Trigger An Update Panel From A Drop Down List In User Control?

Mar 23, 2010

I have a user control in a master page with two drop down lists. When the user selects an item out of either ddl, I want to load a specific user control inside an update panel on the content page. I can't figure out how to get the user control to trigger the update panel.


<%@ Register src="toolbar.ascx" tagname="toolbar" tagprefix="uc1" %>
<head id="Head1" runat="server">

AJAX :: Update Panel Not Working For Drop Down List?

Mar 30, 2010

I am using Visual Studio 2008 and created a simple ASPX page with two drop downs in it. I am using the Update Panel so that when any item is seleted in drop down 1 the second drop down selected item will change accordingly.

I was hoping the update panel will not fix the page refreshing but I am not sure what is wrong since I still see the Page refresh.

see the code below I am using.

Web Forms :: Drop Down List, User Control, Getting Value Of DDL?

Nov 17, 2010

As the tree said to the lumberjack, "I'm stumped". I've been doing .net for years, and my brain is in vapor lock...Very simple here.. I have a user control which has a dropdown list, and a button on it. The DDL is databound. When the button is clicked, I want to retrieve the value of the dropdownlist. I check to see if the page is a postback and if not, I bind the DDL.I put my user control on my master page.When the button is clicked, the value of the dropdown is not obtainable. The selectedvalue is empty. I figure this has something to do with the order of the page being regenerated.

AJAX :: Update Panel & Update Progress In User Control / Multiple Instances On Same Page

Feb 16, 2010

I have a user control, that has an update panel and update progress control in it.

I use this user control in more than 1 location on the same page.... problem is, when ucA posts back, I see the update progress control for both ucA and ucB. I assume this is because it is a user control and the update panel and progress are named the same?

Either way - how do I make it so that the update progress only displays for the proper user control?

AJAX :: Using A User Control's UpdatePanel.Update() From A Page-level Update Panel's Function Call?

Jul 14, 2010

I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.

Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.

<cust:CustomControl runat="server" ID="CustomControl1">
<asp:UpdatePanel runat="server" ID="UpdatePanel1"> <ContentTemplate>
<asp:Button id="Button1" runat="server" OnClick="DoStuff" />
</ContentTemplate> </asp:UpdatePanel>

This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.

Drop Down List In User Control Cause Full Page Postback?

Jan 14, 2011

I have the following scenario. I have a page that hosts several user controls. The user controls are all surrounded by a single update panel. All user controls have a save button on them. When the save buttons are clicked the page updates the update panel as expected. Some of the user controls contain editable list views. Whenever an action is taken on these list views, the Update Panel is NOT refreshed, but the whole page posts back. How can I get these ListViews to also refresh the Update Panel? I cannot post the code because of NDA. There are no javascript errors on the page reported by either IE8 or Chrome.

Web Forms :: Allow The User To Choose An Item, But Rather Than Populate Another Drop Down List Control?

Jun 22, 2010

I've got a drop down list that I want to populate with items from a SQL Server database, which I did successfully, but I can't figure out how to write an if statement that will clear the drop down list based on a selected index and repopulate it with data from another table. The drop down list is inside an update panel that auto posts back.

Basically I want to allow the user to choose an item, but rather than populate another drop down list control, i just want to repopulate the current one with new data.I'm guessing that if I want to get data from more than one table the code below isn't going to work for me. Could I get the data from all the tables at once and store each table data in its own variable until I need to use it? (Each table will have under 10 items, in 5 tables.)

Here is the code to get the data from the database:[Code]....

AJAX :: How To Update Panel With User Control

Nov 5, 2010

I have 2 user controls. The first user control generates custom paging and assigns the output as a string literal. The second user control is a simple repeater which uses values from the paging control via a query string to decide which relevant chunk of data to retrn.

The custom paging control is embeded in the custom reapeater control. In my my page, I simply call the customer erpeater control and everything works treat.I now want to add update panels to this but I can't think where to start.

The paging control looka like this.
