ButtonGrid or Repeater (haven't set it up yet)
I want the following to happen:I have the AddProduct Button disabled initially, but I want it to be enabled once the 5th dropdown is selected (so OnSelectedIndexChanged).If they click the AddProduct button, I want it to populate a Grid or Repeater.So far I am just trying to show what the selection was in a label... but nothing happens. I have an OnSelectedIndexChanged function for the last dropdown, so it enables the button, but that doesn't appear to get called. Previously, before disabling the button, I tried updating the label on button click -- and nothing there either.
It just seems like, because they are in the updatepanel, those callbacks never happen. I also do have UpdateMode = Conditional and I have both items in the triggers list.

I've build a Modal Popup extender with a DataBound DropDownList. The only problem I've got is that the DropDownList is being filled in the Page_Load. Even when I put the binding in the Load of the Modal PopUp extender there is no data inside my Dropdownlist.What am I doing wrong here? Because everything should work when I hit the TargetControlID.

I am unable to get the selected value of the DropDownList. When the user selects a value and clicks OK, the value that was loaded as the default selected value with an index of 0 is available in code behind, not the newly selected value. See the attached code for the dropdownlist in the Modal Popup form.
<div class="well" style="margin: 5px">
<asp:Label ID="lblPlanOptAdd" runat="server" AssociatedControlID="ddlPlanOptAdd">Plan Option:</asp:Label>
<asp:DropDownList ID="ddlPlanOptAdd" runat="server" CssClass="form-control" OnSelectedIndexChanged="PlanOptAdd">

I have an ajax modal popup extender in update panel. The modal popup extender has a label, checkbox and a dropdown list. When i open the popup first time (i.e Page_load) and select something and click on ok the data is populated correctly in another grid. If i open the popup second time and select some data and click on ok it is populating the grid with the current selected data as well as previously selected data.

I am sending you the code. It Has two PArts First is CLIENT SECTION and Anpother is STATION Section
1) CLIENT SECTION : It has a dropdownlist binded to SQLDataSource and with this it has an imagebutton bAddClient
bAddClient will open the ModalPopup which will ask user to Add new client. And After Adding the New client when User
will close the ModalPopup MY DropDownList is not getting Populated with the New Client. I have Used UpdatePanels Also
2) STATION SECTION : It has a DropDownList, an Image BUtton , And Grid View. In Grid View it shows station details
On particular client selcted above.
I have given the delete station command on deleting the station that particular entry doesnot goes away.
It Should not be visible after it get deleted
Now when i click on imagebutton a modalpopup will open.
Now In modalpopup i have given dropdownlist , image button(to add new station), Some station Info and save button
Now when i click on dropdownlist it used to close the modalpopup then i seet the autopostback = false. Then it works fine. Is it correct way?
Now when i click on imagebutton it asks user to add new station with a textbox , save station button. When users click on savestation button then it adds station to the DB and it should update the dropDownList of ModalPoup without closing it.
But when I am clicking on imagebutton it is closing the modalpoup.
And When user clicks on ModalPoup SSave Button in end it should update GridView of STATAION SECTION too.
<%-- ************** CLIENT SECTION START HERE*******************--%>
<p class="heading">CLIENTS</p>

<asp:ScriptManager ID="smClientMgmt" runat="server" />
<asp:UpdatePanel ID="upCMClientInfo" ChildrenAsTriggers = "true" UpdateMode="Conditional" runat ="server" >

I'm using the ASP.Net Validation controls and I want to display the Validation Summary in a JQuery Dialog instead of the native javascript alert messagebox. I've found this solution (aspsnippets) by overriding the clientside WebForm_OnSubmit() function:
<script type="text/javascript">
function WebForm_OnSubmit() {
if (typeof (ValidatorOnSubmit) == "function" && ValidatorOnSubmit() == false) {
$("#validation_dialog").dialog({
title: "Validation Error!",
modal: true,
resizable: false,
[Code] ....
The WebForm_OnSubmit() function is being rendered by the BaseValidator control and in the form tag te following attribute is being added: onsubmit="javascript:return WebForm_OnSubmit();
I am running into a problem on a page which has an UpdatePanel. The input field with the validator (1 to make it simple) is in a Panel within an UpdatePanel. The Panel is set to Visible=False at the first Page Load. There's a button inside the UpdatePanel which makes the Panel with the Validator Visible.
When this happens, the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag are not being rendered because it's an AJAX callback and the form tag is outside the updatepanel (in a master page), so the validation summary will not be shown in the jquery dialog.
Validation is being performed, so the validation summary wil be shown in a div on a page, but the validation is not being called by the WebForm_OnSubmit() function in this case, because it's not being rendered.
Here's the markup of the page:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Button ID="btnNew" runat="server" Text="New" />
<asp:Panel ID="pnlEdit" runat="server">
<table>
[Code] ....
So, when the validators are not visible at the first load and they will be made visible by an AJAX callback, the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag are not being rendered on the pag. Because of that, the WebForm_OnSubmit() function will not be called and the validation summary will not be shown in the JQuery dialog (although it is being shown in a div on the page). How can I get the Validation Summary to be shown in de JQuery dialog in this case?
Is there another function that has to be overriden for this case? I know I can use a Full Postback for the New button and then all the stuff needed is being rendered on the page, or I can make the panel not visible by using a style, but I don't prefer that because there are a lot of pages with this situation.
One solution is to use a dummy textbox with a dummy validator (with a dummy validationgroup) of which I set the display to none. Then this dummy validator will cause the the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag to be rendered.

I have a list of items in a GridView, with one column I'd like editable through a DropDownList.I do not wish to put the GridView into 'edit' mode or have any 'confirm/update/save' buttons.. I just want autopostback on the DDL, and an OnSelectedIndexChangedevent to update the row.Problem is, from my OnSelectedIndexChangedevent within the DDL, although I can see the new value to save, I can't discover the row to update from the GridView.Can anyone see how I can achieve what I wish? Other than perhaps storing the row id within the DDL? Maybe turn it around so the GridView's events are called?

I have a number of cascading dropdownlist controls on a page. The results in dropdownlist2 are dependent on the results in dropdownlist1, pretty basic stuff.
I now would like to eliminate the terrible postback or refresh of the page that occurs after the SelectedIndexChanged event fires on dropdownlist1, is it possible to do that in Ajax?
What I want the results in dropdownlist2 to populate without the obvious refresh of the page.

I have a script that I am trying to trigger an AJAX AsyncPostBack and have been trying to figure out how to get it to work. After searching the internet for a while I noticed something on all the examples. On the asp:DropDownList they use the autopoastback=true tag. If I add it to my script it works fine, if I remove it it stops working. So my question is why is the autopostback required or if it is not what might I be missing? BTY Everything is in C# and .Net 4
