Firefox Specific Radwindow Issue - Dropdown Selections Not Being Retained In Firefox, But Working Fine in Internet Explorer

[jgill]

I am having what seems to be a Firefox specific issue with a RadWindow and wanted to know if there is something I am missing about how Firefox handles this situation in a RadWindow.

I have a RadWindow that loads a page that dynamically populates the contents of dropdowns based on the selected value in another dropdown, however in Firefox this is not functioning the same as Internet Explorer.

Internet Explorer
The selected item on cboDropdown1 is changed on the selected index change then cboDropdown2 is populated with the applicable values.  When the page refreshes the selected index of cboDropdown1 is retained.

Firefox
The selected item on cboDropdown1 is changed on the selected index change then cboDropdown2.  When the page refreshes the selected index of cboDropdown1 is not retained and the first item in the drop down cboDropdown1 is selected.

The page that loads in the RadWindow originally had a RadAjaxPanel and RadLoadingPanel where the controls were contained within the RadAjaxPanel, but I removed the RadAjax panel to see what occurs in regular Postback scenarios and the same issue occurs in Firefox, but not IE.  I have attached an image of the original page structure.

If I need to add particular code to address this, what would that be and on which page should I add it (e.g. OriginalRegularPage.aspx, RadWindow 1 page, RadWindow 2 page).

Hello jgill,

At this point I cannot tell what might be the reason for the problem, but I believe that it is not related to the RadWindow control - RadWindow is basically an IFRAME and behaves just like one. Just for testing purposes, please replace the RadWindow with an IFRAME and see if the problem persists - this would show whether the problem is related to RadWindow or not.

In any case, it will be best to open a support ticket and to send us a sample project where the problem could be reproduced. We will check it and do our best to help.

This looks like the solution, Firefox is one of the browsers that experiences the problem in the postback in the iFrame.
