Find And Interact With A User Control On Page From Separate User Control?
Oct 17, 2011I have an aspx page that has two different user controls. I want to find user control A and be able to set properties, etc., from user control B.
I was thinking I could do something like this:
Dim CMFilters As Control = Me.Parent.FindControl("CMFilters")
...but that doesnt work to be able to set properties and call methods. I somehow need to get the user control and and declare it as that user control type.
Asp.net - Set Master Page On Page Preinit Based On Custom User Control Method Result?
Apr 27, 2011I have a user control that checks if a certain query string and session value are present then returns a boolean based on that, if it's true I want to set the master page. The page is throwing an Object reference exception when it tries to call the method EditUser1.UserAuthorization(). Why is this happening? I imagine that the method doesn't exist at that point in the stack. Protected Sub Page_PreInit(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreInit

Access A Page Variable From User Control Placed On That Page From VB?
Dec 27, 2009I want to access a page variable from a user control placed on that page. All the solutions work in C# via casting to the page class. The problem is that this doesn't work in VB. The page class is not selectable from the Intellisense dialog. Manual typing results in the error type not defined. It is strange that C# can do this without a problem. What is the proper solution for this in VB? I had other cases where I needed to access a control on the main page. C# again uses a cast to the page class to access the control. This doesn't work in VB again. So how can I access the page class from a user control in generell?

Feb 12, 2011I have an asp.net usercontrol which represents a "popup" dialog. Basically, it's a wrapper for the jQuery UI dialog which can be subclassed to easily make dialogs. As part of this control, I need to inject a div into the page the control is used on, either at the very top or very bottom of the form so that when the popup is instantiated, it's parent is changed to this div. This allows "nested" popups without the child popup being trapped inside the parent popup.
The trouble is, I can't find a safe way to inject this div into the page. A usercontrol doesn't have a preinit event, so I can't do it there, and calling Page.Form.Controls.Add(...) in Init, Load or PreRender causes the standard exception "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."
I thought I had found a solution by using. ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, UniqueID + "_Dialog_Div", containerDiv, False) which seemed to work well normally, but recently a coworker tried putting an UpdatePanel inside the dialog and now she's getting the error "The script tag registered for type 'ASP.controls_order_viewzips_ascx' and key 'ctl00$ContentBody$OViewZips_Dialog_Div' has invalid characters outside of the script tags: . Only properly formatted script tags can be registered."
How are you supposed to add controls to the pages control collection from inside a user control?

C# - Using A User Control In A Base Page Class
May 21, 2009I have a base page class that inherits from Page. We'll call it SpiffyPage. I also have a user control called SpiffyControl. I then have an aspx page, ViewSpiffyStuff.aspx, that inherits from SpiffyPage. On page load, the SpiffyPage class is supposed to inject a SpiffyControl into the aspx page. The problem is that SpiffyControl is a user control, and to instantiate that in the code behind one has to access the ASP namespace, sort of like: ASP.controls_spiffycontrol_aspx MyControl;
But SpiffyPage isn't an aspx page, it's just a base page, and as such I can't access the ASP namespace, and I therefore can't instantiate a SpiffyControl in order to inject it. How can I achieve my goal?
Edit: One important point is that I must have a reference to the actual control type so I can assign values to certain custom Properties. That's why a function like LoadControl, which returns type Control, won't work in this case.

.net - Declarative Event Handling From ASP.NET User Control To Page?
Sep 30, 2009I am trying to figure out how to declaratively pass in a event handler into a user control, but I am stumped. All I can make work is the user control's event handler..

Asp.net - Can A Page Raise An Event That The User Control Can Handle
Mar 13, 2009I have done this the other way many times as it makes sense (the page knows about the control as it has been added to the page and can handle the 'child' event)
Is it possible to do it the other way? I think not as the control doesn't know what page it is going to be on
The reason i ask this is that I have a modal popup on the page to ask users to login, and it is only when the user has logged in that I want my user control to go away and execute some code but I am not too sure how to tell the control this has happend?
Asp.net Vb User Control Raising An Event On The Calling Page
Apr 7, 2010i'm trying to learn about user controls. I created a user control that has a textbox and a button. What i'd like to be able to do is when i click the button in the user control, populate a label in the aspx page. I understand that i could just have a button on the page that uses some properties on the user control to get that information.. but i'd like to know how to do it with the button the user control.. the reason for this is the button is just an example.. a learning tool. if i can get this working, i'd likely be putting thing in the user control that might require this kind of passing information. Anyway.. i've found some c# examples that i tried to get working as vb.. but once started getting into the delegates and events..

Asp.net - Accessing POST Data From ASCX User Control On Parent Page?
Nov 1, 2011I have an ASP.NET page (WebForm) on which I set the content of a central DIV by dynamically loading one of five user controls during Page_Load, dependant on the stage of the application.
One of the user controls contains radio buttons and a text box together with a submit button. What I want to do is process that information when the form is posted using the submit button.
I could do this with an AJAX call using jQuery, but I don't really want to do that, so I'm trying to access the form data on postback, but on page load following the postback the data is not present in the Request.Form object.
Looking at what I need to do it seems pretty simple and I'm sure is once you've got your head around it, but I can't find out how to carry this out. Some of the things I have read refer to event bubbling, but that doesn't make too much sense in this scenario.
EDIT: To clarify, I want to post the page back to itself to capture the values from the form elements via the Request object, store them in the database, and then display a confirmation message (or something else) on postback, and not re-display the same control again. So I won't be loading the same user control again.

View 10 RepliesCreate A WebBrowser Control And Navigate To A Page To Login?
Oct 26, 2010I'm using a WebBrowser control in my current program in a bit of a bastardized way: I don't use it visually, I just use it because I'm more familiar with its events.
So, basically, I create a WebBrowser control and navigate to a page to login. Then, when logged in, I create a new WebBrowser control and navigate to a different page.
I've used this program for four months with no difficulty. Starting today, though, the second phase of that has been going really, really slowly. What used to take 3-5 seconds is taking 25-30 seconds. It still works eventually, it just takes a while.
Usually I would assume this was a server problem. However, navigating to the exact same URL in Firefox happens extremely quickly. Weirder still, within the program there is a user WebBrowser control -- I can copy/paste the URL the previous (not visible) WebBrowser was navigating toward into this user WebBrowser, and it goes just fine.
What in the world could be holding up this other "custom" WebBrowser? I don't even know where to begin in diagnosing this.It might be important to note that the site this is working based off recently underwent some changes -- but I can't imagine why that would affect only these "custom" WebBrowsers and not the user one in the same program.
Asp.net - Refresh DataGrid And DropDown On Main Page After Hiding Modal Popup?

It seems I need to cause a postback, but I don't know what needs to be changed. Some posts have talked about the extender being misplaced.<asp:Content ID="Content1" ContentPlaceHolderID="Head" Runat="Server">
