[Solved] Re-expanding a node doubles (multipies) children

Hi support team,

Telerik TreeView is awesome, all my requirements are met. Great job!
But here I am stuck:

- I have a tree and the user can select multiple nodes.
- Initially, some nodes are expanded, so that all selected nodes are displayed. I do this with a datasource and with the OnNodeDataBound.
- All nodes can be expanded with TreeNodeExpandMode.WebService

All works fine but when I collapse a initially loaded node, and then expand it again, the number of child nodes doubles, each child node is contained twice. When I do this again, it is still contained twice (not tree times).

How does the control do the "identity". Is is not the RadTreeNode.Value?
One workaround is the set the ExpandMode of RadTreeNode to Server to all nodes that are initially expanded. But then the user can not collapse it (nothing happens when the user clicks -). Best regards, a good customer

[Solved] OnClientClicking & RequiredFieldValidator problems

I have looked at the following forum post: http://www.telerik.com/forums/strange-behavior-when-using-args-set-cancel-true and although my code is similar still having odd behavior.

When clicking on the radButton it will fire the validation but it takes clicking on the "OK" button twice before the validation summary disappears.

Suggestions?

<telerik:RadCodeBlock runat="server">

<script type="text/javascript">

function ShowConfirm(clickedButton, args) {

var validated = Page_ClientValidate('Form');

if (validated) {

args.set_cancel(true);

function callBackFunction(arg) {

if (arg == true) {

clickedButton.click();

}

//Open the window

$find("<%=confirmWindow.ClientID %>").show();

//Focus the Yes button

$find("<%=btnYes.ClientID %>").focus();

//Cancel the postback

args.set_cancel(true);

}

function YesOrNoClicked(sender, args) {

var oWnd = $find("<%=confirmWindow.ClientID %>");

oWnd.close();

if (sender.get_text() == "Yes") {

$find("<%=_btnFinish.ClientID %>").click();

}

</script>

</telerik:RadCodeBlock>

<asp:Panel runat="server" ID="ShowHistorical" Visible="false">

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.

[Solved] 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>
