And mij code-behind page:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
            Dim _controller As New BDB_Promo_SettingsController

            colBDB_Promo_Settings = _controller.GetAllBDB_Promo_Settings()
            gridPromo.DataSource = colBDB_Promo_Settings
            gridPromo.DataBind()

            windowPromo.VisibleOnPageLoad = True
            windowPromo.Visible = False
        End Sub
        Protected Sub imgBuAdd_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles imgBuAdd.Click
            windowPromo.Visible = True
        End Sub
        Protected Sub imgbuRefresh_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles imgbuRefresh.Click

        End Sub
        Protected Sub gridPromo_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles gridPromo.ItemCommand
            lblTest.Text = "dddddddffff"
            lblTest.Visible = True
        End Sub
        Protected Sub gridPromo_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles gridPromo.PreRender
            Dim gridRows As GridItemCollection = gridPromo.Items
            Dim obj As BDB.Modules.BDB_Promo_Settings.BDB_Promo_SettingsInfo
            Dim afbeelding As System.Web.UI.WebControls.Image

            For Each data As GridDataItem In gridRows
                obj = data.DataItem
                afbeelding = CType(data.FindControl("afbPromo"), System.Web.UI.WebControls.Image)
                afbeelding.ImageUrl = obj.Lokatie
                afbeelding.ToolTip = obj.Alt
                afbeelding.Height = 100
                afbeelding.Width = 100
            Next
        End Sub
#End Region

Hello Jennifer,

The DeleteCommand will not fire as the grid is rebound on every postback. So try replacing the code in the PageLoad event with the following code:
VB:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
          If Not IsPostBack
            Dim _controller As New BDB_Promo_SettingsController

            colBDB_Promo_Settings = _controller.GetAllBDB_Promo_Settings()
            gridPromo.DataSource = colBDB_Promo_Settings
            gridPromo.DataBind()

            windowPromo.VisibleOnPageLoad = True
            windowPromo.Visible = False
          End If
End Sub

Thanks
Princy.
