The value property nor display property is not bound.  The datasource is bound to a dataset and the datamember is bound to datatable within the dataset.  The datatable has four columns and I'm adding the unbound "Selected" column at runtime.

After your comment about the bound field that is unable to handle the value made me check one other thing.  If I select just one check box in the list it will let me move focus.  If I select more than one it will not. 

There is no logic for validation within my code.

It sounds like something is preventing the focus from leaving the control. This is usually caused by validation, as in the Validating event.

Are you binding the Value property of the UltraCombo? If so, it's probably bound to a field that is unable to handle the value you are giving it, which in this case would be an array of objects.

If that's not the case, then you might want to check the Validating event and see if the e.Cancel parameter is being set to true for some reason. Check the e.Cancel even if you are not already handling the event - it might be coming into the event already set to false if someone else is cancelling it.

If none of that helps, see if you can duplicate this behavior in a small sample project and attach it here (you can attach files on the options tab), and we will be happy to take a look.

Mike,

I've created a form with Splitter Panel.  Bottom half of panel has Ultra Grid and upper half has Ultra Combo.   All work well until I add the following line of code:

Me.cboJobCodeList.CheckedListSettings.EditorValueSource = Infragistics.Win.EditorWithComboValueSource.CheckedItems

When this line is added, and you close the dropdown you see the selections: 1120, 1145, 1160
But you cannot move focus to another control.  You cannot even click the X to close the application.  If I comment out the line after selecting multi lines and closing up the dropdown I can move focus to other objects, but you only see the last item selected:  1160

 I've bound it to a datasource and used the following code.

cboJobCodeList.InitializeLayout

)

checkColumn.DataType =

)

checkColumn.Header.VisiblePosition = 0

.Always

checkColumn.Header.Caption =

.Empty

.cboJobCodeList.CheckedListSettings.CheckStateMember = checkColumn.Key

.CheckedItems

.Item

","

"prjb_code"

"prjb_code"

Sub

The following code maybe of help and assumes that the Wincombo control is bound to a data table.

using

Infragistics.Win;

Infragistics.Win.UltraWinGrid;

...

this.ultraCombo1.DisplayMember = "FirstName";

this.ultraCombo1.ValueMember = "EmployeeID";

// The column assigned to the CheckStateMember property works best for Boolean columns

this.ultraCombo1.CheckedListSettings.CheckStateMember = "IsActive";

// Set up the UltraCombo to show the checkbox middle-center aligned

ContentAlignment.MiddleCenter;

column.Editor = checkEditor;

Hi Brain,

I am also looking for the same behaviour that want to add Check box in Ultra Combo Box but i am having a different scenario here I am filling the datasource of the Ultra Combo Box using a DataTable.

In my form in the Combo Box i am filling it with only one column using Data Source now i want check box with those items which i got from data source.

the way which u show how will it work in this case???can u plz give some more idea here...
