Thanks Mike for your help, now it works for me.

Hi Imran,

So you want the set the value without the event firing? You could just use a flag to ignore the event handler. Or even disconnect the event and re-hook it after you set the SelectedIndex.

 Try

            RemoveHandler Me.UltraComboEditor1.ValueChanged, AddressOf Me.UltraComboEditor1_ValueChanged

            Me.UltraComboEditor1.SelectedIndex = ZERO

        Finally

            AddHandler Me.UltraComboEditor1.ValueChanged, AddressOf Me.UltraComboEditor1_ValueChanged

        End Try

Hello Mike,

I want when my form loads, the UltraComboBox should be displaying first value from data source.

Following way I can achieve

Dim dsDataSet As DataSet
        Try
            dsDataSet = getDataSet()

            If dsDataSet .Tables.Count > ZERO AndAlso dsDataSet .Tables(ZERO).Rows.Count > ZERO Then

                ultraComboEditor.DataSource = dsDataSet

                ultraComboEditor.DataMember = dsDataSet .Tables(ZERO).TableName

                ultraComboEditor.DisplayMember = "DISPLAYNAME"

                ultraComboEditor.ValueMember = "ValueCode"

                 ultraComboEditor.SelectedIndex = ZERO
            End If

But catch in this way is that while loading it fires "ultraComboEditor_ValueChanged" Event when code execute following line

ultraComboEditor.SelectedIndex = ZERO

Is there any other way that when ultraComboEditor loads, it should be initialize with value from dsDataSet ?

Thanks,

Imran

Make sure you are setting the Value on the control AFTER you set it's DataSource, DataMember, ValueMember, and DisplayMember.

Also, I think there is an InitialValue property or maybe a SetInitialValue method that might help you here.

When can I set this Value property.  I am linking the combobox to a UltraDataSource that I have populated in the designer so it is unlinked from any kind of database.

In the Form_Load event I try to set the Value to one that is in the list but it is not selected, when the page is displayed.

Where does this line need to be if I want the a specific value selected only when the page is first loaded and not each time the combobox receives an Initialization event?
