Hi

Is there any documentation on using this feature (I'm assuming this will allow us to show some animation whilst the grid is loading data)?

Hello Allan,

Generally the loading indicator will be shown automatically when the grid DataLoadMode is set to "Asynchronous". You can check this demo for more info:

Kind regards,

Thanks for the reply.

This is working ... however, it seems to freeze for a few seconds just before it shows the grid (I assume thats because the UI thread is busy drawing the grid, and the animation cannot continue). Is there any way to prevent this?

Also, in the demos the animation shows when grouping is taking place - it doesn't work when I do it, is there another flag to set for grouping animation?

Hmm .. looks like the internal build from 6/12 has fixed the grouping / sorting issue.

Further to my response on the 6/12 build .. that was not what fixed it.

I made the grid part of a user control.

When I have the following

<UserControl>
    <StackPanel>
        <RadGrid>

I don't get scrollbars, animation on filter / unfilter / group / sort, etc. It is also much much slower.

When I have the following

<UserControl>
    <Grid>
        <RadGrid>

The problems listed in bold go away.... bizarro.

Hello Allan,

There are some problems with StackPanel that we are trying to address but for now you could try using the Destructo-Beam workaround that I have mentioned here . Basically it involves subscribing to the SizeChanged event of the parent StackPanel and using the actual size of panel as a size for the grid.

Hope this helps.

Best wishes,
Milan
