GGC and FieldChooser - column Read Only

Hi
Is it possible to use modifications  a plug-in utility called Field Chooser, which will help customize the view of a GridGroupingControl based on column Read Only

Hi Gregory, 

Thanks for your interest in Syncfusion products. 

We have analyzed your scenario and created the simple sample with FieldChooser from what we had understood from your scenario. In that sample, the field chooser dialog has been prevented from opening for read only columns in FieldChooserShowing event. Can you please provide us with some more details of your scenario and let us know your requirement(with field chooser and read only columns) clearly? Please refer to the attached sample. 
 
Code example: 
this.gridGroupingControl1.TableDescriptor.Columns["Description"].ReadOnly = true; 
FieldChooser fieldChooser = new FieldChooser(this.gridGroupingControl1); 
 
this.gridGroupingControl1.FieldChooserShowing += gridGroupingControl1_FieldChooserShowing; 
 
void gridGroupingControl1_FieldChooserShowing(object sender, Syncfusion.Windows.Forms.Grid.FieldChooserShowingEventArgs e) 
{ 
    int row, col; 
    this.gridGroupingControl1.TableControl.PointToRowCol(point, out row, out col); 
    GridControl control = e.FieldList as GridControl; 
 
    if (this.gridGroupingControl1.TableDescriptor.Columns[col - 1].ReadOnly) 
    { 
        e.Cancel = true; 
    } 
}

Hi Gregory, 

Thanks for your update. 

We have analyzed your scenario. The FieldChooser is used to add/remove the columns in view of grid control , so  the FieldChooser does not have support for customizing as per your requirement. You can use own context menu to customize the column status. Please refer to the below KB for further references,

Hi Davy,

 
Thanks for the update. 
 
We have analyzed the reported scenario at our end. As per our current support, the GridGroupingcontrol does not has the FieldChooser support for nested tables. So, we have added it to our feature request list and created a feature report. This will be included in any of our upcoming releases. 
 
Please let us know, if you have any concerns. 
 
Regards,
Arulpriya
