I’m having an issue when I initialize my data grid. I use a datable to populate the combo box in the grid. The problem is that when I click on the dropdown arrow on the combo box, the items from the datable are not displayed. The table does have values and it seems to bind to the combox box correctly but the values are not there. Below is how i initialize the combo box:

td.Columns["STORE_NBR"].Appearance.AnyRecordFieldCell.CellType = "ComboBox";

td.Columns["STORE_NBR"].Appearance.AnyRecordFieldCell.ShowButtons = GridShowButtons.ShowCurrentCell;

td.Columns["STORE_NBR"].Appearance.AnyRecordFieldCell.DataSource = ieDS.Tables["Store"];

td.Columns["STORE_NBR"].Appearance.AnyRecordFieldCell.DisplayMember = "STORE_COL_NUMB";

td.Columns["STORE_NBR"].Appearance.AnyRecordFieldCell.ValueMember = "STORE_COL_NUMB";

td.Columns["STORE_NBR"].Appearance.AnyRecordFieldCell.DropDownStyle = GridDropDownStyle.AutoComplete;

td.Columns[InvErrConstants.HDR_STORE_NBR].Appearance.AnyRecordFieldCell.HorizontalAlignment = GridHorizontalAlignment.Left;

Hi Rocko,

I am not able to reproduce this problem in the below sample that uses the same property settings that you have used for combobox setup in the GridGroupingControl.

Here is the sample download link

Are you seeing any issues with the above sample? Let me know if this helps.

Thanks for using Syncfusion Products.
Have a nice time.

I have a work around for the problem. Essentially I’m copying the table from the dataset into an data table which I create, then copy over the data and bind it to the combo box(example below). It's obvious that there is a setting in my original dataset that’s not allowing the binding to happen. Any ideas what may cause this in my dataset?

DataTable tempStore = ieDS.Tables["store"].Clone();
tempStore = ieDS.Tables["store"].Copy();

td.Columns["STORE_NBR"].Appearance.AnyRecordFieldCell.CellType = "ComboBox";
td.Columns["STORE_NBR"].Appearance.AnyRecordFieldCell.ShowButtons = GridShowButtons.ShowCurrentCell;
td.Columns["STORE_NBR"].Appearance.AnyRecordFieldCell.DataSource = tempStore;
td.Columns["STORE_NBR"].Appearance.AnyRecordFieldCell.DisplayMember = InvErrConstants.STORE_COL_NUMB;
td.Columns["STORE_NBR"].Appearance.AnyRecordFieldCell.ValueMember = InvErrConstants.STORE_COL_NUMB;
td.Columns["STORE_NBR"].Appearance.AnyRecordFieldCell.DropDownStyle = GridDropDownStyle.AutoComplete;
td.Columns["STORE_NBR"].Appearance.AnyRecordFieldCell.HorizontalAlignment = GridHorizontalAlignment.Left;
