I have a user control inside of default.aspx page, And I have a function in the code behind of user control. I need to call that function from a code behind of default.aspx
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.
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.
Now the weird thing is I have a user control UserControl1 in which I put some JavaScrdipt logic there, and I have another user control UserControl2 and I registered both in the page called Page1.aspx.I would like to call the JavaScript function resided in UserControl1 from UserControl2, however, I got an error saying the function is not defined. I think both user controls are loaded before I use them then I think the JavaScript function can been seen anyway in that page.
I have two user controls I have some functions written on those two controls. Is it possible to invoke a function written on one user control from another user control.

I defined a JavaScript function inside a user control.If I have multiple instances of the user control on my .aspx page, how do I prevent multiple function definitions in the resulting HTML code?
I have designed one user control, and used on my aspx pages whereever needed. My user control does not have tag. Now I want to call some javascript function onload of this user control. How to achieve?
I've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?
I'm working on an ASP.net application.I had a problem with a user control I'd designed called LocationSelector. It worked great, but I couldn't use it within an ASP:UpdatePanel. I learned, by browsing SO, that I needed to put my in-line javascript in an external file and register it with ScriptManager so that there are no Response.Write calls in the Javascript.Next, I discovered that the control worked at first, but when I enclosed it within the ASP:UpdatePanel, it would stop functioning after the first AJAX postback. I read that to fix that, I needed to replace my $(document).ready call with function pageLoad() which is automatically executed with each ASP.net page load.
Several of my pages in my ASP.net application work fine (and I was really impressed with how well the framework seemed to drive the application). However, to my dismay, I discovered that my LocationSelector control no longer works at all on three of my pages. The HTML renders, but the pageLoad (which uses jQuery to bind events on control elements) does not fire.I verified this but putting alert('pageLoad'); as the first line of my pageLoad function. On the pages that work, I see the alert. On the pages that don't work, I never see the alert, even on the initial page load.What kind of problem could be causing the pageLoad function on my user control LocationSelector to execute on some pages, but not others?
I have a javascript function on my Master page, how do I access it with a dropdownlist of a content page. Not from codebehind, I can do that, but from the control itself such as the onSelectedIndexChanged event.
I have a ModalPopupExtender that needs to be hidden whenever the user clicks anywhere else on the page, window, or scrollbar. I have a function and it works if i set it to a div tag but what about when the user clicks the windows scrollbar?

have two user controls on one aspx page. UC1 has a grid which contains a link button column which user clicks. Based on the value of clicked cell, I need to show some data into UC2.How do I pass data from UC1 to UC2? How do I invoke a function of UC2 from UC1?
It's simple to create both user control from the two world : ASP.NET+Razor or MVC 3.0.But i do not known how to consume the user control FROM the razor"_layout.chtml" page.I want to put such thing within the layout page: <uc:MyTag Prop1="" Prop2="" />So i need to declare this directive at top of the layout file : <%@ Register TagPrefix="uc" TagName="MyTag" Src="Controls/Mytag.ascx" %>
I am trying to create a web page, that use a user-control (the user control is win-form).I am getting the message : That assembly does not allow partially trusted callers.I put the dll on c:windowsassembly, but I don't know why I getting the above.Here is my code
I have a control on a master page called "panel1". I would like to access it from my Javascript on the content page. I have tried var panel1 = document.getElementById('<%= panel1 %>'); It doesn't work since it is on the Master page.
I don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?
The script are put in the following and the block is in the .ascx page.
<script type="text/javascript"> </script>
However, the function UserControlNameInit() does not run when the page loads. It is showing in the page source. I can still call this function through FireBug console by manually typing the name of the function.
I did the same way with other user controls, and it works. Just 1-3 user controls are not working...
