Having RadTreeView pass custom variable to JavaScript AfterClientCheck event

I have several TreeViews on a page and I would like to have a single JavaScript function called by all of them (when a user checks an item). For example, I'll have a <div> tag on top of each TreeView. When the user clicks a checkbox in any of the TreeViews, the TreeView will fire an AfterClientCheck event to call the single function.  This function would then figure out what the div ID is for that TreeView and update the div text with the checkbox change.

When I create all these TreeViews, I'll somehow attach the ID of the <div> tag that lives above it. I've looked at attributes. But, I want to attach a single attribute (that holds the div's ID) to the whole TreeView. This attribute would hold the ID of the div tag.

Can I make an attribute for the entire TreeView? If not, how can I attach a custom value to the TreeView that can be read in its events?

Thanks

AjaxRequest not firing

Im using a RadWindow as an edit form for an ajax grid.
AjaxRequest isnt being fired when I insert data, which means the grid isnt updating on the parent form

In the Radwindow I have a button that calls the data insert function and closes the window

    
             InsertBandMember();  
        
                        ClientScript.RegisterStartupScript(Page.GetType(), "mykey", "CloseAndRebind('navigateToInserted');", true);

this calls the javascript function in the RadWindow edit form

    
            function CloseAndRebind(args) {  
        
                            GetRadWindow().Close();  
        
                            GetRadWindow().BrowserWindow.refreshGrid(args);  
        
                        }

this then calls the javascript function in the parent form (where the grid lives)

    
            function refreshGrid(arg) {  
        
                        debugger;  
        
                        if (!arg) {  
        
                            $find("<%= Telerik.Web.UI.RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest("Rebind");  
        
                        }  
        
                        else {  
        
                            $find("<%= Telerik.Web.UI.RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest("RebindAndNavigate");  
        
                        }  
        
                    }

and finally heres the Ajax Request event handler in the code behind

    
            protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)  
        
                    {  
        
                        if (e.Argument == "Rebind")  
        
                        {  
        
                            RadGrid1.MasterTableView.SortExpressions.Clear();  
        
                            RadGrid1.MasterTableView.GroupByExpressions.Clear();  
        
                            RadGrid1.Rebind();  
        
                        }  
        
                        else if (e.Argument == "RebindAndNavigate")  
        
                        {  
        
                            RadGrid1.MasterTableView.SortExpressions.Clear();  
        
                            RadGrid1.MasterTableView.GroupByExpressions.Clear();  
        
                            RadGrid1RadGrid1.MasterTableView.CurrentPageIndex = RadGrid1.MasterTableView.PageCount - 1;  
        
                            RadGrid1.Rebind();  
        
                        }  
        
                    }

This never gets called, but in the javascript, this line does

    
            $find("<%= Telerik.Web.UI.RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest("RebindAndNavigate");

Im using an ajax manager on a master page, so ive put an ajaxproxymanager on the grid page

    
            <telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">  
        
                    <AjaxSettings> 
        
                        <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">  
        
                                    <UpdatedControls> 
        
                                        <telerik:AjaxUpdatedControl ControlID="RadGrid1" /> 
        
                                    </UpdatedControls> 
        
                                </telerik:AjaxSetting>   
        
                        <telerik:AjaxSetting AjaxControlID="RadGrid1">  
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="RadGrid1"   
        
                                    LoadingPanelID="RadAjaxLoadingPanel1" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                    </AjaxSettings> 
        
                </telerik:RadAjaxManagerProxy>

Yet still the grid wont update. The data is being committed to the database, so how can I get the grid to do an ajax refresh ?

Strange Exception

Hi,
I've got an error in my application. I have a TextBox in my user control that every time I want to read from it i'll get error and I can't even watch the value and debug it, for example when I try to add the TextBox to Watch Variables it shows following message:

"Cannot evaluate expression because a thread is stopped at a point where garbage collection is impossible, possibly because the code is optimized. "

I would be happy if i have any answer from you
Best Regards
Nima

Strange Behaviour when style sheet is rolled back

Hi,

We are using Q3 release of Asp.Net Ajax controls. We modified some style sheet/ Skin and applied it to our controls grid, Scheduler. Something went wrong and we roll back the changes. The old Style sheet is not getting applied.

