Hi there,
is it possible to disable Row details unload while the user scrolls through the grid ?
With one row being expanded and showing row details, all works fine, except when the user scrolls down and up again.
I'd like to save the time to handle unload/load code, because inside RadGridView we have a tab control with several tabs.
Best regards

Hi Oliver Abraham,

The behavior you get is the expected one. RadGridView is a virtual UI component and its virtualization is turned on by default. When you scroll up and down the rows are being recycled including the details. The only way to disable the unloading of RowDetails is to turn off the row virtualization through setting EnableRowVirtualization/EnableColumnVirtualization to False.
Will you verify how this corresponds to your needs?

Hi Vanya,
thanks for your quick response. In fact it helps, but the performance is so poor that I can't use it. The user would have to wait about a minute until 1200 rows in 20 columns are loaded.That's one reason for UI virtualization, I know. With virtualization turned on, the delay is only some seconds.
Nevertheless, thanks and best regards
