there is a sample code for creating a custom textbox control with built in validation posted here Building ASP.NET TextBox with Integrated Validation And Switchable Input Modes. Inside the code there is a call to Controls.Add(validator) which adds the asp.net validator control to the textbox. when the textbox is used on the page, the validator is rendered to the page although the validator is added to the textbox and not to the page!

View 4 RepliesI have a web user control that represents a simple message box. It is used to display simple messages like "Item has been deleted", or "The item was saved successfully".
On the other hand, I have another web user control that represents the item in the form of an editable form (I made this a user control because this is used in two different pages). I want to embed an instance of the message box user control inside the editable form. I am writing this right after the @Control directive:
[Code]....
Instead of using @Register directives, I register the user controls in web.config and so far this has worked just fine.
With the above markup, the project compiles, but whenever I try to navigate to a page that contains this construct, I get an HttpParseException exception. Furthermore, Visual Studio states that the tack w7rc9:MessageBox doesn't represent a known control.
What am I doing wrong?

How can we use required field validator on User Control in aspx page*strong text*
I have one user control that have one drop down. I am using this control on my page. I want to use required field validator on this drop down.
All I would like to be able to do is include one user control within another! Is this possible? I have spent the last hour searching the internet and it seems that I can't find a single thing.
In classic ASP it would be something like:
<!--#include file="EditProject.ascx"-->
I tried this but no luck!
Parser Error Message:
There can be only one 'control' directive.
Source Error:

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 a modal popup where the 1st control is a dropdownlist, then 2 invisible textboxes and then one visible text box(txt1). All of these have required field validators attached with ajax callout extender.
Based on the dropdown value, the invisible textboxes get visible and the corresponding required field validator controls get enabled.
Now problem is, if i dont enter anything and click on submit, instead of showing error message for the 1st control i.e. the drop down, it is showing message for the visible textbox(txt1).
what i am supposed to do, to display the error messages accordiing to the tab index of the controls?

Thing is that for some reason it doesn't locate Validators. If i add the line - alert(sid) , it will show me all the Id's of the controls inside the GridView except for validators.
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.

How can I get all the textboxes inside a create user wizard control using getElementsByTagName().
Below is my JQuery code:
[Code]....
The above code isn't displaying hint text when the textbox retreives focus.
I think there is something wrong with this getElementsByTagName("asp:TextBox"); , I have also tried getElementsByTagName("TextBox"); , getElementsByTagName(":textbox"); and getElementsByTagName("input"); .
But no one of them gets the textboxes array.
Can anyone tell what will be the correct syntax for getting all the textboxes inside a create user wizard control using getElementsByTagName()?

I have created a web user control I want to change the iframe' src value when the user click on the link but the problem is that I dont have access to iframe inside the page from web user control I think there is a way because my control is in the page they have some relation perhaps I like to find something like this :
[code]...
I 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."
