I have a webpage that has a RadGrid on it (among other controls) and display a modal window when the user submits data. If the rows on the grid are less than 100 rows it all works fine. But if the row count is greater than 100 (or somewhere around 100, haven't got it to an exact figure) the parent webpage's control etc. all disappear and only once the modal window is closed does the parent window redisplay correctly.
Any ideas?
I am using the following javascript to display the window:
function OpenValidationWindow() {
oWnd = window.radopen('../MarketDataPriceInputValidation.aspx', null);
oWnd.show();
oWnd.set_behaviors(Telerik.Web.UI.WindowBehaviors.Close);
oWnd.SetSize(625, 600);
//Adjust position of validation window
oWnd.MoveTo(162.5, 110);
//Set the callBack function to be called once the user has clicked on a button on the validation window
oWnd.add_close(OnValidationWindowClose);
}
