Hi,

I have used a Rad tree in my application. I used skin "Web20" for the tree control.
For all leaf nodes on mouse hover i want to changed the mouse cursor type. How can i do this?

Also how can i know default css setting applied on a rad tree view for a parrticular skin? Is this documented any where so that i can customize them as i want.

Please provide me some information on the above.

Thanks,
Nataraj

About rad grid

Hi,

I am using hierarchical grid.In this in commandItemTemplate i have one link button.Instead of having on grid row i want this linkbutton below each row of the parent grid.On this link btn i want to show popup form.and to this popup i wat to send the id of first row of grid.
If we are having link button on grid row itself then it is easy to pass the grid row id to link button.But as my link btn is nt on grid i am not able to pass the id of first row of grid.

Select the first leaf node of a tree

Hi,

I have a Rad tree view bound to a dataset. When page loads, i want to display the tree view with the first leaf node in the tree structure. for Eg:
Consider tree has the following structure:
A:-
    A1:-
        A11:-
            A111
            A112
            A113
        A12:-
            A121
            A122
        A13
    A2:-
        A21:-
            A211
            A212:-
                A2121
        A22
    A3
B:-
    B1:-
    so on...

when page loads i want to show the user node A11 selected and also parent nodes for A11 expanded.(if A11 has no child nodes then A11 has to be selected as it will be first leaf node) How can i do this server side?

I tried to do it by loops but i am not successful to traverse through the nodes at diefferent levels.

Please help me.

Thanks in advance,

RadToolbar Javscript Error

I have a RadToolbar that is created using the following code:

                                <telerik:RadToolBar ID="RadToolBar1" runat="server" OnButtonClick="RadToolBar1_ButtonClick"         
                            CssClass="Toolbar" Skin="WebBlue" OnClientButtonClicked="ToolbarButtonClicked">         
                            <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>         
                            <Items>                             
                                <telerik:RadToolBarButton runat="server" ImageUrl="~/Images/new_note.png" Text="Notes">         
                                </telerik:RadToolBarButton>                           
                            </Items>         
                        </telerik:RadToolBar>         

I also have a a RadDock on the same page:

                    <telerik:RadDockLayout ID="RadDockLayout1" runat="server" EnableAjaxSkinRendering="False"         
                            EnableEmbeddedBaseStylesheet="False" EnableEmbeddedSkins="False">         
                            <telerik:RadDockZone ID="DocumentDockZone" runat="server" Height="105%" Width="100%"         
                                FitDocks="False" bgcolor="#666666" BackColor="#666666" BorderStyle="None" BorderWidth="0px">                             
                                <telerik:RadDock ID="NotesDock" runat="server" Width="99%" Skin="Office2007" DefaultCommands="ExpandCollapse"         
                                    DockHandle="None" Title="Notes" DockMode="Floating" ForbiddenZones="DocumentDockZone">         
                                    <ContentTemplate>         
                                        <uc5:Notes ID="Notes1" runat="server" />         
                                    </ContentTemplate>         
                                </telerik:RadDock>         
                            </telerik:RadDockZone>         
            </telerik:RadDockLayout>        

I have the following javascript code on the same page:

                            function ToolbarButtonClicked(sender, args)          
                    {         
                        var button = args.get_item();         
                        var notesDocks = $find("<%= NotesDock.ClientID %>");         
                                 
                        if (button.get_text() == "Notes")          
                        {         
                                     
                            alert("Notes click");         
                            args.set_cancel(true);         
                                     
                        }         
                    }          

When the page attempts to load I get the following Exception:

System.Web.HttpException: "Error executing child request for Default.aspx."

InnerException: System.Web.HttpUnhandledException: "The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)."

This error only occurs when I attempt to get the NotesDock control in the javascript line "var notesDocks = $find("<%= NotesDock.ClientID %>");" But I need a reference to this object because I want to call notesDock.set_closed(false) at some point.

Any idea what might be causing this problem?

Overiding ExpandColumn Control title attr (server side)

Is there a proper way to override the 'Expand' and 'Collapse' values for the title attribute in the <input> control for the ExpandCollapse column when looking at hierarchical data in RadGrid?

I've tried the following during the OnDataBound event, but the title attribute shows up twice. Once with the radgrid value and then mine. Can I even access the opaque(?) object that has these values in it?

BTW, setting the tooltip for the parent <td> element works just fine.

protected void OutsideLawFirmGrid_OnDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = e.Item as GridDataItem;
            item["ExpandColumn"].ToolTip = "View Contacts";
            System.Web.UI.WebControls.Button btn = (System.Web.UI.WebControls.Button)item["ExpandColumn"].Controls[0];
            btn.Attributes.Add("title", "View Contacts");
            btn.ToolTip = "View Contacts";
        }
    }

Is there some later stage on the server where I can intercept things and iteratate over all the GridDataItems and replace this value? I tried to place an iterative version of this in the Page_PreRender w/the same results.
