EBS.EntityBase.DAL.FM.tbl_Budget_Set objtbl_Budget_Set; objtbl_Budget_Set = new EntityBase.DAL.FM.tbl_Budget_Set(); this.grdtbl_Budget_Set_Detail.DataSource = new BindingList((objtbl_Budget_Set.tbl_Budget_Set_Group).ToList()); I was tried to do with the above code. But the problem is not solve

I am working with entity model (Dot Net 4) as datasource. For Infragistics.Win.UltraWinGrid.UltraGrid I use a Master table and the table has 1 child table and that child table has also another child table. I can see the existing data in the grid. Master data (Band[0]) can enter in the grid but when I tried to enter new row in child table then the error “Unable to add a new row. Underlying dataSource does not support adding new rows” showe.

Please, Someone help to come out from this issue.

Hi,

I'm not familiar with SQLHelper. What is the DataSource of your grid?

Modifying the data in the grid will only modify the local data source. The grid does not have any interaction with the back end. So when you say editing the grid doesn't affect the table, are you talking about the data source or the actual back end (the database)?
