The Grid control hangs when it tries to set selection to another grid cell after a validation error

created 9 years ago

Hi,

I think it hangs up on the call to DevExpress.Xpf.Grid.Native.DataViewBehavior.IterateCells(). Inside it, startIndex will be set to GridControl.NewItemRowPosition and the endIndex will be set to either 0 or some positive integer. I have attached a sample project.

Replication steps:

  1. Add a new invalid row by specifying a value (integer) only on the "Number" column.
  2. Commit the new row changes by selecting any commited row.
  3. While the new row still has errors, quickly click between two cells of a commited row. (e.g. Click Row1 Cell1, Click Row1 Cell2, Click Row1 Cell1, Click Row1 Cell2, Click Row1 Cell1, Click Row1 Cell2 …)

        Hello Earljon,

        Our developers are working hard to find the cause of this problem. However, I cannot provide you with an exact date when this issue will be resolved. You will receive an e-mail when the status of this issue is changed. As an immediate workaround, you can set the GridControl.SelectionMode property to the SelectionMode.Row value.

        Thanks,
        Elliot
