Hi, using the GDBG (v4.2.0.37) i noticed the rowenter event is being fired when the grid loses the focus. Why is this and how can i prevent this?

Hi Edward, It will be helpful, if you provide us more details / modify the attached sample to reproduce the issue. The following sample demonstrates the behaviour without any issue. Sample : RowEnterIssue Thanks and regards, Madhan

Hi Madhan, Thanks for your response. After migrating our application from grid v1.6.1.8 to v4.2.0.37 i noticed that the RowEnter event of the gdbg was being triggered when the gdbg loses the focus. After some debugging/comparing yesterday i noticed that the newly created grids on a form has the property UseListChangeEvent=True while for existing grids this is set to False. If UseListChangeEvent=False and the datasource of the gdbg is a datatable the RowEnter event is triggered when the grid loses the focus, but not when UseListChangeEvent=False. For an arraylist as the datasource the UseListChangeEvent has no influence on the RowEnter event being triggered. It’s always triggered. I attached a VB sample (VS2005) to demonstrate this. I assume this is not the intended behavior of the grid. (or is it?) Is there a way to prevent this issue? Best regards, Edward

Hi Edward, Here is the sample which demonstrates a way to avoid this problem. This is achieved by suspend / resume binding when leaving and entering the grid. I hope it helps to solve your issue. Sample : RowEnterIssue02 Best regards, Madhan
