MovingColumnsEvent in GridGroupingControl

[Jonathan Urban]

We can move columns in a GridGoupingControl to change the columns index.
it exists an event to catch this action?

Try handling the grid.TableDescriptor.Columns.Changing/Changed events. Check e.Action to see what the change is.

[Jonathan Urban]

It doesn''t work with my grid.
Here is my source code. Please Clay, can you tell me, where is my problem?

What version of our library are you using?

With the latest code, in your sample, your messagebox appears when I move a column to another position in the grid. Now if I drag a column to the groupcolumndroparea, then the event is not raised. To catch grouping/ungrouping a column, use:

this.gridProtokoll.TableDescriptor.GroupedColumns.Changed

I use the version 3.2.1.0 of Essential Studio.

I tried it with 3.2.1.0 as well (using .NET 1.1). Here is apicture of what I see after moving a column. http://www.syncfusion.com/Support/user/uploads/colmoved_6769f2e2.zip

Are you moving columns or grouping columns? If grouping columns, you have to use the event I mentioned above.

[Jonathan Urban]

I''m sure I have the right version because this event works with the developper sample Grouping/Filterbar.
And my .NET version is v1.1 too with SP1.
That''s strange...

Yes, I am moving columns and not grouping columns.
Have an solution?

You are using the exact sample you sent me, correct? This is strange as that sample works for me.

If you look at the picture I sent you, in the background, there is the output window. This shows exactly the assemblies that are being used as the sample is run. Can you check your output window and compare your assemblies with teh ones shown in that picture to see if there is a difference?

Seems the same.

What columns are you trying to drag. When your application comes up, I mouse down on the Kunden header and drag it to the left of RTF_Text. Are you doing something different?

No, I make the same action that you, but there is no result (as any column header).

I tested this apllication on another station but there are the same problem: Event isn''t cathed...

Why if I catch the same event on your sample application Grouping/filterBar, it works?

[Administrator]

I know what the problem is. :)

When I opened your sample, I first looked to see what you had done. I looked in the form''s constructor and for a Form.Load event to see what code you had there and what events you were subscribing to. When I didn''t see anything, I opened up the designer generated code and checked there and saw your ColumnChanged event code. Since I was going to add a GroupedColumnsChanged event as well, by reflex, I moved that event subscription line to the constructor after the InitializeComponent call and also subscribed to the GroupedColumns.Changed event as well.

This is what allowed my code to work and yours not to work. The reason is that when the designer subscribed to the Columns.Changed event, the Columns had not been instanciated yet. When they were later instanciated, a new object is created and the earlier subcribed event was lost.

So, try moving the subscription code into the constructor or Form.Load to see if this works for you.

Yeyeye !!! Good job Clay, it was exactly my problem.
Now, I never will edit the automatically generated code ... ;-)
Thx very much !
