Oct 4, 2010is it posible to add client side functionality to a custom server control in vb.net?i am looking at msdn library and there is no code for vb :/ http://msdn.microsoft.com/en-us/library/aa719700%28v=VS.71%29.aspxI fount this on MSDN Library Adding Client Capabilities to a Web Server ControlWhat i'm trying to do is to add some client functionality to my control, so that you can get or set some properties/values on client side. From the above link i see that this is doable with Ajax Server Control, but i don't have it, i have Custom Server Control. Can i do this with Custom Server Control and how?

Custom TextBox Control With Built-in Client-side Validation?
Jan 30, 2011I have a textbox in my application which has multiple validation on it e.g. RequiredFieldValidator, RegexValidation and CustomValidation. My page has several similar textboxes. So I just copy-paste and change id and controltovalidate properties and it is working.
Since similar tbxs are going to be used on another page as well, I think it would be nice to create my own custom TextBox control with built-in validation.
Here are two approaches I have found and tried:
1: Implement from IValidator perform my custom validation in Validate Method. As shown here: Self-Validating TextBox But it does not show how to implement client-side validation.
2: Create custom control that derives from TextBox and add asp.net built-in validators I need. As shown here:Custom TextBox. I tried the code and it works server/client side.
I like the first approach but don't know how to implement client-side validation. I know I need a client-side js function. I can do that. I know how to include my js file using Page.ClientScript class but don't know how to integrate all together and make it work.
I can create a UserControl or the second approach above but for now I am specifically looking to learn and implement client-side validation from custom control.

Custom Server Controls :: Category Attribute Of User Control Property Does Not Work Correctly In Categories Tab
Aug 19, 2010I have a User Control (ascx) and a property which a want to display in my categories tab in Visual Studio in the category named "Styles".
[Code]....
And here is the problem: Actually I do not need a get, because I only have to set the property (write only property). But when I omit the get, the property is displayed in the "Misc" category in the categories tab in Visual Studio. Only when I code the get as well, then the property is displayed correctly in the "Styles" category in the categories tab in Visual Studio.
Does anybody know why? How can I display the category correctly only with set?
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?
Removing Readonly Attribute From Textbox Using Client Side Code
Mar 5, 2010I have a multiline textbox that by default, is set to ReadOnly. I would like a button on the page to change the control to allow it to be edited. I would like this code to run on the client side because the page renders slowly and I'd like to avoid the post back.
The problem I'm having is the javascript code that I wrote to remove the readonly attribute appears to have no effect. I posted a stripped down example that illustrates the problem for your review.

Forms Data Controls :: Set Attribute In Custom User Control And Keep Getting Zero?
Jul 30, 2010[Code]....
I am having a problem setting the SystemObjectRecordID attribute of my custom control inside a repeater. Currently, the value winds up as zero in the database. Things I have checked:
1) The datatype of the DB column (bigint) and the datatype of AlertId (long) and the datatype of the getter/setter SystemObjectRecordID variable (long) match.
2) If I set '<%# ((Alert)Container.DataItem).AlertId %>' to the Text attribute of a label I get the expected results. So, it has something to do with my custom control and specifically how data isbound to the SystemObjectRecordID attribute.
Now, going to the server, below is what I have for databinding (The page is Default.aspx.cs and the namespace is Company.ProjectWeb.Profiles):
[Code]....
Currently I am trying to pass the value received from a literal (because I know that the values are received as expected here) to the SystemObjectRecordId object. Still isn't working. I am still getting a value of zero when I set a breakpoint and look at the value of SystemObjectRecordId in the codebehind of my control:

Web Forms :: Client Side Custom Validator Changing Textbox Values?
Mar 19, 2010I've been working on a task to add a validator to compare the values of two text fields in a ASP.NET 1.1 application.
It uses validators already, so the best approached seemed to involve a CustomValidator. I was inspired by the following example:
[URL]
I got the server side validation working - now I'm trying to add some client-side validation but I'm having a strange issue.
When I click in either of the two text fields, the value of the txtFinalGrade field is overridden to either "true" or "false". I've been having a tough time tracking down the code that's causing this. I tried using the IE Developer Toolbar to trace the script - as well as FireBug in Firefox (though this is an IE-only app) and I'm still trying to figure out what's causing this to happen.
Since I think this is a JavaScript issue, I'm posting that part of my code:

Anyone have ideas of things to try? Anyone have similar issues with textboxes being set to true/false when working with custom validators?
Custom Server Controls :: Custom Validator Client-side Validation Cannot Work?
Jan 13, 2010I've been trying to get a custom validator component working that ensures at least one checkbox from a checkboxlist has been checked.

Basically, I compile the below code into a DLL and add it to my bin folder.

View 4 RepliesAdd A Custom / Namespaced XHTML Attribute To A Web Control Declaratively?
Aug 24, 2010Normally, unknown attributes of a webcontrol are passed through to to the rendered element in the browser. So the following works.
<asp:label runat="server" Text="Label Text" helpId="101" />
However, if you use a namespaced attribute like the following
<asp:label runat="server" Text="Label Text" myNs:helpId="101" /></div>
The attribute is not rendered to the client, even when the custom namespace is declared in the html element like: <html xmlns= [URL] Does anyone know of a way to get this to render to the client, without having to use a custom control. A module or other globally "pluggable" solution would be acceptable.
