        End If
    End Sub

    Public Function CreateTable() As DataTable
        Dim myDataTable As DataTable = New DataTable("ParentTable")
        Dim myDataColumn As DataColumn
        Dim myDataRow As DataRow

        myDataColumn = New DataColumn
        myDataColumn.DataType = System.Type.GetType("System.String")
        myDataColumn.ColumnName = "Name"
        myDataTable.Columns.Add(myDataColumn)

        For i As Integer = 0 To 2
            myDataRow = myDataTable.NewRow()
            myDataRow("Name") = "Test " & i
            myDataTable.Rows.Add(myDataRow)
        Next

        Return myDataTable
    End Function

    Private Sub LoadData()
        If ViewState("DataTable") Is Nothing Then
            ViewState("DataTable") = CreateTable()
        End If

        DataGrid1.DataSource = ViewState("DataTable")
        DataGrid1.DataBind()
    End Sub

    Private Sub DataGrid1_EditCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles DataGrid1.EditCommand
        DataGrid1.EditItemIndex = e.Item.ItemIndex
        LoadData()
    End Sub


When i enter in edit mode TimePicker component not function as it was in Readonly mode.
If i put another TimePicker on form outside the CallBackPanel when i enter in edit mode the component in TemplateColumn work.
If i remove the Menu work..
If i remove the CallBackPanel that contain Menu work..
I've try with AjaxUploader into TemplateColumn and the result is the same.

Very Thanks
Samuele

Hi Samuele,

Thanks for having the detailed reproducing code. What you see is mostly normal. Another post explained a similar situation here:

http://www.essentialobjects.com/Forum/Default.aspx?g=posts&t=237

When you use a CallbackPanel to dynamically load a control, since the whole page is not being refreshed, some script modules required by the dynamically loaded control may not be loaded. In this case those script modules should be loaded before the AJAX call --- that is, before you click "Edit" on the Grid. When you put a DatePicker outside of the CallbackPanel, it would do just that. So a workaround is to put a DatePicker outside of the CallbackPanel, but hide it inside a <div style="display:none"></div>. This way the DatePicker is still rendered, but not displayed.

I am not sure why removing the Menu would fix the problem, though. We will look into it and see if we can find out why.

Thanks
Samuele

Hi Samuele,

A cleaner solution is to set this property to "EO.Web.*":
