Setting RadWindow's position from client side

Hi,
I have a header, a footer and a body area. In body area I have a splitter which contains a left pane, a resizable splitbar, and a right pane. The right pane is content area where the data is presenting and the left pane is for navigation. when an user want to edit an object, the object is opened in a radwindow. The problem is that I want to set the position and size of the rad window to fill the content area so that the user doesn't know that the object is opened in a radwindow.

I'm able to set the height and width of the radwindow so it fits the content area from the client side, but i couldn't set the position of the radwindow at the same position.

One last question, how can I remove the titlebar och the statusbar of the radwindow making it transparent so it fits it the scen above?

Context Menu on Navigation

Hi there,

We are trying to attach a Context Menu to RadNavigation, see sample code below. The context menu only opens for the top level items in the the RADNavigation and not the sub-items. How can we get it working with the sub-items too?

<telerik:RadNavigation ID="RadNavigation1" runat="server" Skin="Bootstrap" MenuButtonPosition="Left" OnClientContextMenu="OnClientContextMenu"
    EnableViewState="false" OnNodeDataBound="RadNavigation1_NodeDataBound" OnClientNodeMouseEnter="OnClientNodeMouseEnter"
    OnClientNodeMouseLeave="OnClientNodeMouseLeave" DataSourceID="SiteMapDataSource1" OnDataBound="RadNavigation1_DataBound">
    <Nodes>
    </Nodes>
</telerik:RadNavigation>
<telerik:RadContextMenu runat="server" ID="ContextMenu2" Skin="Bootstrap" EnableViewState="false"
    OnClientItemClicked="OnClientItemClickedContextMenu">
    <Targets>
       <telerik:ContextMenuControlTarget ControlID="RadNavigation1" />
    </Targets>
    <Items>
        <telerik:RadMenuItem Text="Move item up" Value="MoveUp" />
        <telerik:RadMenuItem Text="Move item down" Value="MoveDown" />
    </Items>
</telerik:RadContextMenu>

The HTTP verb POST used to access path '/virtual/' is not allowed.

I am using a RadGrid and capturing the client click of a row through OnItemCommand. I receive the error:

The HTTP verb POST used to access path '/virtual/' is not allowed.

Code (simplified):

protected void Grid_OnItemCommand(object sender, GridCommandEventArgs e)

{

...

Response.Redirect("~/Page.aspx?id=" + id, false);

...

}

I think the issue is that the landing page is at the root of the virtual directory. So the postback from the grid is going to /virtual/ and not /virtual/Default.aspx. I think IIS doesn't like the lack of a page.

How do I stop these errors when posting back in a grid to a default document? I can't tell users to type in a fully qualified URL.

Filtering to use both DataTextField and DataValueField

I'm using the RadComboBox to display a list of reports to a user. The reports have and ID and Name which are bound as such DataTextField="Text" DataValueField="ID".

The ID of the report is not useful to the end user so we don't want to display the Report ID in the text. However, our site admins and client services people who know the Reports best by ID wish to be able to type the Report ID to filter it this way.

Is it possible to provide such custom filtering?

Server side caching blocking new skin updates

Hi there,

I am trying to set up a new skin for Telerik UI for ASP AJAX. I’ve been able to set up the skin without too much issue, but a lot of the CSS changes I am making – especially to do with images – seem to be overridden by a file called WebResource.axd. This appears to be a server side caching file. However, I am unable to find out how to clear or refresh this cache.

Can anybody please help and point me in the direction of some way of solving this?

Thanks very much!
