ComboEditor with checkbox with a grid

Hello Support,

We are working on comboeditor with checkboxes, we are displaying the comboeditor with a xamdatagrid. We are able to bind the comboeditor but we do not know how to dispaly the checkboxes with the combo editor.

In the design mode we have written following code :

<igEditors:ComboBoxItemsProvider x:Key="ComboItemsProvider">

<igEditors:ComboBoxItemsProvider.Items>

<CheckBox Content="Abcd"/>

<CheckBox Content="Efgh"/>

<CheckBox Content="Ijklm"/>

</igEditors:ComboBoxItemsProvider.Items>

</igEditors:ComboBoxItemsProvider>

For binding the source to the comboeditor we have written following code :

ds = objProductionNode.GetProductionNodeInfo()

Dim comboProvider As ComboBoxItemsProvider = TryCast(Me.xamGridSubDepartment.TryFindResource("ComboItemsProvider"), ComboBoxItemsProvider)

comboProvider.ItemsSource = ds.Tables(0).DefaultView

comboProvider.DisplayMemberPath = ds.Tables(0).Columns("ProductionNodeName").ToString()

comboProvider.ValuePath = ds.Tables(0).Columns("ProductionNodeID").ToString()

We tried attaching the items at the design time with the check box, but when we try to bind the dataosource to the combo, it gives an exception saying "items must be empty before assinging item source". We tried removing the items which we binded at the design time. After removing these items from the design time the items do appear in the combo editor but without the checkbox.

Can you please tell us where we are going wrong. Please let us know if there is any way to add the check box to the comboeditor (in the xamdatagrid) and bind the combeditor with the datasource.

Please find attached the screen shot for your reference.

Hello,

The links that you provided show examples of a xamComboEditor by itself and a xamDataGrid inside a xamComboEditor.

We were able to achieve the above by using the following code in the click event of the checkbox inside the xamComboEditor.

cbobxDates.Text = ""

tempDateItems = ""

For Each f As ComboCheckboxValues In dateItems

If (f.IsChecked) Then

cbobxDates.Text += f.Name + ","

tempDateItems += f.Value + ","

End If

Next

cbobxDates.ItemsSource = Nothing

cbobxDates.ItemsSource = dateItems

'cbobxDates is the xamComboEditor

'dateItems contains items of the xamComboEditor

However now we require a xamComboEditor placed in column of a xamDataGrid that allows multiple selection, and hence are facing a problem. We basically need to access the Text property of the xamComboEditor at run time.

Thank You.

Hello,

I have been looking into your latest request and I can suggest you use the Utilities class to get an instance of the specified cell’s XamComboEditor or you can try the EditModeStarted/Starting and use the event args’s Editor property. Please let me know if this helps you or I have misunderstood you in any way.

Looking forward for your reply.
