Telerik support site is not working !!!!

Hai,

I am using Windows 7. Your support website is showing only black screens. Demos, Documentation and Knowledge Base are not working. It shows a javascript with blank screen. I tried it in IE 8, Mozilla, Google Chrome, Opera. Its not working in any of these browsers. There is no firewall or any such security issues as no other websites have this issue. There is no javascript issues as javascripts in all other websites are working correctly. Also it is my development computer, I am sure that, there is no issue with javascripts in browsers as my own javascripts works properly. It is the problem with telerik website itself. Please solve it at the earliest.

ContextMenu does not load

I am using the RadTreeView in a asp.net form. I am trying to implement the ContextMenu on each node. The problem that I am having is that the ContextMenu does not display on right click

In my .ascx I define my RadTreeView and menu like this:
<telerik:RadTreeView ID="RadTreeView1" runat="server" EnableDragAndDrop="True" OnNodeDrop="RadTreeView1_NodeDrop"

    OnNodeClick="RadTreeView1_NodeClick" OnContextMenuItemClick="RadTreeView1_ContextMenuItemClick" AllowNodeEditing="true"
    OnNodeDataBound="RadTreeView1_NodeDataBound">
        <ContextMenus>
        <telerik:RadTreeViewContextMenu runat="server" ID="AssetMenu" ClickToOpen="True" Skin="Vista">
            <Items>
                <telerik:RadMenuItem Text="Select Asset" Value="Select">
                </telerik:RadMenuItem>
                <telerik:RadMenuItem Text="View Hierarchy" Value="View">
                </telerik:RadMenuItem>
            </Items>
        </telerik:RadTreeViewContextMenu>
    </ContextMenus>
</telerik:RadTreeView>

In my code behind, after I dynamically populate the RadtreeView, I try to attach the ContextMenu as follows. This is the last thing done in my Code behind:

            foreach (RadTreeNode node in RadTreeView1.GetAllNodes())
            {
                node.ContextMenuID = "AssetMenu";
                node.EnableContextMenu = true;
            }

Everything works except that the ContextMenu does not display when I right click an item.

Which native CSS file to include if EnableEmbeddedSkins and EnableEmbeddedBaseStylesheet are false in web.config

Hi,

in appSettings my web.config has
<add key="Telerik.EnableEmbeddedSkins" value="false" />
<add key="Telerik.EnableEmbeddedBaseStylesheet" value="false" />

which files should I include in page to make ImageEditor appear fully styled?
I have in head:

<telerik:RadStyleSheetManager ID="RadStyleSheetManager2" runat="server">

<StyleSheets>

<telerik:StyleSheetReference Name="Telerik.Web.UI.Skins.ImageEditor.css" Assembly="Telerik.Web.UI" />

<telerik:StyleSheetReference Name="Telerik.Web.UI.Skins.Default.ImageEditor.Default.css" Assembly="Telerik.Web.UI" />

<telerik:StyleSheetReference Name="Telerik.Web.UI.Skins.ToolBar.css" Assembly="Telerik.Web.UI" />

<telerik:StyleSheetReference Name="Telerik.Web.UI.Skins.Default.ToolBar.Default.css" Assembly="Telerik.Web.UI" />

<telerik:StyleSheetReference Name="Telerik.Web.UI.Skins.Dock.css" Assembly="Telerik.Web.UI" />

<telerik:StyleSheetReference Name="Telerik.Web.UI.Skins.Default.Dock.Default.css" Assembly="Telerik.Web.UI" />

</StyleSheets>

</telerik:RadStyleSheetManager>

I don't see tool bar button images, no dialog button images, also some dialogs look a bit "unfinished".

Thank you!

Binding, ExtractValues GridTemplateColumn

Currently when I call ExtractValues it does not return the values for GridTemplateColumns.
The OnInsertCommand Event handler below shows the code I use to get values from a row in the grid.

Public Sub InsertTimesheetItemCommand(ByVal source As Object, ByVal e As GridCommandEventArgs)

Dim editableItem As GridEditableItem = DirectCast(e.Item, GridEditableItem)

Dim values As New Hashtable()

editableItem.ExtractValues(values)

End Sub

Below is one of the GridTemplateColumns that does not have its value returned.

<telerik:GridTemplateColumn HeaderText="Job" UniqueName="JobColumn" DataField="JOB_ID" ItemStyle-Width="50px" >

<ItemTemplate>

<asp:Label ID="Label1" runat="server" Text='<%# Eval("Job_Description") %>' />

</ItemTemplate>

<EditItemTemplate>

<telerik:RadComboBox runat="server" ID="JobList" DataTextField="Description" DataValueField="Value" Text="Job" >

</telerik:RadComboBox>

</EditItemTemplate>

</telerik:GridTemplateColumn>

Note for this example I want to get the selected value from the combo box displayed in the Hashtable from the extract values method with a key of JOB_ID.

Any help would be much appreciated

rad upload control

Hi folks,

Im new to telerik controls and i was wondering the following:

is the latest version of the telerik rad upload control supporting multiple file upload ?
That is in 1 DIALOGUE. So NOT 10 single upload controls... and call it multiple upload control....
I find that there is no way you should call it mutliple file upload if you set 10 single file uploaders after eachother.
Thats just cheating :p

Im not flaming here, i love the controls.

Then, is there a possibility to change the control in source code, so that you can define a file limit depending on the extension ?
Or is this almost not able to archieve ? So fe. I want the user to restrict jpeg files up to 2MB... and then wmv files up to 10MB.

Thx alot in advance, any info you can give me , is much appreciated :)

*edit* so sorry about the crappy title :(, cant adjust it

But now (with all the properties same) I am getting the pager at the bottom of the data div after I scroll till the bottom. 

Attached are the images [hope the hidden data is not a problem]. Can you please help me getting the pager properly. The aspx code for the grid is :
