Client-Side checkboxes within a RadTreeview not decorated

Hello,

we've experienced a problem with the formdecorator control when using client-side-scripting.
If we add new nodes to a radtreeview on the client-side these checkboxes were not decorated.

For better understanding we have attached an example.
Could you please help us solving this issue.

function addNode(parentNode,nodeText,nodeValue,nodeCheckable,nodeChecked)
                {
                    var treeView= $find("navTree");

                    treeView.trackChanges();

                    //Instantiate a new client node
                    var node = new Telerik.Web.UI.RadTreeNode();
                    //Set its text

                    node.set_text(nodeText);
                    node.set_value(nodeValue);
                    if (!nodeCheckable) { node.set_checkable(nodeCheckable); }
                    if (nodeCheckable && nodeChecked) { node.check() }
                    node.set_postBack(false);

                     //Add the new node as the child of the selected node or the treeview if no node is selected
                    if (!parentNode) {
                        parentNode = treeView.get_selectedNode() || treeView;
                    }
                    parentNode.get_nodes().add(node);

                    //Expand the parent if it is not the treeview
                    if (parentNode != treeView && !parentNode.get_expanded()) {
                        parentNode.set_expanded(true);
                    }
                    treeView.commitChanges();
                    return false;
                }

Get RadGrid Eval Value from Hiddenfield with Javascript to C# Codebehind

I am trying to get an Eval value from my radgrid to my c# codebehind. The value is binded to a hiddenfield and I want to get the value after I hit the built in edit button. To achieve this I am trying to get the hiddenvalue1 to javascript and then somehow get it to my c# code behind. The closest thing I have come to that is binding the value to a hyperlink that when clicked shows an alert with the binded value as shown below. I need something that is automatic where I don’t need to hit a button. Can anyone help?

<asp:HyperLink id="hklk" runat="server" Text='<%# Eval("id") %>' onclick="return GiveAlert(this);"></asp:HyperLink>

function GiveAlert(con)

{

alert(con.innerHTML);

return false;

}

Implementing two way binding for non databound controls

Hi

i am currently trying to bind a object property to a RadTextBox and am getting the following error when using the <%# Bind(DataItem.Name) %> method:

    
            System.InvalidOperationException: Databinding methods such as Eval(), XPath(),  
        
            and Bind() can only be used in the context of a databound control.

I can bind using the following, but it is only one way:

    
            %# DataBinder.Eval(this, "DataItem.Name") %>

How can i get two way binding?

RadGrid DropDownFilter with Default FilterOptions

I have not found an example of a radgrid filter that uses a dropdown list to display the filter list of options but does not use selectedindexchanged to fire the event. I would like it to use the standard filteroptions and filter icon when firing a sort event. Is this possible?

RadGrid Usercontrol Caption lost on postback

In a grid that I'm using I have the following declaration:

<EditFormSettings CaptionFormatString="Edit detail : {0}"
CaptionDataField="ID" PopUpSettings-Modal="true" EditFormType="WebUserControl"

UserControlName="editDetail.ascx">

</EditFormSettings>
And it works fine as long there are no postbacks within the edit form.
On that usercontrol is a dropdownlist that has OnSelectedIndexChanged event with postback.
When the UserControl has been refreshed the caption is no longer Edit detail : 5 but Edit detail {0}.
Other parts of the usercontrol retain their values .

Yours
Björn

Can't anchor window to top of page...

Hi Everyone,

I upgraded from the ASP.Net RadWindow to the ASP.Net AJAX RadWindow, and now, when I dynamically add a window, the "top" property does not work...no matter what I try (and I've tried quite a few things...), the window opens up centered...
Help!!!

code:

    
                 Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles OpenerButton.Click 
        
                    Dim NewWindow As New Telerik.Web.UI.RadWindow 
        
                    With NewWindow 
        
                        .NavigateUrl = "http://www.telerik.com" 
        
                        .Title = "A RadWindow" 
        
                        .Modal = True 
        
                        .Height = Unit.Pixel(500) 
        
                        .Width = Unit.Pixel(500) 
        
                        .Top = Unit.Pixel(1) 
        
                        .InitialBehaviors = Telerik.Web.UI.WindowBehaviors.None 
        
                        .ReloadOnShow = False 
        
                        .VisibleOnPageLoad = True 
        
                        .VisibleStatusbar = False 
        
                        .EnableViewState = True 
        
                        .DestroyOnClose = True 
        
                        .ID = "ARadWindow" 
        
                        .Behaviors = Telerik.Web.UI.WindowBehaviors.Close 
        
                        .OnClientClose = "OnClientClose" 
        
                        .VisibleTitlebar = True 
        
                        .Visible = True 
        
                    End With 
        
                    RadWindowManager1.Windows.Add(NewWindow) 
        
                End Sub

aspx:

    
                <form id="form1" runat="server"> 
        
                <asp:Button ID="OpenerButton" runat="server" Text="Button" /> 
        
                <telerik:RadScriptManager ID="RadScriptManager1" runat="server">

                    </telerik:RadWindow> 
        
                </Windows> 
        
                </telerik:RadWindowManager> 
        
                </form>
