Comparable control to FilteredTextBox from ASP.NET AJAX Control Toolkit

[Chen]

Hi
I need to limit the input on all the controls of the page to a certain group of characters.
The input is fed to a banking system that can accept only ASCII 032-0126 with the exception of 23 characters in this range ($, £, @, #, ...).

MS AJAX Control Toolkit's FilteredTextBox  appears to be doing the job with the ValidChars attribute.

Is there a comparable capability for Telerik?

I'd hate to add the MS AJAX  toolkit to my pages as it would increase size and potentially complexity.

Hello Chen,

I guess RadMaskedTextBox  is an option for you. It is an enhanced data entry control that uses a mask to distinguish between proper and improper user input.

Take a look at the following help article for more on this.
RadmaskedTextBox Basics

Thanks,
Shinu.

Shinu, I am not sure I can implement what I need with the RadMaskedTextBox.
Let's say I want the textbox to accept just 'a', 'C', 'Z', '=' and '2'. Just these 5 characters, and they can be in any position in a long string. 

So for example, this is a valid string: CaZ2Z=a
This is not: C3aZ

Is there a way for me to do it  with the RadMaskedTextBox?

Hi Chen,

Another option is to use RegularExpressionValidator with RadTextBox to limit its allowable values as shown in this help article.

All the best,

I understand that a validator can somewhat help here, but my question is very specific.

Does Telerik have a control with a similar functionality to  FilteredTextBox that actually limits characters at the entry stage.

Alternatively is there a javascript function I can use as this limitation is for all the controls on the page.

Thanks again
Chen

Hello Chen,

Another option is to use the RadInputManager and its RegExpTextBoxSetting to configure an ordinary textbox to accept only specific type of input. Other than that we do not have a specific input control that limits input values in such way.

Another common client-side approach for validating is to handle the form's onsubmit event and add there validation logic which will prevent the form from submitting if the input is incorrect.

You the man!

RadInputManager is what I need with the regular expression.
I just set what characters I allow and assign it to all the controls on the page.

A suggested improvement is to add functionality that stops the user from entering characters out of range, rather than validating after blur.

For now it works. Thanks again.

Hello Chen,

Thank you for the suggested improvement.

Glad to hear RadInputManager worked in your case.
