question to use RepositoryItemPictureEdit in gridView - and nullText or standard-text

Question

Hello
I have question to gridControl/gridView:
I'm using the gridView with images in the datasource (datasource is a bindingsource, and the data comes via entity-framework). With this code, i set the image-properties in the gridControl:

	[C#]
......
......
           if (checkEditMitPatientenFoto.Checked)
            {
                DevExpress.XtraEditors.Repository.RepositoryItemPictureEdit picEdit = new DevExpress.XtraEditors.Repository.RepositoryItemPictureEdit();
                picEdit.SizeMode = DevExpress.XtraEditors.Controls.PictureSizeMode.Zoom;
                picEdit.CustomHeight = 40;
                picEdit.NullText = string.Empty;
                
                gridViewSearch.Columns["patientenFoto"].ColumnEdit = picEdit;
                gridViewSearch.Columns["patientenFoto"].MaxWidth = 40;
                gridViewSearch.Columns["patientenFoto"].Width = 40;
                gridViewSearch.OptionsView.RowAutoHeight = true;
            }
            else
                gridViewSearch.OptionsView.RowAutoHeight = false;
...
...

This works fine - but not all rows have an image in the database; and there is in the row with no image a standard-text or a null-text in the image-column. You can see this in the attachment....
But i set the "picEdit.NullText = string.Empty".....so it must be an other property or an other option.

Please can you give me a clue, how i could delete this standard-text, if no image-data is in the row??

Many thanks in advance for your help & best regards
Michael

Hello

I have found the solution / or a workaround:

I set the "nullText"-property to "space" and not to string.Empty or null !!!

	[C#]
DevExpress.XtraEditors.Repository.RepositoryItemPictureEdit picEdit = new DevExpress.XtraEditors.Repository.RepositoryItemPictureEdit();
                picEdit.SizeMode = DevExpress.XtraEditors.Controls.PictureSizeMode.Zoom;
                picEdit.CustomHeight = 50;
                picEdit.NullText = " ";
                gridView.Columns["PersonenFoto"].ColumnEdit = picEdit;
                gridView.Columns["PersonenFoto"].MaxWidth = 50;
                gridView.Columns["PersonenFoto"].Width = 50;
                gridView.OptionsView.RowAutoHeight = true;

Now i saw no text in the image-column, if no image-data comes from the datasource.

Best regards
