Usercontrols - How To Add A New Javascript From A User Control Loaded By Callback
Sep 10, 2010I'm doing a menu that loads levels dynamicly, when you click on a item the next level is loaded asynchronously. For each menu item I have a user control. Every user control is declared in its parent, for example, the "secondlevelcontrol" has the reference to "thirdlevelcontrol".With this level of nesting, I want to manage the asynchronous calls on every user control so, when the first level is loaded the javascript to load the second is loaded too. When the second level is loaded the javascript to load the third is loaded too.
To do asynchronous calls I'm implementing ICallbackEventHandler interface. As you can see in the examples, controls are added to the page as plain html. The method "ProcessOnLoadEvent" executes all lines of the "OnLoad" event of the user control.An example of the implementation is this for the user control of fourth level:
public string GetCallbackResult()
{
return _callbackRendering;
}

Web Forms :: Finding UserControls Within A PlaceHolder Control?
Sep 28, 2010I am having problems finding my UserControls inside the Controls collection of a Placeholder control.
I have a ListView control with a PlaceHolder control in its ItemTemplate. OnItemdataBound for the ListView control I am adding a custom UserControl to the Controls collection of the Placeholder control. It all renders fine. My problem is when I try to find my user controls in the Placeholder. I just can't get it back. My code is below.
My objective here is to get to the input controls within my UserControl and call the save method of this.
PlaceHolder intakeBenefitHolder = null;
protected void lvIntakeBenefits_ItemDataBound(object sender, ListViewItemEventArgs e)
{
if (e.Item.ItemType == ListViewItemType.DataItem)
{
using (ListViewDataItem item = (ListViewDataItem)e.Item)

Usercontrols - How To Load All Assemblies In Bin To Find A User Control
Oct 25, 2010Part of a web application we have uses an in-house web control assembly. This assembly contains several web user controls where several of these are used by other web controls within the same assembly.
The assembly is built as a website with a web deployment project.
The main web application's pages are dynamically compiled through a service into a single assembly and placed into the appropriate bin folder. In our development server the old assemblies aren't always tidied up and removed, meaning the folder gets full of old assemblies.
When the page that uses the in-house web control assembly (mentioned above) runs, the asp.net instance throws an out of memory as it loads all the old assemblies in an attempt to determine which assembly houses the reference to the user control being used by the other user control inside the same assembly.
We've been using the following inside the top level user controls to register the other controls
<%@ Register Src="~/....ascx" TagPrefix="UC" TagName="...." %>
Of course when the application runs this gives no information as to which assembly it can find it in.
Is there anyone that's come across this problem before? It's not really a problem as our live servers use a clean up tool to remove old assemblies, but there are still potential situations where we could get out of memory caused by this (for example the tool stops working!), so it would be nice to resolve this problem.
Here is the stack trace

Usercontrols - Server-side Value Being Assigned In This Custom Control?
Jul 15, 2010I am looking at somebody else's code and in it there is a user control:
<UserControl:Comments ID="Comments1" runat="server" ObjectID="4" ObjectRecordID='<%#((Alert)Container.DataItem).AlertId %>'></UserControl:Comments>
What I don't quite understand is how the value for ObjectRecordID gets assigned. I
understand by looking at the code that AlerId is getting assigned to ObjectRecordID
but how is ((Alert)Container.DataItem).AlertId grabbing its value?

View 5 RepliesUsercontrols - Button Click Not Caught (button In User Control Which Is Dynamically Loaded In Repeater)?
Jun 4, 2010I have written a user control that captures some user input and has a Save button to save it to the DB. I use a repeater to render a number of these controls on the page - imagine a list of multiple choice questions with a Save button by each question.
I am loading the user control inside the repeater's ItemDataBound event like this (code simplified):
[code]....
The problem is that when the Save button is clicked, the page posts back, but lbnUpdate_Click is not called. The Page_Load event of the page itself is called however.
I should mention that the repeater is part of a user control, and that user control is loaded inside another user control (this is a DotNetNuke site which makes heavy use of user controls). The Save button link looks like this:
javascript:__doPostBack('dnn$ctr498$AssignmentsList$rptAssignments$ctl04$ctl00$lbnUpdate','')

Read Flash Cookie From Javascript
Oct 27, 2010We have a flash video that was created for our project, we dont the source so we have to work around the compiled flash file. We are going to host the video on our domain and the video creates a sol cookie (flash cookie) file to store how far the user has proceeded though the video. So my plan is to access this cookie to see how far the user has progressed and then fire an event when they have finished the movie.
I have been googling for some help but haven't found to much. I have found out that its possible to do in javascript and I have found some .net sol file viewers but haven't seen any examples I can get my mind around. I have watched the traffic that gets created with fiddler and every time the next button is clicked a new request is fired with the swt file that is being accessed. I would also be happy with tracking every time one of these swt files has been accessed as well.

Web Forms :: Read The Selected Value Of A User Control's DropDownList?
Feb 26, 2011I have a survey form, survey.aspx, that looks for information about 3 different people (hiking guides) who are all contained in a single DropDownList. Instead of repeating the list over and over, I figured I'd put them all into a single user control, GuideList.ascx, shown here.
