Web Forms :: Unable To Load Ascx Dynamically
Jan 24, 2010
Ive got some custom code that im using to load user controls dynamically depending on the option a user selects from a menu control on the page.
I wanted to create an admin page that can be used to provide a one stop shop to complete all actions within an app im building, (like a template/iframe scenario that loads all selections in a screen on the right)
My code works, however when the user has completed an action sucesfully within one ascx, then selects another from the menu on the left, it wont load the new control, it comes up blank like it hasnt refreshed properly meaning that they have to close down the page and reopen it. (which is very annoying)
My codes below, can someone take a look and see if they can see whats wrong.

I'm developing an ASP.NET application and I'm trying to do the following:
I'm going to have only one ASPX page splitted into two columns. On the left column is going to be a TreeView, and on the right column is going to be something to edit treeview's nodes.
When the user can select a treeview's node to edit on the right column. Depending on the node's depth fields on right column will vary.
I wondering to use ASCX controls and load on right column dinamically using AJAX, for example. Is there a better choice? Can I do that?
I don't want to reload the entire page when the user wants to edit a treeview's node. Maybe I'm going to need an UpdatePanel on the right column to load dinamically ASCX controls, isn't it?

In the master page code behind I added
public ContentPlaceHolder BodyPlaceHolder
{
get { return ContentPlaceHolder1; }
}
and now, in web content form I want to add to this place holder a new ascx control in code behind.
protected void Page_Load(object sender, EventArgs e)
{
if (!User.Identity.IsAuthenticated)
{
LoginRegisterControl lrControl = new LoginRegisterControl();
Master.BodyPlaceHolder.Controls.Add(lrControl);
}
else
{
UserProfile upControl = new UserProfile();
Master.BodyPlaceHolder.Controls.Add(new Button());
}
}
and this doesn't work. If I change this to
Master.BodyPlaceHolder.Controls.Add(new Button());
It works. So the problem is with the ascx user control.

i have two buttons, which point to some onclick-methods in my code-behind file. inside these btn_click-codes i want to start adding pure html-code to my page, which was told to me in this forum having done by using ascx-files. note: there would be no code-behind in case of using the ascx-files.
however i do not see a possibility to load these ascx-files within btn_click-code? how to do?
in order to give you an idea of my html-code i have pasted two of them here:
[Code]....
maybe this is the complete wrong approach (as i.e. i believe that body-tags should not be included in .ascx-code). in this - how to do better?

apologies beforehand for what can possibly be a daft conceptual question. I have an ascx control that has a bunch of ASP labels and buttons in the ascx page and some other public methods and properties in the code behind. When I drop this ascx control in a page it all works fine. I now have a page with a placeholder and I am trying to dynamically create an instance of my ascx control and put it there. I then reference this control in code and while all public methods and properties are available (ie MyControl.TitleString = "Hello";MyControl.DoSomething();) none of the ASP controls are. Rather, they are all null. So MyControl.buttonSave is null, MyControl.LabelTitle is null, etc. Is this by design? Am I missing something? If not, what's the point of being able to create dynamically do this?

I'm developing an ASP.NET application with C# and Ajax.I have a page that holds user controls loaded dynamically. I need to pass some data (integer values and some strings) to the user control that has been loaded dynamically.Now I use Session to pass these values, but I think I can use another way; something like VIEWSTATE or hidden input.What do you recommend me?The fact that I load the controls dynamically is important because controls are loaded on every postback, and I can't store any value on controls.

I have a dropdown list on my homepage which users select a category. After selecting the category, user will fill a form which has related controls to that category in it.
As I have many categories, I just want to have single ascx page and adding controls to it dynamically according to the user choice.
For example: One chose Telephone category, he will face a form having drop down lists asking, what brand? what color? And one chose, book category, he will face drop down lists asking which type? howmany pages?
So 1 ascx must do my work at runtime done as I have alot of categories.
I am going to take these criterias from a database table which has CategoryID and Criteria colomns.
And if I can do that, will it be possible to add field validators to these dynamically created controls.

