Web Forms :: Loading User Controls Inside Text?
Apr 12, 2010
I have a scenario that I cannot fit my small brain around at the moment. I have a database driven site that also has a variable amount of user controls that go on to some pages. Some pages do not have user controls associated with them).
So I'm returning the page's body text from the data base like this:
The quick brown fox %ucUserControl1.ascx% jumps over %ucUserControl2.ascx% the fence.
I'm using a text editor for the backend that I'd like to be able to specify a user control in text format (by wrapping it in some sort of tag-- % was used for my above example, but anything will work).

I have created the user control and it has got one table with few rows in it. One row has got a text box with custom validaor and other row will have check boxes dynamically added through server side.
On the main page, i am loading that user control about 10-15 times depending upon the values from the database.
Is there any way of setting the properties of user control validator on the main page? Text box will only be validated if any check box is checked in the user control.
I am also not able to find the usercontrols through the main page.

I have successfully loaded fonts that are installed in my system. But now i want that on click on NEXT Button, Label Control's font should change to installed font.
Here's the code to load font:
Dim allFonts As
New InstalledFontCollection
Dim fontFamilies()
As FontFamily = allFonts.Families()
For Each myfont
As FontFamily
In fontFamilies
ListBox1.Items.Add(myfont.Name)
Next
Here's the code for applying font to Label control
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim allFonts As New InstalledFontCollection
Dim fontFamilies() As FontFamily = allFonts.Families()
Dim j As Integer
For j = 0 To allFonts.Families.Length - 1
Label1.Font.Name = allFonts.Families(j).Name
Next
End Sub

I have a ObjectDataSource and a ListView referencing it.
I have created a Templated User Control (see:
http://msdn.microsoft.com/en-us/library/36574bf6.aspx) and placed it in the ListView's InsertItemTemplate
It has one template <ContentTemplate>. Inside that template, I've defined a couple of server controls with their properties = '<%# Bind("colName") #>'.
See below:

I have 3 user controls that I have to load at the same time. They each contain a gridview that pulls data from the database. They are doing a "delay" load of the data so there is a progress bar template that shows that the data is loading however the first gridview fires and loads, then the second, then the third and I need them to all fire at the same time.

The web page I am trying to (slowly) build should allow users to add whichever user controls they want on their page, and order them whichever way they like. This is saved in a database.
So each user could have a different number of controls on the page.
This is the design code, at the minute the user controls are fixed and are not loaded dynamically. They user controls are stored in 'blocks' which look like widgets on the page and can be dragged about to different columns. For each user the layout is stored in the DB i.e. which blocks are in column 1 and which blocks in column 2 etc.
How could I change this so that it can create a 'block' div for each user control returned from the database and put the user control in that block and in the right column?

I am using ASP.Net 2.0 with Ajax.
I am working on a pretty heavy page in an application and the scenario is:
There is a Tab control in the page, having four tabs. These tabs individually consist of different user controls and other asp controls. Most of these usercontrols in turn consist of other user controls. Every user control contains huge javaScript functions which validate them, populate controls and call web services.
What I am trying to achieve is to load only the Tab and its user controls on the page load and when the user clicks on a specific tab, load its contents (User controls) dynamically. Once that is done, I am setting the tab's postback to false to prevent loading it again once loaded.
I tried to achieve this by making the user controls in the other tabs - visible="false" in the markup and loading them from server side on some specific event. But that causes the javaScript functions in those user controls to give errors ('Object expected') when I go to that tab.
If I set the user controls in the other tabs to visible true, then no matter what; the page life cycle goes to each registered control and loads every subsequent control in that web user control which makes the main page slow (on loading and every postback).
The position of the Tab and the inner user controls is fixed. Although I am taking care that no data is populated unnecessarily on the page and user controls on hidden tabs, I dont want the tabs to get loaded altogether unless requested. If I load them on runtime, their corresponding javaScripts start giving errors.. note that I am not generating the controls on runtime, they exist in the page design. I just dont want to load them dynamically

I have an ASP.NET 4.0 application with some simple user controls. The user controls work fine on the design surface (VS.NET 2010), but when they're loaded during application execution, nothing shows up.
Futhermore, the various child controls of the user controls are null when referenced inside the code behind for the user control.
The code behind for the user control executes as expected, but any reference to child controls are null.
It's like ASP.NET is never parsing the ASCX to create the instances of the child controls.

