Problems With MultiColumn Combobox

[Daniel]

Hi all,

I have 2 problems with Multi Column Combobox:

1. There is an event like "SelectionChangeCommitted" (in the normal combobox)? Because I need to fire an event to catch the value selected when the user selects the row on multi column combobox. I can't use SelectedIndexChanged event because my combo have a datasource.

2. Everytime i click for the first time on combo to open, that don't display correctly as I coded (ex. .AutoSizeDropDownToBestFit = True). It just displays correctly after the first click.

Sorry for my bad English.
I'm using Q3 RadControls.
I'm programming in VB.NET 2010.

Thanks for supporting me :)

Hi Safds,

Thank you for writing.

The RadMultiColumnComboBox is not designed to support "SelectionChangeCommitted" event because everything that user can achieve with this event can be achieved with the SelectedIndexChanged event too.

You can use SelectedIndexChanged with every type of data source. For example :

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
    'TODO: This line of code loads data into the 'NwindDataSet.Employees' table. You can move, or remove it, as needed.
    Me.EmployeesTableAdapter.Fill(Me.NwindDataSet.Employees)
    Me.RadMultiColumnComboBox1.AutoSizeDropDownToBestFit = True

End Sub

Private Sub RadMultiColumnComboBox1_SelectedIndexChanged(sender As System.Object, e As System.EventArgs) Handles RadMultiColumnComboBox1.SelectedIndexChanged
    Me.RadLabel1.Text = String.Format("Row changed :{0}", RadMultiColumnComboBox1.EditorControl.Rows(RadMultiColumnComboBox1.SelectedIndex).Cells(2).Value)
End Sub

In regards to the second question, I tried to reproduce the described issue locally with version Q3 2012 (2012.3.1017) but everything is working correctly on my end. There is sample demo project attached which I have used in my tests. Could you please take a look at it and modify it on a way to replicate the undesired behavior. This will allow me to investigate it and provide you with further support.

Thank you in advance for your collaboration. I am looking forward to your reply.
