Binding an UltraCombo with multiple checkboxs into an UltraGridCell
posted

Hi,

I'm trying to bind an UltraCombo to an UltraGrid cell.

My UltraCombo is configured to have multiple selection with checkboxs.

When the UltraCombo is not binded to the grid i can use the multiple selection normally and it works fine, but after i bind it to the grid i can only choose one value (checkbox) and then the UltraCombo closes.

Is there a way to make it stay open and allow me to choose multiple items?

Adding my code (happens on the grid's InitializeLayout event):

UltraCombo ucbx2 = new UltraCombo();
ucbx2.BindingContext = this.BindingContext;
ucbx2.DataSource = mdsLocations.LOCATION;
ucbx2.DisplayMember = "DESCRIPTION";
ucbx2.ValueMember = "LOCATION_KEY";

UltraGridColumn ugc = ucbx2.DisplayLayout.Bands[0].Columns.Add();
ugc.Key = "Selected";
ugc.Header.Caption = string.Empty;
ugc.Header.CheckBoxVisibility = HeaderCheckBoxVisibility.Always;
ugc.DataType = typeof(bool);
ugc.Header.VisiblePosition = 0;


ucbx2.CheckedListSettings.EditorValueSource = EditorWithComboValueSource.CheckedItems;
ucbx2.CheckedListSettings.ListSeparator = " / ";
ucbx2.CheckedListSettings.ItemCheckArea = ItemCheckArea.Item;
ucbx2.DisplayMember = "DESCRIPTION";
ucbx2.ValueMember = "LOCATION_KEY";
ucbx2.CheckedListSettings.CheckStateMember = "Selected";

e.Layout.Bands[0].Columns[LOCATION_KEYColumn.ColumnName].ValueList = ucbx2;
e.Layout.Bands[0].Columns[LOCATION_KEYColumn.ColumnName].Header.Caption = "Location";
e.Layout.Bands[0].Columns[LOCATION_KEYColumn.ColumnName].Style = Infragistics.Win.UltraWinGrid.ColumnStyle.DropDownList;

Thanks,

Ziv.

    Hi,

    I think the problem is probably this:

    ugc.DataType = typeof(bool);

    A bool cell in the grid can only contain one value, true or false. It cannot contain a list of values. Try changing this to:

    ugc.DataType = typeof(object[]);
