User Control in RadWindow causes window to close on postback

Hi
I've got a user control that I've added to a RadWindow, it's an edit page that is opened inside a modal when a row in a grid is clicked instead of redirecting to a new page. To accomplish this in the click event on the row a new User Control is instantiated, data from the row applied to public properties and then the user control is added to the RadWindows list of controls

It loads fine and but when I click anything that causes postback in the edit page inside of the RadWindow the window disappears and no breakpoints in my code behind is hit.

I have confirmed that postback causes the webform to postback and not the user control in the RadWindow.

Is there any way around this?

Updating RadWindow dropdown from a previous RadWindow

Hello,

We have a requirement to allow the user to enter values on a RadWindow (modal type). Based on those values we need to execute business logic on the server and then set a drop down on the next RadWindow. The problem I am facing is that currently we have these set up as one window with separate panels. The first panel is toggled to the next when the first submit is clicked on the window. The second panel should then contain a constrained dropdown of email addresses. I would like this logic to remain on the server as it hits Active Directory and several other business classes in our code. The window is running on client side so even if I call a server side method (onprerender or onpreinit on the window) the next panel is toggled simultaneously and I am unable to set the dropdown contents on the second panel. I thought about just calling another radwindow from code behind. Is there any other way or is this the preferred method to achieve our goals?

Grid - Button click which opens....

Window1 - User answers values that drive drop down on..

Window2 - Contains dropdown that is based on Window1 answers.

-Thanks

My main grid will get populated using one Data Table Customer and Child Grid Will get Populate using different Data table order e.g.

DTCustomer			DTOrder
CustomerID	Name	ContactNumber	CustomerID	OrderNumber	OrderAmount
1	ABC	12345	1	1	100
2	PQR	345	2	2	200
3	XYZ	1456	3	3	300

Please Let me know that how can I bind the grid on NeedDataSource Event so that it will display Customer Data as Parent and Order Data as a Child.
Also please let me know that how can i implement the server side logic to Insert/Update/Delete data to respective tables.

Tree scrolling

Telerik team,

I have radtreeview in radsplitter.[Telerik DLL V2012.1.411.40]
I have a requirement where on a selected index change of RadCombobox a radtree control should be generated. Now if I have selected a value say A from Combobox, the Tree will be generated. Now I select a Node say Node1 from the Tree and then select a different value from Picklist to regenerate the Tree. Now I want that if Node1 is again present as a Node in the new Tree generated, it should be selected and have focus on the respected Node i.e. Node1.

Following is my code

alert(Selectednode.get_text());

}

Error rendering telerik:RadMenu

I have broken down the site I am developing into multiple files developed as user controls. It makes more sense to simply add a single usercontrol than to add half a dozen or more other controls to multiple pages, plus when I need to edit the item it gets applied site-wide. However, there seems to be an issue that I am not sure how to handle.

I have a user control "header.ascx" that is included on several webpages.


<%@ Register Src="menu.ascx" TagName="menu" TagPrefix="uc1" %> 

<div id="header">

<div id="orgname" class="headerinfo" style="position: relative; z-index: 1500; text-align: right">

<asp:Label ID="lblOrganizationName" runat="server" Font-Names="Arial Black" ForeColor="Gray" Text="Organization Name"

Font-Size="Large"></asp:Label>

</div>

<div id="logindetails" class="headerinfo" style="text-align: right; position: relative;

z-index: 1500; top: 0px; left: 0px;">

<asp:Label ID="lblUser" runat="server" Font-Names="Arial" ForeColor="Gray" Text="User Name"

Font-Size="Small"></asp:Label>

<asp:LoginStatus ID="LoginStatus1" runat="server" Font-Names="Tahoma,Arial" ForeColor="#FF6600" />

<asp:Label ID="lblPage" runat="server" Font-Names="Arial Black" ForeColor="Gray"

Text="" Font-Size="Small"></asp:Label>

<uc1:menu ID="menu1" runat="server" />

</div>

As you can see, I have also included a user control "menu.ascx" that is part of the header as well as part of other pages that don't include the full header.

When I view menu.ascx in the IDE, the menu is rendered correctly. If I view header.ascx in the IDE the menu is rendered correctly, however, whenever I view any page in the IDE that has a header user control, I get an error "Unknown server tag 'telerik:RadMenu'" and the menu isn't rendered.

When the menu isn't nested in another user control, it displays correctly. However, when it is included as part of a larger user control, it does not.

I can build the site and it renders correctly in the browser, however, I cannot see how it interacts with the design when it will not show on the main page.

Am I missing a directive or something so this will display?
