GridGroupingControl RowHeader decoration conflicts with errorProvider


In my gridGroupingControl I'm using the error provider functionality to indicate an error in the row header.

Basically the red dot appears in error case but it is "hidden" by the black arrow that indicates the selected row (I see the arrow with a red circle around it instead of the red dot with the exclamation mark).

How can I disable the black arrow that indicates the selected row (In my case it is not needed)?

Hi Karuppasamy C,

Thanks for your response.
I know the Studio sample. In my scenario I set the properties that the user can select only complete data rows (not single cells) and also can't modify values (selection only). When the selection is changed I check the data if they are valid for the current context and set the error provider if not.

I attached a small example with my settings and the described problem. 

Thanks for your help,

Hi Philipp,

Sorry for delay in replying.

You can handle "TableControlPrepareViewStyleInfo" event and achieve this behaviour.

Here is the code snippet:

 void gridGroupingControl1_TableControlPrepareViewStyleInfo(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlPrepareViewStyleInfoEventArgs e)
            if (e.Inner.ColIndex == 0)
                e.Inner.Style.CellType = "Header";

Please let me know if you have any concerns.
