Hi,

For years I used the following code:

            Dim dropDown As RadToolBarDropDown = New RadToolBarDropDown("PageSize")
            dropDown.CssClass = "perPageDropDown"
            dropDown.EnableImageSprite = False
            dropDown.Text = GetGlobalResourceObject("Insight", "Per pagina")
            dropDown.ToolTip = GetGlobalResourceObject("Insight", "Per pagina")
            RadFileExplorer1.ToolBar.Items.Add(dropDown)

But after upgrading to R1 2020 i get the error:

Bericht: Value property is not supported by RadToolBarDropDown

Stack Trace:
at Telerik.Web.UI.RadToolBarDropDown.get_Value() at Telerik.Web.UI.RadFileExplorer.ConfigureToolbarButtons() at Telerik.Web.UI.RadFileExplorer.ControlPreRender() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

Any clues?

Hi Marc,

I tested RadFileExplroer with the provided snippet, but the dropdown was properly added at my end. Can you, please, share some more details about the scenario in which the error is thrown?

What was version of the controls you were using prior the upgrade to R1 2020?
In which moment of the page life-cycle are you configuring the Toolbar?
Can you send me a simple page containing the setup needed to replicate the problem?

Below you can see the setup I used for my test:

		<telerik:RadFileExplorer RenderMode="Lightweight" runat="server" ID="FileExplorer1" Width="595px" Height="350px"
			AllowPaging="true" PageSize="10">
			<Configuration EnableAsyncUpload="true" ViewPaths="~/FileExplorer/Examples/Overview/images"
				UploadPaths="~/FileExplorer/Examples/Overview/images" DeletePaths="~/FileExplorer/Examples/Overview/images"></Configuration>
		</telerik:RadFileExplorer>

Protected Sub Page_Load(sender As Object, e As EventArgs)
    Dim dropDown As RadToolBarDropDown = New RadToolBarDropDown("PageSize")
    dropDown.CssClass = "perPageDropDown"
    dropDown.EnableImageSprite = False
    'dropDown.Text = GetGlobalResourceObject("Insight", "Per pagina")
    'dropDown.ToolTip = GetGlobalResourceObject("Insight", "Per pagina")
    FileExplorer1.ToolBar.Items.Add(dropDown)
End Sub

Hello Marc,

Thank you for the details, we managed to track down the issue and indeed this is a regression as of R1 2020.

I have logged the new issue in our feedback portal and we will do our best to fix it for the upcoming R2 2020 Service Pack in mid-June.
