Hi Guys,

The following errors show up when I tried to add data to ultra combo editor:

Error Description: Unable to cast object of type 'Infragistics.Win.ValueListItemsCollection.get_Item(Int32 Index)

at Infragistics.Win.ValueListItemMetrics.IntializeValueListItemsSizeCache(Boolean rebuild)

at Infragistics.Win.ValueList.set_CheckBoxStyle(CheckStyle value)

at

Infragistics.Win.UltraWinEditors.UltraComboEditor.APplyCheckedListSettings(ValueList valuelist)

at Infragistics.Win.UltraWinEditors.UltraComboEditor.get_Items()

Here is my code: 

objMultiSelect.Items.Clear();       

// Add Items to the multi-select list

            objMultiSelect.Items.Add(

"test1");

            objMultiSelect.Items.Add(

"test2");

            objMultiSelect.Items.Add(

"test3");

// Config objmultiselect list here       

this.objMultiSelect.CheckedListSettings.CheckBoxStyle = Infragistics.Win.CheckStyle.CheckBox;           

this.objMultiSelect.CheckedListSettings.CheckBoxAlignment = ContentAlignment.MiddleLeft;         

this.objMultiSelect.CheckedListSettings.EditorValueSource = EditorWithComboValueSource.CheckedItems;

this.objMultiSelect.CheckedListSettings.ItemCheckArea = ItemCheckArea.Item;      

//Add the value changed event handler          

this.objMultiSelect.ValueChanged += new EventHandler(this.OnValueChanged);

ICheckedItemList list = this.objMultiSelect.Items.ValueList as ICheckedItemList;

list.SetCheckState(0,CheckState.Checked);

Any ideas?

Thanks
