RadGridView Rows Cut Off By Parent Grid

[James]

I have some RadGridViews in a Grid with some other controls,once I add enough rows in the GrdSupplyAirAnalysis data grid the last row(s) start to cut off.  If I have 125 rows or more several rows are completely cut off.  The scrollbar has no effect, it doesn't think that it is necessary as it is disabled with set to visible.

Hello James,

I highly recommend having a look at the Tips and Tricks article of our documentation for more information on the matter.

As stated there, you should avoid placing RadGridView in controls/panels which will measure it with infinity as in such cases, virtualization turns off. For example, ScrollViewer, StackPanel and Grid with Row.Height=Auto or Column.Width=Auto will measure with infinity.

In your particular case, removing the ScrollViewer and setting star-based or fixed widths and heights for the rows and columns containing the GridViews should produce the desired behavior and also boost performance.

I hope you find this information helpful.
