set_value() method does not work

[adi]

Hi,

I have a RadTextbox and I'd like to set the value with javascript. Here is my code:

            var textbox = $get('<%= RadTextbox1.ClientID%>' + '_text');
            textbox.set_value('Test');

But I get an error message Object doesn't support this property or method and if I look in detail I can't find any method like set_value in my object on textbox. I use the last Asp.Net Ajax Controls version.

 I'm looking for help similar to this as I update the value via Javascript and with a normal ASP textbox it updates correctly but with an AJAX enabled RadTextbox it doesn't...

I figured a way around it by setting textbox_value.value = "My Text" but the postback doesn't fire. Grrr!

Hi ,

$get will is alias of document.getElementById, thus $get('<%= RadTextbox1.ClientID%>' + '_text');   will return html element that is actual editable element in RadTextBox

To get reference to RadTextBox client object and to be able to use client API you should use the code below:

var textBox = $find("<%=RadTextBox1.ClientID %>");
textBox.set_value("my value");

Hi All,

I too was just having the issue where the $find returns a null value.  To save other people time if they find this and want to know what to do, remember to put the $find for the textbox in the page load event.  Mine was running before the page was 100% loaded, as such the control hadn't rendered properly yet.

Cheers,

Jon
