since we are using Syncfusion v.184.108.40.206 including the patch 2.1.15 the following
code doesn''t work anymore:
// first increase the rowcount (grid now hast 2 rows)
// indexToStart is 2
gridControlFundAttributes.Rows.Hidden[indexToStart] = true;
gridControlFundAttributes[indexToStart, 1].HorizontalAlignment = GridHorizontalAlignment.Left;
gridControlFundAttributes[indexToStart, 1].BackColor = FISConstants.GridDataColor;
gridControlFundAttributes[indexToStart, 1].Font.Bold = true;
gridControlFundAttributes[indexToStart, 1].Text = allGroupData.Name;
// this statement produces the following error:
// allGroupData is a business object
gridControlFundAttributes[indexToStart, 0].Tag = allGroupData;
the stack trace produces the following error:
Caught an exception:
>>> Object reference not set to an instance of an object.

Any hints, tips, fixes I would appreciate - because it definitely worked before v.220.127.116.11.
Thanks in advance

Exactly what version was the code working for (18.104.22.168 or something else?)?
I tried to see the problem in this little sample using a non-virtual GridControl, and it seems to be working as expected?
I assume your grid is a GridControl? Are you using it in a virtual manner?

The version it was running before was v.22.214.171.124.
Yes, I am using a gridControl in a derived way. It''s used quite often, but in two of x cases it doesn''t work.
And only in that case the whole app crashes.
The derived control overrides just a few OnXXXXXX methods, nothing special. Do you have a guess?
I''m trying to construct a sample app to provide some source

Now I got the problem. The application failed when an object was set as the tag object
in the grid. Recent changes to that object in the Clone implementation caused the failure.
That means when the object''s Clone() method has been invoked, the application failed.
So, this issue can be closed.
Thanks for the help
