Hi Team,

As I am trying use Radalert box to show the validation messages from javascript function. (Earlier we were using normal alert for validation messages).

I am able to get the radalert pop up but unable to see the messages on it as its blank box.

Please advise me on this.

Thanks in Advance



Code :


if (grid.get_masterTableView().get_selectedItems()[0] != undefined) {
        selRequestRowID = grid.get_masterTableView().getCellByColumnUniqueName(grid.get_masterTableView().get_selectedItems()[0], 'REQUESTINFO_ID').innerHTML;
    } else if (!all) {
        radalert("Please select a record", 290, 220, "Alert"); //this is the message want show it on UI
        return false;


As I can see it in debugger mode the line is executing without any error and even I can see the pop up box with my css .

Hello Vijayakumar,

I am sharing a summary of the related support thread for convenience and better visibility from the community. 

The issue stems from having more than one RadWindowManagers on the page and one of them had an empty AlertTemplate.

Using a single RadWindowManager on the page and removing the custom AlertTemplate from it resolves the issue.
