During interrogation, the Selected Web Control property grid on the Web tab displays the properties for the browser, frame or control currently highlighted under Web Controls. For example, this example shows the properties displayed for a Link control:

While the application is open in the interrogator, you can change the properties listed in the Selected Web Control properties grid. For example, if you select a link from the application by highlighting it under List Web Controls, you can change the destination for the link. You can modify any of the enabled properties displayed in the Selected Web Control grid while the application is open in the Interrogator.

Also, while the application is open in the interrogator, the properties displayed in the Selected Web Control grid can also be seen and will be the same as those listed in the Properties tab for controls that have been interrogated and are matched. Once you close the interrogator, the properties listed in the Properties tab show only those properties directly accessible to Studio.
