Hello,

I have a RadTreeView in a UpdatePanel and a RadListView in another UpdatePanel. I must expanded the parent nodes to the right childnode. When i clicked on the childnode, then i load a details from webservice in the ListView in the other UpdatePanel. This works fine.

The problem is, after i clicked on the childnode and loaded the details, the TreeView is unexpanded and the childnode is deselcted. How can I solve my problem?

Here is my code:

    
            <asp:UpdatePanel ID="UpdatePanel2" runat="server" onload="UpdatePanel2_Load">  
        
                        <ContentTemplate> 
        
                            <telerik:RadTreeView ID="rtvLayoutListe" runat="server" AutoPostBack="true" Height="450px"   
        
                                Skin="Office2007" OnClientNodeClicking="ClientClickHandler"    
        
                                oncontextmenuitemclick="rtvLayoutListe_ContextMenuItemClick"             
        
                                OnNodeClick="rtvLayoutListe_NodeClick"   
        
                                onclientcontextmenuitemclicking="ContextMenuClicking"   
        
            onclientnodeclicked="ClientClickedHandler"> 

                            .....                    </
 
ContextMenus>  
            
                </telerik:RadTreeView> 
            
            </ContentTemplate>  
            
</asp:UpdatePanel>

            ...

<
 
asp:UpdatePanel ID="UpdatePanel1" runat="server">  
            
<Triggers> 

            <asp:AsyncPostBackTrigger ControlID="rtvLayoutListe" EventName="NodeClick" /> 
 
</Triggers>  
<ContentTemplate>

            <h3><asp:Label ID="lblContainerNameH3" runat="server" Text=""></asp:Label></h3>  

            <telerik:RadListBox ID="rlbObjectList" runat="server" AllowDelete="True" AllowReorder="True" CssClass="rlbObjects" Skin="Office2007" Width="400px"  

            onitemdatabound="rlbObjectList_ItemDataBound">  
 
<ButtonSettings ShowTransfer="False" ShowTransferAll="False" /> 
</telerik:RadListBox>

            ...

Javascript:

    
            function ClientClickHandler(sender, eventArgs) {  
        
                        var node = eventArgs.get_node().get_value();  
        
                        if (!node.startsWith("container-")) {  
        
                            eventArgs.set_cancel(true);  
        
                            return false;  
        
                  }  
        
            }

C#:

    
            protected
 
void UpdatePanel2_Load(object sender, EventArgs e) 
            
{
    GenerateTreeView();
}
 
public 
 
void GenerateTreeView() 
            
{
rtvLayoutListe.Nodes.Clear(); 
 
layoutsql lsql = new layoutsql();  
 
DataSet ds = lsql.GetLayoutsForManager();   
 
            ...

            }

            protected void rtvLayoutListe_NodeClick(object sender, RadTreeNodeEventArgs e)  
        
                {  
        
                    if (e.Node.Value.StartsWith("container-"))  
        
                    {  
        
                        lblContainerNameH3.Text = "Container: " + e.Node.Text;  
        
                        objectssql osql = new objectssql();  
        
                        rlbObjectList.DataSource = osql.LoadCurrentContainers(int.Parse(e.Node.Value.Substring(10)));  
        
                        rlbObjectList.DataBind();  
        
                        lblContainerNameH3.Text += " - Time: " + new TimeSpan(0, 0, timecounter).ToString();  
        
                    }  
        
                    else  
        
                    {  
        
                        lblContainerNameH3.Text = "";  
        
                    }  
        
                }

I saw, after the click on the Node - the UpdatePanel makes a new load.

How can I prevent a reload of the UpdatePanel?

How to set the value of cell before update fires

Hello All,

I have the IP address of the user and I want to set one of the columns in the data source of the grid. In Pseudo code, I want to achieve the following

MyGrid . RowBeingUpdated . Column ("IPAddress).Value = "192.168.1.1";

Could someone advise which event I should use and the syntax to update the cell value. I have tried to get it working with DataKeyValues, but am not familiar enough yet to get it working.

I have included below the code that I used with the VS2008 default grid, and it works fine for that control.

Thanks in advance,

Mark Breen

oRec.CreatedByIPAddress = GetIPAddress();

Drag and drop RadGrid item in between RadTreeView nodes

Hi,

I'm using this example: http://www.telerik.com/community/code-library/aspnet-ajax/general/drag-and-drop-between-radgrid-and-radtreeview.aspx from the code library to drag and drop RadGrid rows to a RadTreeView. In this example it is only possible to drop a row onto a Node, but not in between two nodes.

