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

Upload (Obsolete)

Hi,



I recently upgraded my rad grid from classic to Asp.Net AJAX Q1 grid.

Earlier (before upgrading) I could see the pagination properly. 

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 :
