Hi Dilip,

That dialog is created by the grid and the grid is responsible or it. You should not be disposing it or setting DisposeOnClose.

Hi .

its workin fine but ,i am setting DisposeOnClose property is True.because i do someting code when application is minimize or we swift one form tab to another form tab..

DisposeOnClose property is True is may be Reason that when i click on

ColumnChooser then it appear at default position and after then it is show  really position(which set via according your code.).

e.Dialog.DisposeOnClose = Infragistics.Win.

.True;

can we stop it(flickering(Column Chooser) )?

Please help me.

Thanks

Dilip

its working fine.

Thanks :)

It looks like the location of the dialog is set internally after the BeforeColumnChooserDisplayed event is fired. So you will not be able to set the location inside that event.

What you can do is delay the setting of the location by invoking a method to set the location, rather than setting it directly inside the event:

        private void ultraGrid1_BeforeColumnChooserDisplayed(object sender, BeforeColumnChooserDisplayedEventArgs e)
        {
            UltraGrid grid = (UltraGrid)sender;
            grid.BeginInvoke(new PositionColumnChooserDialogDelegate(this.PositionColumnChooserDialog), new object[] { e.Dialog, grid });            
        }

        public delegate void PositionColumnChooserDialogDelegate(ColumnChooserDialog dialog, UltraGrid grid);
        private void PositionColumnChooserDialog(ColumnChooserDialog dialog, UltraGrid grid)
        {
            dialog.Location = grid.PointToScreen(grid.Location);            
        }

Please Help me.. it is not work
