Delete Key

We have the Filemanager on a screen and depending on the role the user is they will not be able to delete files. I remove Delete from the toolbar and I also removed from the ContextMenu, but for some reason if the user clicks on file and hits the delete key they can still delete the file.

I tried to add
if (e.Command == "DeleteFile")
e.Cancel = false;

to the OnItemCommand. When I hit the delete key it will run through this logic but it still deletes the file.

couldn't find the temp file (got removed just before saving)

Hi expert,

I have this exception when excuting this code:

If AsyncUpload1.UploadedFiles.Count > 0 Then

AsyncUpload1.UploadedFiles(0).SaveAs(Server.MapPath(

"/documents") & fileName, True)

End If

then exception occurs:

Could not find file 'xxx\App_Data\RadUploadTemp\mq1ukeso.2dm'.

During debugging, I noticed that temp file 'mq1ukeso.2dm' is existed just before excuting 'SaveAs' method, and it disappear when excuting 'SaveAs...' method, is there any obvious mistake I made? many thanks for your help!

my aspx page:

<telerik:RadAsyncUpload ID="AsyncUpload1" runat="server"

OnClientFileUploaded="OnClientFileUploaded"

MaxFileSize="2097152" MaxFileInputsCount="1"

AutoAddFileInputs="false" />

RadMenu ItemClick Not Firing with ItemTemplate

I am trying to get a horizontal list of RadButtons. So far, the best way I've been able to accomplish this is by using a RadMenu, and adding an ItemTemplate containing a RadButton.
However, this causes the menu's ItemClick to not fire.

Is there a way to use the itemtemplate to force the menu options to look like radbuttons, and still have the ItemClick event fire? Or is there a better way to get a horizontal list of buttons? (I had just a bunch of buttons, but I want to share the click event and just look for the clicked one, rather than having separate button click events).

Thanks for any help!
Here's my markup:

<telerik:RadMenu ID="radMenuRegions" runat="server" Width="100%" BackColor="White" Skin="" OnItemClick="radMenuRegions_ItemClick" >

<ItemTemplate>

<telerik:RadButton ID="radBtn" runat="server"

Text='<%# DataBinder.Eval(Container, "Text")%>' Skin="WebBlue" Width="100px" Font-Names="Arial" Font-Size="14pt" Height="65px" style="margin:20px;" OnClick="radBtn_Click"></

telerik:RadButton>

<telerik:RadToolTip ID="toolTip" runat="server" TargetControlID="radBtn" Title='<%# DataBinder.Eval(Container, "Text")%>' Skin="WebBlue" Text='<%# DataBinder.Eval(Container, "Value")%>'></telerik:RadToolTip>

</ItemTemplate>

<Items>

<telerik:RadMenuItem Text="East" Value="1" />

<telerik:RadMenuItem Text="Main/FHC" Value="2" />

<telerik:RadMenuItem Text="Medina" Value="3" />

<telerik:RadMenuItem Text="West" Value="4" />

<telerik:RadMenuItem Text="Wooster" Value="5" />

</Items>

</telerik:RadMenu>

Resize window when RadPanelbar Expand/Collapse

Hi,

I have a radwindow with a PanelBar inside.

I declare the window like this:

<telerik:RadWindow

ID="RadWindow1"

runat="server"

AutoSizeBehaviors="Width, Height"

AutoSize="true"

VisibleStatusbar="false"

Behaviors="Move"

VisibleOnPageLoad="false"

ReloadOnShow="true"

Modal="true"

NavigateUrl="Popup_Add.aspx"

OnClientClose="OnClientclose"

EnableShadow="true">

</telerik:RadWindow>

And inside the Popup_Add.aspx I have the RadPanelBar inside a tableCell, inside an updatepanel

<asp:TableCell

ColumnSpan="3"

VerticalAlign="Middle">

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">

<ContentTemplate>

<telerik:RadAjaxPanel

ID="RadAjaxPanel1"

runat="server">

<telerik:RadPanelBar

runat="server"

ID="RadPanelBar1"

ExpandMode="MultipleExpandedItems"

Width="100%">

<Items>

<telerik:RadPanelItem Expanded="false" Text="Advanced Settings" runat="server">

<Items>

<telerik:RadPanelItem Value="AccountInformation" runat="server">

<ItemTemplate>

[controls here]

</ItemTemplate>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelBar>

</telerik:RadAjaxPanel>

</ContentTemplate>

</asp:UpdatePanel>

</asp:TableCell>

</asp:TableRow>

</asp:Table>

based on http://demos.telerik.com/aspnet-ajax/window/examples/autosize/defaultcs.aspx
I think I am supposed to call 'popup.autoSize(true);'

But I am not sure how to wire it.

I already have this in the window to close it, so I could reuse the GetRadWindow() for the autosize.
I just need to know how to call it for the RadPanelBar expand/collapse

<script type="text/javascript">

function GetRadWindow() {

var oWindow = null;

if (window.radWindow) oWindow = window.radWindow;

else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;

return oWindow;

}

function CloseWithArg(arg) {

GetRadWindow().close(arg);

}

</script>