I have an .aspx page with multiple .ascx (User Controls on it). One of the User controls is very slow in loading (calls a very slow webservice for the data.). Now, my question is how to render all the controls on the page (so the User can view those) and have a rotating icon for this control (slow one) (till it loads). I know, I need to bring AJAX into picture, but any clarification on that would help as I will be new to AJAX programming.

I am trying to create my own website management framework similar to DNN/SiteFinity (only a mucho cut down version).
One of the big (but common) features is to be able to dynamically add user controls to provide additional functionality.
I would prefer to use a pre-compiled .NET "Web Application" over a dynamically compiled "Website".
What are the implications of using LoadControl method to dynamically add a user control for a pre-compiled web applications with specific regard to:
Session (preume I am using the stateserver)What happens to all the other users - will they be logged out?
Application pool recycling due to changes to some compilation??
I am not sure I have ever dynamically added a user control to a pre-compiled web applications as I have mainly been using "Websites" so I am making a large presumption that it will work because if the website is pre-compiled, does this mean the dynamically added user control will be dynamically compiled as required even though the site is pre-compiled?
EDIT
I also forgot to mention that the user controls will be outside of the application directory and so won't be published during web deploy - they will be uploaded via another website.

I have multiple user controls on the page that are used primarily for data entry purposes. When a product is loaded, I need to load the product data into all those user controls and retrieve data when I need to save the product. The user controls are not visible to the user directly, instead user would click on a link and the user control will open up in a modal popup.
Currently the way I'm doing this is, I've loaded all the user controls on the page in separate div controls, and showing the modal popup when the link is clicked. I'm sure loading all the user controls on the page is not a good idea. Is there a better way to handle this? I think we can show the markup using JSON with jQuery - but how can I load and retrieve the data using that?

I'm working on a bug in our application and I cannot figure out why this problem even exists. We have a custom DataGrid control that inherits from the standard asp.net DataGrid. In the grid, we have a ButtonColumn as the second to last column. The code for that column is:
[Code]....
The problem is that the "alt" text does not show up at all. There are 2 other images in this DataGrid, and the alt text shows up just fine in those.

First, I would like to apologize, the search on the site wasn't working, so I don't know if I'm missing an existing post or not.
I have a web page that uses a master page file. I am using a third party control from Component One(TabStrip), the tabs are rendered as links on the final page. When a tab(link) is clicked, I need to load the appropriate web user control associated with that tab. Each web user control has its own post backs and methods. I know that I can load the controls on the "SelectionChanged" event of the TabStrip control, but then any postback created by the web user control that is loaded causes the page to refresh and the control was never loaded in viewstate. So, I tried to put my procedure of loading the web user control into the page_init method. This would work, if I could read which link was clicked on from within the page_init method. I tried using a javascript function to run "onclick" of the tabs and within it setting the value of a hidden control. I have verified that the javascript works and that the hidden control's value is getting set correctly. When I get into the page_init method, the value of the hidden control is not readable.
I'm tying to understand the page lifecycle to the fullest, but I don't see what I'm missing here. I know that I need to load the web user controls in the page_init method in order to persist the page as a whole, but how can I get which tab(link) was clicked to know which control should be loaded?

I have been playing around with loading user controls in a CMS style where I can change the position and order. I have come up with this...
[Code]....
It all works fairly well - but I have alot of propertys in my user control code behinds where I could inject values into the usercontrol from my base class.
I like the way I can position usercontrols from the DB, I even added a time and date section where they could be switched on and off per day or time.
If I make every user control access the DAL for the data, it means i will have one select per user control, which means including my bassclass I could have upto 15 selects (visits tot he DB) to make the front page. Though this does not seem to make a performance problem, I was wondering if there was a better way of doing this.
