Commit() error while using PopupControlExtender of AjaxToolKit

Error :
The control '' already has a data item registered.
Parameter name: control

Solution:

The above error occurs with the PopupControlExtender of AjaxToolKit. This occurs when the commit() function of the control is called. The reason is because the commit() might be called twice or the event where the commit funtion is called would be fired twice. ie, the commit() fires before the popupcontrolextender is closed.

To solve this instead of calling the commit() function, assign the value directly to the target control and call the cancel() of the popupcontrolextender. Like,

Targetcontrol1.text = sourcecontrol1.text;
popupcontrolextender.cancel();
