Hi there,

I need to change the Data Source for Combo Box Cell in every row. For that i am writing like this but it is not working
                    var style = this.griddataBoundGrid[griddataBoundGrid.CurrentCell.RowIndex, 8];
                    style.DataSource = dt;
                    style.DisplayMember = "Name";
                    style.ValueMember = "cmp2";    
and another method 
                    GridCurrentCell cc = griddataBoundGrid.CurrentCell;                    
                    griddataBoundGrid[cc.RowIndex, cc.ColIndex].ResetDataSource();
                    griddataBoundGrid[cc.RowIndex, cc.ColIndex].DataSource=dt;
                    griddataBoundGrid[cc.RowIndex, cc.ColIndex].DisplayMember = "Name";
                    griddataBoundGrid[cc.RowIndex, cc.ColIndex].ValueMember = "cmp2";

both the functions are not working, there is any other way to do this.

Hi Carleone Pratap,

Thank you for your interest in Syncfusion products.

We would like to suggest you by using GridComboBoxCellRenderer in ‘CurrentCellShowedDropDown’ event you can change the Datasource for the ComboBox cell. We added a code snippet below for your better understanding.


void gridDataBoundGrid1_CurrentCellShowedDropDown(object sender, EventArgs e)


                        GridComboBoxCellRenderer renderer = cc.Renderer as GridComboBoxCellRenderer;

                       renderer.ListBoxPart.DataSource = dt;

                       renderer.ListBoxPart.ValueMember = "cntry_Id";

                       renderer.ListBoxPart.DisplayMember = "cmp2";


 Please let us know if you have any further concerns.
