is populated with data and you update a certain cell/row, the grid will update its layout. The more edit operations occur, the more visual updates will be performed. This will inevitably affect performance. In such cases, it is good to use Begin
in order to reduce the visual refresh of RadGridView
to one time. However, it is not recommended to use it when setting the DataSource
for example because in the Begin
block, the notifications in RadGridView
will be suspended.
A possible solution for improving loading hierarchical data, is using the load on demand approach. Please refer to the following help article: https://docs.telerik.com/devtools/winforms/controls/gridview/hierarchical-grid/load-on-demand-hierarchy
Note that most of the forum threads are reviewed by Telerik representatives and sometimes we address the questions asked by our customers in the forums as well. However, a post in the forum doesn't guarantee you a response from the Telerik support team. Moreover, threads are handled according to license and time of posting, so if it is an urgent problem, we suggest you use a support ticket, which would be handled before a forum thread. Thank you for your understanding.
I hope this information helps.
