Hi Sathish,
To assign the value in a Combobox cell, you need to set the cellvalue property of the Combobox cell in grid. Here is a sample code snippet.
this.gridControl1[4, 2].CellType = "ComboBox";
this.gridControl1[4, 2].ChoiceList = sc;
this.gridControl1[4, 2].CellValue = "Two";
Here is a sample.
Thanks,
