'<%# Bind("MyProperty")>' in code-server

[Nguyen]

Hi telerik team.

My purpose is create a column that have a combo as a editor, and when user choose the item in combo box, it send both ID and Code back to the server to bind to datacontext of the row.

To do dat, I have a Template column in Markup code: 

<telerik:GridTemplateColumn>
<ItemTemplate>
<asp:Label Text='<%# Bind('Code')%> runat="server" ID=Label1></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<telerik:RadComboBox runat="server"
ID="col_Editor"
SelectedValue='<%# Bind("ID")%>'
Text='<%# Bind("Code")%>'
DataTextField="Code"
DataValueField="ID"></telerik:RadComboBox>
</EditItemTemplate>
</telerik:GridTemplateColumn>

 It work fine. But now, i want to wrap this into 1 class call "MyComboboxColumn" and the problem is i can not find the way to make a '<%# Bind("")>' tag in the behind code.

My class look like:

Public Class MyComboboxColumn
    Inherits GridTemplateColumn

    Public Property DataTextField As String

    Public Property DataValueField As String

    Public Overrides Sub PrepareCell(cell As TableCell, item As GridItem)
        If TypeOf item Is GridDataItem AndAlso TypeOf item Is MyEntity Then
            Dim ent = CType(item.DataItem, MyEntity)

            Dim displayText = ent.GetValueByPropertyName(DataTextField)
            If Not item.IsInEditMode Then
                cell.Text = displayText
            Else
                Dim combo As RadComboBox = cell.FindControl(Me.UniqueName & "_Editor")
                combo.Text = displayText
                combo.SelectedValue = ent.GetValueByPropertName(DataValueField)
            End If

            MyBase.PrepareCell(cell, item)
        End If
    End Sub

    Protected Overrides Function CreateDefaultColumnEditor() As IGridColumnEditor
        Return New MyComboboxColumn_Editor(Me)
    End Function
End Class

Public Class MyComboboxColumn_Editor
    Inherits GridTemplateColumnEditor

    Public Property Owner As MyComboboxColumn

    Public Sub New(_owner As MyComboboxColumn)
        Owner = _owner
    End Sub

    Protected Overrides Sub AddControlsToContainer()
        Dim combo As New RadComboBox
        With combo
            .ID = Owner.UniqueName & "_Editor"
            .DataSource = MyDataSource()
            .DataValueField = Owner.DataValueField
            .DataTextField = Owner.DataTextField
            .DataBind()
        End With

        HtmlContainerControl.Controls.Add(combo)
    End Sub
End Class

I can send the value and text to the editor. But i do not know how to send back from editor to the container.
