Hi Ambuj,
According to my understanding, you have a PopupControlContainer associated with a button placed within a XPTaskBarBox. When the PopupControlContainer is displayed, it gets hidden when clicked on the form, but does not do so when clicked on another XPTaskBarBox. Please refer to the
test sample attached here, that shows how this can be done. If I have not understood your problem correctly, kindly modify this sample to show the problem and send it back to us so that we could investigate this issue here. Also let me know the version of Essential Suite that you are using. We appreciate your cooperation, and interest in Syncfusion products.
