The code below shows a LinqToSql table being bound to the control and then accessing the value from the control in the SelectedIndexChanged event.  Hope this helps.

        private void Form1_Load(object sender, EventArgs e)
        {
            NorthwindDataContext db = new NorthwindDataContext();
            this.radMultiColumnComboBox1.DataSource = db.Orders;
            this.radMultiColumnComboBox1.ValueMember = "CustomerID";
        }

        private void radMultiColumnComboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            this.Text = radMultiColumnComboBox1.SelectedValue.ToString();
        }

        CmbTry.DataBindings.Add("SelectedValue", objPatient, "Race")
        'CmbTry.DataBindings.Add("SelectedValue", objPatient, "Race", False, DataSourceUpdateMode.OnPropertyChanged)

        CmbTry.AutoFilter = True
        Dim filter As New FilterExpression(CmbTry.DisplayMember, FilterExpression.BinaryOperation.AND, GridKnownFunction.StartsWith, GridFilterCellElement.ParameterName)
        filter.Parameters.Add(GridFilterCellElement.ParameterName, String.Empty)
        Me.CmbTry.EditorControl.MasterGridViewTemplate.FilterExpressions.Add(filter)

Hello Parag,

Thank you for contacting us.

I reviewed your code, but I am not quite sure that I correctly understand the scenario you are trying to implement. Therefore, I would like to ask you to prepare a sample Windows Forms application that demonstrates what you are trying to achieve. This will allow me to provide you with further help.

Please note you have to open a new support ticket in order to attach a sample project.

Thank you for your time.

Best wishes,
Deyan

Hello Ahmed,

Your code seems to concern a ASP.NET AJAX control, while this forums is for Telerik UI for WinForms. Please address your question in the appropriate forums (http://www.telerik.com/forums/aspnet-ajax) in order to get adequate support.

I hope this helps.
