Splitter, Resizing, and Usability

[terrysmith]

Hi,

I've tried using the RadSplitter with both VisibleDuringInit=True and VisibleDuringInit=False and neither one are producing acceptable results.

As an example, one of our pages has a left pane for navigation and a right pane for different content. The content I'll use as an example is a Telerik grid with 10 rows and 6 columns, sized to be 100% width of its container. When VisibleDuringInit=True the grid first appears as "collapsed as possible" and then redraws itself to 100% width. It's very flashy and ugly. Clicking different content in the navigation pane repeats this flashy behavior over and over.

I know the above is the point of having the VisibleDuringInit property; however, when I set VisibleDuringInit to True each navigation click results in a mostly blank screen 2 seconds (almost 3 seconds sometimes) before displaying everything. This is not acceptable either. It makes our application appear very slow.

Is there anything I can try? We would really like to use the split in many places in our application but neither of the above are acceptable to us.

Thank you,
Terry

Hi terrysmith,
In this case, I can recommend the following:

1. We will release a SP next week, please update your version to that SP. We have made some changes to VisibleDuringInit functionality of the RadSplitter and now it loads faster when you have VisibleDuringInit=false and a lot of content in the RadPanes. In case you need it earlier, you can download our latest internal build from http://www.telerik.com/account/latest-internal-builds.aspx.
2. You can ajaxify the navigation control in your left RadPane to update only the RadGrid in the right RadPane - you can use RadAjaxManager (http://demos.telerik.com/aspnet-ajax/Ajax/Examples/Manager/FirstLook/DefaultCS.aspx) for this purpose.

Thanks, I'll wait for the SP.
