I have a large application with multiple forms and multiple igrids. On one form I have an iGrid - let's call it iGrid1. On a second form I have iGrid2. On the first form, I have a handler for the CellDoubleClick events coming from iGrid1, and initially it works fine. However, if I go over to the second form, do some stuff in iGrid2 (which could include refreshing the data in it) and then go back to iGrid1, now double-clicking doesn't work (i.e. the event isn't firing, so the handler isn't executing). So, something that is being done in iGrid2 is affecting iGrid1. I've been trying to track it down, but without any luck. Any ideas for how to find the problem? It's a Visual Studio project, and I have stepped through the code in the debugger, but I haven't seen anything unusual happening. I'm not even sure what to monitor - is there some global setting for enabling/disabling double-clicking? I've tried watching whether this goes from true to false:
Me.GetStyle(ControlStyles.StandardDoubleClick))
But it stays true. So, is there something comparable (i.e. a global setting) in iGrid?

We do not use any special processing of the double-click event. It looks like this


Can you reproduce this behavior in a brand new project and send it to us for the further consideration?

Thanks Igor. We've narrowed it down a bit further and have a test app for you.

When the iGDropDownList control is set as the CellStyle.DropDownControl and then selected, double-click functionality appears to stop working.

The attached test app illustrates this, double-click in the 1st iGrid works until the drop down is selected within the 2nd iGrid.

Oh, sorry - I did not know that you are still using the v4.5.0. This problem was fixed in the v4.50 build 0022 released on Sep-24, 2013. I'll send you the instruction how to obtain the updated full version in email.
