[Solved] selecting a combobox column value with mouse triggers a mouse leave for radgridView.

[Ole]

Hi,

I have a rad gridview (x:Name="gridviewSignals") with a combobox column  and a mouse leave. On mouse leave I do a commitedit on the gridview. I do it like this so I am always aware of validation error in the gridview, before some other events happen that might put the gridview out of the UI.

However when trying to select a value from the combobox column dropdown list triggers the mouse leave on gridview, resulting in closing the dropdown list. So even through the combobox is part of the gridview selecting a value in the ddl with your mouse will trigger a mouse leave on grid.

Is this exspected behavier ? ,  Any idears for a work around.

Hi Ole,

Generally, this would be the expected behavior since the mouse goes to another element - a RadComboBox. If you want to get all the validation errors immediately, you may handle the CellValidating or CellValidated events.
