    <p>I would like to display a modal popup in code behind once the button is clicked, operation executed and next thing would be to display the modal popup. I have modalpopupextender, popup, button which is set to display:none, so the modal popup does not throw an error. I have imagebutton in a gridview from which I am triggering action in the code behind, and once the action is executed I would like the modal popup to be displayed. So, I've been battling with this issue for the last 2-3 hours and I decided to put a post here and someone might help. This is what I have.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
