AJAX Page - Using SetValue

You can set a value to a html element on client from server-side.


input elemets (textbox)



dropdownlist



textarea



radio button
checked / unchecked



Note: The radio/checkbox button can't be set as checked/uncheked using the SetValue method.
You need to set it manually at the end of the callback.

ASPX
<input type="radio" id="radioElement" />
<input type="button" value="Callback now!" onclick="ob_post.post(null, 'ServerSetValueRadio', function(checked){document.getElementById('radioElement').checked = checked;});"/>

C#
public bool ServerSetValueRadio() { /* this will return true if need the radio button as checked */ return true; }
