include a image in devexpress datagrid

• Add an ImageCollection to yout form and add some icons 16x16 to it.
• Add a column to the Grid for the icons.
• Set the column's fieldName to image (whatever you like).
• Set the column's UnboundType to Object.
• Add a repositoryItemPictureEdit to the column's columnEdit.

All the above can be done in the designer. Then do the following

privatevoid gridView1_CustomUnboundColumnData(object sender,DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e){if(e.Column== colImage1 && e.IsGetData){string someValueFromDatabase =(string)gridView1.GetRowCellValue(e.RowHandle, colOne);if(someValueFromDatabase =="a"){//Set an icon with index 0 e.Value= imageCollection1.Images(0);}else{//Set an icon with index 1 e.Value= imageCollection1.Images(1);}}}

The key here is handling the CustomUnboundColumnData and the repositoryItemPictureEdit.
