Asp.Net Postback Not Happening In Jquery UI Dialog
Suppose there is having a div with one button inside.
When we try to popup the div using Jquery UI dialog and
try to click the button on dialog, then the postback doesn't happen.
This is because, the Jquery Dialog take the div out of the html form.
So the controls will not be available on code behind.
For Resolving this Issue, we have to append the div back to form.
Please append the above code inside the dialog code.
By this, we are appending the div back to form.
This will resolve your Issue.
