I have created a master page with a navigation area that contains a Tree View. The two nodes in the tree view have their navigation URL fields set to a different aspx pages. Within the content place holder for each page there is a script manager and an update panel. First.aspx contains a standard gridView control that is bound to a database inside the update panel. Second.aspx also contains a script manger as well as an update panel. Within the update panel is a WebDataGrid bound to a database.
When I execute the code and click on the node for First.aspx, the grid appears and populates without refreshing or blinking the page. When I click on the node for Second.aspx, the WebDataGrid appears with data but the entire page refreshes or blinks. It does not seem to matter what Infragistics control I use in the update panel for Second.aspx, it always refreshes or blinks the entire page when I access the page. If I place a standard Visual Studio 2010 control within the update panel and access the page, the page does not blink.
What am I missing? Why do pages with Infragistics controls cause the page to blink and standard ASP.NET controls do not?
Thanks,
Scott
Hi Scott,
I have asked our developers for their insight on this so we may have a better understanding of why this is occurring.
I hope to hear back from them by Wednesday and I will update this thread once I hear back from them.
I see the blinking you are referring to and I need some more time to research why this occurs.
I will have more information on my findings for you by Friday.
Michael,
Thanks for your reply.
I tried setting the EnableAjax flag to false for the WebDataGrid and the page still blinks.
I'm using Infragistics version 12.2.20122.1007, .NET Framework 3.5 and Internet Explorer 9.
Thanks for posting on our forums!
When using our Aikido controls, such as the WebDataGrid, inside of an UpdatePanel their AJAX functionality should be disabled. You can use the EnableAjax property of the grids, or the EnableAjaxViewState property of our other controls to disable this. Please try setting your WebDataGrid's EnableAjax property to false and let me know if the blinking still occurs.
If the issue still occurs, could you please let me know which build and version of NetAdvantage you are using? It would also help to know what browser and .NET framework you are experiencing this with.
Looking forward to hearing from you.