Do Rad controls keep a cache of Skins and Style sheets

AddHandler not firing in User Control

I am adding a radcombobox dynamically when certain parameters are met. This is happening inside an ajaxpanel in a user control. The code to add the combobox is as follows:

    
            Dim dropDownList As New RadComboBox  
        
            dropDownList.ID = associatedAttribute.Name  
        
            dropDownList.CssClass = "attributeDropdownList" 
        
            dropDownList.DataSource = associatedAttribute.AttributeItemCollection  
        
            dropDownList.DataTextField = "FormattedAmount" 
        
            dropDownList.DataValueField = "fldSkuSuffix" 
        
            dropDownList.DataBind()  
        
            dropDownList.Skin = "SkyBlue" 
        
            AddHandler dropDownList.SelectedIndexChanged, AddressOf dropDownList_SelectedIndexChanged  
        
            dropDownList.AutoPostBack = True 
        
            dropDownList.Items.Insert(0, New RadComboBoxItem("--Select--", String.Empty))  
        
            If associatedAttribute.IsRequired Then 
        
                Dim rfv As New RequiredFieldValidator()  
        
                rfv.ControlToValidate = dropDownList.ID  
        
                rfv.Display = ValidatorDisplay.None  
        
                rfv.ErrorMessage = String.Format("Please Select", associatedAttribute.Name)  
        
                pnlProductAttributes.Controls.Add(rfv)  
        
            End If 
        
            pnlProductAttributes.Controls.Add(dropDownList)

When the page is rendered, it is rendered correctly. So this all seems ok, except that the AddHandler is not firing. The code for the handler event is:

    
            Private Sub dropDownList_SelectedIndexChanged(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs)  
        
                    Dim dropDownList As RadComboBox = TryCast(sender, RadComboBox)  
        
                    If dropDownList IsNot Nothing Then 
        
                        Dim myLabel As Label = TryCast(ThisPage.cartUpdatePanel.FindControl(dropDownList.ID), Label)  
        
                        If myLabel IsNot Nothing Then 
        
                            myLabel.Text = String.Format("<strong>{0}:</strong>&nbsp;{1}<br/>", dropDownList.ID, dropDownList.SelectedItem.Text)  
        
                        End If 
        
                    End If 
        
                    Dim skuId As String = GetSku()  
        
                    GetInventory(skuId)  
        
                End Sub

The code in the event handler works as i have tested this with just a regular asp dropdownlist. Why will it not work for radcombobox?

[Solved] Pane will not show in FF

Hello,
I am having trouble displaying the splitter without borders with scroll bars to fit within the browser window. I want the pane to size with the window size. Can anyone look at my code and see where I am going wrong?
I have tried everything that I have found on these forums.
IE6 shows the panes and text but the browser has both scroll bars.
FF3 display the splitter bar only at about 40px high and the text in the paragraphs disappears right after the page has loaded.
Thanks

Adding Combobox to Menu Item

I have a normal, horizontal-looking menu with about 5 different main menu items -- I'd like to add a Combobox as the content for another menu item, and have this particular menu item aligned to the right of the whole menu. So, regardless of the width of the menu, the combobox menu item would always be on the far right. I've attempted to do this with little luck -- also, when adding a combobox, or any custom template to a menu item, the background is just white. I'm using the Black skin and would like to keep the background the same as all of the other menu items with just plain text... thank you for any help.

Child menu item link redirect based upon .net Role

Hello,

I am using Forms Authentication and ASP.NET roles for my website. For most of my menu links I will be able to use the NavigateUrl to open the proper pages. However, I need to be able to redirect users based upon their role for a few of the child items. For example, when an employee is in the parent branch named Employee and navigates to and clicks on the Forms child menu, I need all the users in the 'Doctors' role to be directed to ~/employee_login/doctors_area/forms.aspx and users in the 'Office_Staff' role to be directed to ~/employee_login/office_staff_area/forms.aspx page. I am able to accomplish this with the onclick event using a standard asp:LinkButton for example (see code below) but am unable to find a way of doing it using the RadMenu. Please help.

<

form id="form1" runat="server">

<div>

<asp:LinkButton ID="LinkButton1" runat="server" onclick="redirectDocStaff">LinkButton</asp:LinkButton><script runat="server"> protected void redirectDocStaff(object sender, EventArgs e)
