Hi Driss,
Are you looking for something like having a seperate column for +/- cells and the record fields.
Attached is a sample which illustrates this.
Data Source for the Grid:
--------------------------
Use the NWind database in App_Data Folder for this sample to work.
Configuring the Grid:
---------------------
There is no direct way to acheive this by setting some properties , though you can acheive this by having a "Unbound Column" where the +/- will be shown. I named that Unbound Column as "Level" .
The look and feel of the grid is pretty basic in this sample, but can be customized in any way you want.
Please let me know if you need furthur assistance.
Thanks for choosing Syncfusion products.
Regards,
