Enable and disable RadioButtonList programmatically
The following asp.net c# example code demonstrate us how can we enable or disable a RadioButtonlist control
programmatically at run time. RadioButtonList is an asp.net list web server control which encapsulate a group of
radio button controls. RadioButtonList control has a built in property to switch between RadioButtonList control's enable
and disable state.
RadiobuttonList control's Enabled property allow us to get or set a value indicating whether the RadioButtonList control is enabled. RadiobuttonList control's Enabled property accept a Boolean value.
If we set this property value to 'True', then it indicate the control is enabled and users can select/check item from it. If we set Enabled property value to 'False', then users cannot select any item from the RadioButtonList and the control goes to disabled state. Typically a disable control appears as dimmed in web browser.
