V9 - Changing form field attributes on the client side

Sandeep Gupta

Hello,

Is there a way to change the attributes of a field on a V9 form using a client side Jscript function?

 

A common functionality we need is to change if field is enabled or disabled based on a selection of a radio button.

Prior to v9, we could use "document.getElementById(elementName)" to get a handle on the form field and change it properties easily

But in V9 it returns an object. The object has "disabled" property but changing the property in a client side script function does not make field disabled on the form.

 

Please help and advise

 

Thanks & regards

Sandeep

Hi Sandeep,

 

Since V9 uses Telerik's ASP.NET AJAX controls, you can try utilizing Telerik's client-side scripting API model in combination with Microsoft's ASP.NET AJAX client-side API to manipulate field properties and behaviors such as enabling / disabling fields.

 

Examples:

 

$find("Text1").editor.enable(); // enables the 'Text1' text field using client-side Javascript

$find("Text1").editor.disable(); // disables the 'Text1' text field using client-side Javascript

 

Hope this helps.

Hi, 

 

I tried the above solution, and my textbox seems to remain readonly.

 

I tried with:

$find("txtName").editor.enable();

 

can attach an example?

 

Thanks alot

Thanks

Does

$find("Text1").editor

is universal way for accessing Telerik client-side objects of RadControls?

 

It looks like it works for ComboBox fields ( $find("Combobox1").editor will give you access to RadComboBox ), but I wasn't able to to access client-side object of RadListBox

You start hacking the client, and you're going to have a bad time....