I have a user control (ascx) which contains a control (hidden field). In the page_load event of ascx, i have the below code:
HyperLink.Attributes.Add("onclick", "JavaScript:return AccessControl('" + hdnField.UniqueID + "');");
Note: The hidden field resides in .ascx file.
I want to access this hidden field at runtime and i have the below javascript function in aspx page that loads the usercontrol.
function AccessControl(hdnFieldId)
{
var ctrl = document.getElementById(hdnFieldId);
alert(ctrl);
I am getting 'null' value in the alert. I tried using 'ClientID' and 'this' instead of 'UniqueId'. I am wondering why this is not working. I am using .net 2.0.

is anybody interesting in share and join to develop callback web controls. My purposes is lower unsynchronized page development cost. I have developed a base class and a set of common controls. Currently, they allowed to be loaded dynamically in a control or ASCX via callback event using sample server side code. Control library code will automatically register javascript and render it on client browser. These controls worked fine in both callback and postback. To load dynamically from an ASCX file.
'ascx1.ascx contain some callback-able controls
Private Function LoadAscx_DuringCallback(Optional ByVal RenderMe As Boolean = False) As String
Dim rt As String = ""
div1.Controls.Clear()
Dim c As Control = LoadControl("~/Test2/ASCX/ascx1.ascx")
c.ID = "ascx1"
div1.Controls.Add(c)
If RenderMe Then rt = CallbackManager1.RenderControlHelper(c)
Return rt
End Function
Or to load dynamically as a control
'c is a callback-able TextBox
Private Function LoadControl_DuringCallback(Optional ByVal RenderMe As Boolean = False) As String
Dim rt As String = ""
div1.Controls.Clear()
Dim c As New ACT360_CallbackControls.ZYH.TextBox
AddHandler c.KeyUp, AddressOf TextBox_KeyUp
AddHandler c.GetFocus, AddressOf TextBox_GetGocus
div1.Controls.Add(c)
If RenderMe Then rt = CallbackManager1.RenderControlHelper(c)
Return rt
End Function

I have to build a few ascx partial views in my MVC applications to encapsulate re-usable functionalities as well as archive SOR and SOC. However, I encountered challenge how to encapsulate the business logic that drives MVC ascx views.In webforms, the code behind of an ASCX control can handle a button click event and browser still shows the same page with only one postback. How can I archive the same thing in MVC? When ~/Address/Edit/2 includes an ascx partial view with a button on it that calls another MVC action - let's say ~/ShareController/CommonAction - what is the best way for the CmmonAction to return to the very same view that includes the ascx file?Perhaps I am missing a common pattern in MVC web development?

I am having difficulties how to construct my question, but if I have to put it simply the situation is that I have categories of products. I have an aspx with a repeater on the left that lists the categories. And I want the products to be listed on the right. Category number is variable so I made an ascx with a DataList in it. When I try to do foreach category, ascx = new ascx(); then the DataList within this ascx control is null.
ps: what I want to do is to preload all the products (thre is not much) and hide the divs and fadein fadeout them using jQuery when a category div is clicked.
rightnow it is using jQuery.load(); and I don't like how the images load, cuz they download from top to bottom. Progressive gifs alsdo not an option. site demo is here [URL]

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:
[Code]....
[Code]....
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:
[Code]....
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 have UserControl that has asp control(<asp:Button runat="server" ID="btn" />) and I want to render it.
I tried 1
[Code]....
It doesn't works because it says that each control that has runat="server" must be in Form.I also tried 2:Because loader.Form is null, I create HtmlForm and added the ctrl to it and then added HtmlForm to loader's Control, BUT it says that it has 2 HtmlForm. So, instead I "injected" HtmlForm to loader like this
[Code]....
Now no error is occurred, BUT StringWriter is empty. don't tell me to add Page to solution and override OnRender. I want to do it as I mentioned above.
