Dynamic datagrid column with an inherited ITemplate column

[tyris]

hi,

i'm making a code that generates TemplateColumns into a datagrid depending on a dataset, each column name is dynamic and not hard coded thanks to this.

I read many documentation on the net (mainly here :

http://www.tripleasp.net/article.aspx?NavID=27

)

It's almost done (table is filled correctly, columns are generated) except one thing : clicking on Edit command does not display a textbox.
I created a "Edit" column and assigned the command "Edit" to the label (as i always do). So the problems is here is guess:

Dim tc1 As TemplateColumn = New TemplateColumn()
tc1.ItemTemplate = New CTemplateColumn("test")
tc1.EditItemTemplate = New ValidateEditItem("test") 'HERE
tc1.HeaderText="my header"
DataGrid1.Columns.Add(tc1)

I wonder where my error is...

=============================================
here is the code sample :

Public Class ValidateEditItem
    Implements ITemplate

    Private colname As String

    Public Sub New(ByVal cname As String)
        colname = cname
    End Sub

    Public Sub InstantiateIn(ByVal container As Control) Implements ITemplate.InstantiateIn

        Dim tb As TextBox = New TextBox()
        AddHandler tb.DataBinding, AddressOf BindData
        container.Controls.Add(tb)
        tb.ID = colname
        Dim rfv As RequiredFieldValidator = New RequiredFieldValidator()
        rfv.Text = "Please Answer"
        rfv.ControlToValidate = tb.ID
        rfv.Display = ValidatorDisplay.Dynamic
        rfv.ID = "validate" + tb.ID
        container.Controls.Add(rfv)
    End Sub

    Public Sub BindData(ByVal sender As Object, ByVal e As EventArgs)
        Dim tb As TextBox = CType(sender, TextBox)
        Dim container As DataGridItem = CType(tb.NamingContainer, DataGridItem)
        Dim drv As DataRowView = CType(container.DataItem, DataRowView)
        tb.Text = CType(drv(colname), String)
    End Sub
End Class

=========================================


Do you have any clue to help me ?