Is there a solution to make this possible?

Thx,
Danny

Google-like filtering for RadListBox

Hi, I would like to implement Google-Like filtering in my ListBoxes just as you do in the Google-Like filtering example of the RadGrid. In other words, I would like to input some text in a textbox on top of the list box so that the list items that appear on the listbox depend on the text that is entered in the textbox.

I would appreciate any ideas or code to help me do this.

Thank you,
Manuel

Self Referencing Hierarchy Paging

I am using a self-referencing hierarchy with paging (nothing custom, just the built-in mechanisms). When I expand a parent item to show the children, the grid shows the parent's paging template inside it which is something I would rather not have happen. Is it possible to hide this on child records?

tooltip error using onajaxupdate in master page

I am using the q1 2009 version of tooltip (in VB) to create a user control that opens a tooltip from a javascript function (a dbl click on some text) and then loads a user control into the tooltip. The idea will be to feed the selected text into a database query in the new user control.

Currently this works fine when running in a stand-alone page but when it is added to a master page or template page
when the tooltip opens I get a javascript error: " LENGTH is null or is not an object"
I've tried numerous ideas and have tried to find some relevant references in the forums but have not found a fix that works yet.
What is the best way to avoid this error?

A basic version of the code used for the user control containing the tooltip manager is below:

<

script runat="server">

Protected Sub tooltipupdate(ByVal sender As Object, ByVal e As Telerik.Web.UI.ToolTipUpdateEventArgs)

Dim ctrl As Control = New Control

ctrl = Page.LoadControl(

"~/controls/usercontrol1.ascx")

e.UpdatePanel.ContentTemplateContainer.Controls.Add(ctrl)

End Sub

</

script>

<

div>

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

function showToolTip(element)

{

var searchString = "";

if (window.document.selection)

{

var rng = window.document.selection.createRange();

searchString = rng.text;

}

else if (window.getSelection)

{

searchString = window.getSelection().toString();

}

if (searchString)

{

var tooltipManager = $find("<%= RadToolTipManager1.ClientID %>");

if (!tooltipManager) return;

var tooltip = tooltipManager.getToolTipByElement(element);

tooltip = tooltipManager.createToolTip(element);

tooltip.set_value(searchString);

element.onmouseover =

null;

tooltip.show();

}

</script>

</telerik:RadScriptBlock>

<telerik:RadToolTipManager ID="RadToolTipManager1"

Width="400px"

height="200px"

RelativeTo="BrowserWindow"

Position="Center"

runat="server"

Onajaxupdate="tooltipupdate"

AutoTooltipify="false"

>

</telerik:RadToolTipManager>

</

div>

Error Deploying RadEditor Lite

I am trying to deploy the RadEditorMoss 4.5.4 version to a sharepoint farm. The farm has 2 web front ends with the cenrtral admin on one of the web front ends.

I can successfully add the solution to the farm, but when I try and deploy the solution to my web application I get the following error.

server1 : http://server1:22659/ : SharePoint - 22659 : Error: The copying of this file failed: RadControls/Editor/Localization/en-US/Tools.xml.
This operation uses the SharePoint Administration service (spadmin), which could not be contacted. If the service is stopped or disabled, start it and try the operation again.
server2 : http://server1:22659/ : SharePoint - 22659 : Error: The copying of this file failed: RadControls/Editor/Skins/Default/Dialogs/ImgExt/asf.gif.
This operation uses the SharePoint Administration service (spadmin), which could not be contacted. If the service is stopped or disabled, start it and try the operation again.
server2 : This operation uses the SharePoint Administration service (spadmin), which could not be contacted. If the service is stopped or disabled, start it and try the operation again.
server1 : This operation uses the SharePoint Administration service (spadmin), which could not be contacted. If the service is stopped or disabled, start it and try the operation again.

I have ensured that the Aministration service is running. And also have it running with an account with admin privilages on both web fronts ends.
I have noticed that it failes when trying to copy different files, but always fails on some file.

Just as a test I have also deployed the full RAD Moss RadEditorMOSS_5_2_3_Trial. That solution deployed successfully. There seems to be a problem specifically with this wsp.

Any help would be appreciated.
