This seems somewhat mad.

I've worked out a work around to get the ID that should have been selected to be selected. Luckily the SelectedText property does amazingly seem to work .

    
                                uxEditStatus.SuspendLayout()  
        
                                For Each item As Telerik.WinControls.UI.RadComboBoxItem In uxEditStatus.Items  
        
                                    If item.Value.ToString() = IDTOMATCH Then uxEditStatus.SelectedText = item.Text  
        
                                Next 
        
                                uxEditStatus.ResumeLayout()

I'd love to know if the SelectedValue property is a somewhat odd 'feature' or if it is a bug...

Regards,

Jon

Or use the FindIndex sub below and pass it the combobox and ID to find. Perhaps this functionality could be introduced into the combobox in a future release if the SelectedValue is by design?

    
            Public Sub FindIndex(ByRef combobox As Telerik.WinControls.UI.RadComboBox, ByVal indexValue As String)  
        
                combobox.SuspendLayout()  
        
                Dim i As Integer = 0  
        
                For Each item As Telerik.WinControls.UI.RadComboBoxItem In combobox.Items  
        
                    If item.Value.ToString() = indexValue Then combobox.SelectedIndex = i  
        
                    i += 1  
        
                Next 
        
                combobox.ResumeLayout()  
        
            End Sub

Hello Jon,

Thank you for contacting us. I cannot reproduce the bug you reported using the following test code:

    
            private void Form2_Load(object sender, EventArgs e) 
        
            { 
        
                        DataTable t = new DataTable(); 
        
                        t.Columns.Add("A", typeof(string)); 
        
                        t.Columns.Add("B", typeof(int)); 
        
                        t.Rows.Add("text 1", 0); 
        
                        t.Rows.Add("text 2", 1); 
        
                        this.radComboBox1.DataSource = t; 
        
                        this.radComboBox1.DisplayMember = "A"; 
        
                        this.radComboBox1.ValueMember = "B"; 
        
            } 
        
            private void radButton1_Click(object sender, EventArgs e) 
        
            { 
        
                        this.radComboBox1.SelectedValue = 1; 
        
            }

However, we are very eager to help you further. Please double check your code, and if everything seems ok, send us a sample application or code snippet that reproduces the issue. In this regard, do you use the latest release - Q1 2009 SP1?

All the best,
