I have this GridView that have it's DataSource as a list of previously selected products.
For every item on it, I need to Eval it's ID and load a specifc form that the user must fill, then after that i've got to update the GridView.
I have made those specific forms as User Controls, is this the best approach for this scenario?
If yes, how can I dynamically load them, in a way that I can make queries/postbacks then update back my gridview?
How to load a user control dynamically in a page?
I have a page that contains radioButtons. Each click on a radio button loads a user control (.ascx) in the page.
What I am doing is loading all controls at the same time, but set their visibility to false. When a user clicks a radiobutton I set the visibility of the specific user control to true.
As a result I am loading all the user controls on each postback.

View 1 RepliesI have a tab control on my page and on click of tab user control is loaded dynamically.I need to load the javascript file of that user control dynamically. I don't want to add the reference of my js file on parent page.so in my .ascx page load event i added:
System.Web.UI.HtmlControls.HtmlGenericControl js = new System.Web.UI.HtmlControls.HtmlGenericControl("script");
js.Attributes["type"] = "text/javascript";
js.Attributes["src"] = "../../js/DatesJavaScript.js";
Page.Header.Controls.Add(js);

i want to be able to load user controls and populate them with data from a sql database at runtime based on a status field in my database but im struggling to do this.
my default page.aspx holds the user controls (acts like a container). at the moment i had referenced all the user controls to load up when the page was loaded so:

i then created a procedure which reads from the database the "status field". so if the status field is "pending" then i want the uc:GRLOLApproval control to show up but im not sure where to put this code or how to do it. i want to be abel to load the control at runtime and run this code. in my default.aspx.cs code i have done the following in the page load:

i tried to reference te user control in my default.aspx page by doing: protected GRLOLApproval GRLOLApp; but it wouldnt recognise it because it not been reference in the source file.how do i reference it so that i can read the data from my database and write to the fields in uc:Collectionrequest. (I have exposed the properties in the uc:CollectionRequest that i want to access btw) have been working on this for days now and just cant seem to load the user control or access any properties.

I am working on a project which creates controls dynamically for a form in the page_load event, loads in their current values from the database and saves their values (using FindControl) when the user clicks the continue button. When I added a control statically in the .aspx page and followed their same procedure of loading the value in the page load and saving it on the button press I found that the value would not save correctly. It seems that it wouldn't save because the click event fires after the page_load, so the page_load of the post back reverted the value and the user entered value was not saved.
The strange thing is that by changing the control to be dynamically created just as all the other controls on the page and keeping the loading and saving the same it now works. Even though the page load still creates the control with the old database value. It seems like a very fundamental asp .net feature here but i'm just unclear as to what is going on. I suspect it is to do with the timing of creation and maybe when the view state kicks in.
I want to create a user control that will again contain a user control that will be dynamically generated and can be repeated N times with respect to data present in data table.
View 2 Replieslet say i have Two user control U1 and U2. I have a treeview control T1 U1 include a one datalist. U2 include a one datalist.

can it be possible? or if anyone can guid me how to use single page with multiple user control response each other event.
Is there a way to instantiate and use a usercontrol (.ascx) if given you have its Type (ie. typeof(MyUserControl))?With regular asp.net controls like a textbox or a dropdownlist you can just make a new instance and add it to a controls collection. This doesnt appear to work for User controls. While you can make a new instance and add it to a collection, and have all of its events fire, it will not actually render to the page. Typically you would call Page.LoadControl() with the path to the .ascxThis presents a problem if all you have is its type. How can you get the path to the .ascx to give to the LoadControl method. Ideally I would also like to not have to have a reference to the Page object
View 1 RepliesI just want to call a user control using AJAX and get the rendered html of the control. However, when I try and fetch the control I get the following error message:
This type of page is not served.
Description: The type of page you have requested is not served because it has been explicitly forbidden. The extension '.ascx' may be incorrect. review the URL below and make sure that it is spelled correctly.
Requested URL: /Controls/ClientFormControl.ascx
Is it possible to make this type of page servable, or is there a specific way you need to call it? I know such things are easy in MVC frameworks...
Im working with Sitefinity and I'm developing a Control Designer - however i dont think my question is specific to SiteFinity.
I have a class such as:
public class CaseStudyFeaturedItem : CaseStudySelectorControlDEsignerBase
The class it is inherriting from is itself inheriting from UserControl, like so:
public class CaseStudySelectorControlDesignerBase : System.Web.UI.UserControl {
Within CaseStudyFeaturedItem is it possible to load a template which is an embedded resource and then access the controls on that control?
So essentially, I have usercontrol.ascx which is an embedded resource so has a string like:
mynamespace.myclass.usercontrol.ascx;
And from within CaseStudyFeaturedItem I want to be able to load that usercontrol and then modify the controls (i.e. literals/labels) that are within it?
I created a user control called userCon.asxc.may i know how do i do when i click on button1,then the userCon.asxc will load into panel1?
I checked on internet, but found only those loading the user control to page when execute.What i want is to load user control into panel1 when button1 is click.thanks for reading.
I have a user control that will basically be a header in most of my pages, but not all. I want some code in the user control to be run before the page load event of the page that holds the user control, but the page load event fires before the events in my user control. Is there a way around this?
View 3 RepliesPart 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
