combo box datasource values not refreshed.

Hi, We have a DataGrid. I have bound a combo box column with dataGrid.SetGridComboBox method. Then Dynamically based on user selection of another combo box column I have to load the datasource of the original combo box. Here is what I have written: dataGrid[2, 2].CellType = "ComboBox"; dataGrid[2, 2].DataSource = null; dataGrid[2, 2].DataSource = dsEntityClassType.Tables[0]; dataGrid[2, 2].DisplayMember = "Name"; dataGrid[2, 2].ValueMember = "EntityTypeID"; The code compiles well without bugs. But the new datasource is not shown in the combo at 2,2. Thanks and have a nice day :) Help would be greatly appreciated David.

If dataGrid is a GridDataBoundGrid, then you cannot set style properties on a cell by cell basis. See these KB articles on this. http://64.78.18.34/Support/article.aspx?id=560 http://64.78.18.34/Support/article.aspx?id=10351 If you want to dynamically provide the dropdown list for a particular cell, then one way to do this is to use the CurrentCellShowingDropDown.
