Hi there,

I was able to connect to my hierarchical sql data according to demo
http://demos.telerik.com/aspnet-ajax/treeview/examples/programming/databinding/defaultcs.aspx.

Now I need to transfer the items between two TreeViews, similar to the demo below except for the demo is using ListBoxs:
http://demos.telerik.com/aspnet-ajax/listbox/examples/functionality/transfer/defaultcs.aspx

But I need to keep the hierarchy information during transfer. Say, if the item belongs to group1 in TreeView1, it will also be shown as group1 item in TreeView2 after transfered to TreeView2.

TreeView2 is blank at first, after finished selecting data from TreeView1, I would like to write everything in TreeView2 to database with hierarchy info.

How could I accomplish that?

Thanks,
Di

RadWindow opened with <asp:Button> but NOT OPENED with <telerik:RadToolBarbutton>. Why?

Hi all, I have in the same page.aspx a RadToolBar with its RadToolBarButton and a simple <asp:Button>.
In this page I have also a simple RadWindow so defined:

    
            <telerik:RadWindowManager ID="RadWinMngr" runat="server"> 
        
                <Windows> 
        
                    <telerik:RadWindow ID="RadWindowAddUser" runat="server" NavigateUrl="http://www.google.com" VisibleOnPageLoad="true" Visible="false" /> 
        
                </Windows> 
        
            </telerik:RadWindowManager>

In the code behind, for the simple <asp:Button> I have:

    
            Private Sub Button1_click(...) 
        
                RadWindowAddUser.Visible = True 
        
            End Sub

and for the RadToolBarButton I have:

    
            Private Sub AddUser() 
        
                RadWindowAddUser.Visible = True 
        
            End Sub

I'm sure that the AddUser sub is correctly called because I've verified it by debug breakpoint.

The problem is that when I click on <asp:Button> the RadWindowAddUser is shown correctly, but when I click on RadToolBarButto it doesn't!
Why???

Anybody can help me? Thanks.

for each loop to display a treeview

I'm pretty new at this so I don't know much about how to use this or the proper way to call things so I apologize if I don't explain it very well.
Use this picture for reference: http://i178.photobucket.com/albums/w270/marcoshid/Other/Ethernet_View.jpg

I'm trying to make a treeview that will display the nodes '01', '02', etc one right under the other without the black node that is currently above the '02' node. Here is my code for it:

Eth_Rel ethernet_1 = new Eth_Rel();

protected void Ethernet_Load(object sender, EventArgs e)

{

RadTreeNode aParent = new RadTreeNode();

aParent.Text = "Ethernet Connection";

using (MapTest.Model.Computer_InventoryEntities context = new Computer_InventoryEntities())

{

int _roomID = 10;

var list = (from c in context.Eth_Rel where c.rm_id == _roomID select c).ToList();

string temp=null;

int id=999999;

// string etherName = null;

foreach ( Eth_Rel eth in list)

{

RadTreeNode ethernet = new RadTreeNode();

RadTreeNode ethernet1 = new RadTreeNode();

RadTreeNode panel = new RadTreeNode();

RadTreeNode panel1 = new RadTreeNode();

if ((temp != eth.SocketReference.Value.sck_pnl))

{

ethernet.Text = eth.Room.rm_code + " - " + eth.SocketReference.Value.sck_pnl;

panel.Text = "0" + eth.pnl_id.ToString();

RadTreeNode speed = new RadTreeNode();

speed.Text = "Speed: " + eth.SpeedReference.Value.spd_type;

panel.Nodes.Add(speed);

RadTreeNode connects = new RadTreeNode();

connects.Text = "Connects to: " + eth.ComputerReference.Value.comp_name;

panel.Nodes.Add(connects);

RadTreeNode location = new RadTreeNode();

location.Text = "Location: " + eth.LocationReference.Value.loc_name;

panel.Nodes.Add(location);

}

if ((temp == eth.SocketReference.Value.sck_pnl && id != eth.pnl_id))

{

panel1.Text = "0" + eth.pnl_id.ToString();

RadTreeNode speed = new RadTreeNode();

speed.Text = "Speed: " + eth.SpeedReference.Value.spd_type;

panel1.Nodes.Add(speed);

RadTreeNode connects = new RadTreeNode();

connects.Text = "Connects to: " + eth.ComputerReference.Value.comp_name;

panel1.Nodes.Add(connects);

RadTreeNode location = new RadTreeNode();

location.Text = "Location: " + eth.LocationReference.Value.loc_name;

panel1.Nodes.Add(location);

}

else

{

}

ethernet.Nodes.Add(panel);

aParent.Nodes.Add(ethernet);

ethernet.Nodes.Add(panel1);

aParent.Nodes.Add(ethernet);

temp = eth.SocketReference.Value.sck_pnl;

id = eth.pnl_id;

}

RadTreeView3.Nodes.Add(aParent);

Thanks for the help in advance,
Marcos H.

Firefox 4.0 not firing CommandItems

Standard Grid via LINQ DS
<telerik:GridButtonColumn ButtonType="ImageButton" CommandName="Delete" ConfirmDialogType="RadWindow" ConfirmText="Are you sure? Delete means delete." />

Protected Sub ReportGrid_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles ReportGrid.ItemCommand

If e.CommandName = "Delete" Then

Dim filepath As String = (CType(e.Item, GridDataItem)).OwnerTableView.DataKeyValues(e.Item.ItemIndex)("Doc_Path").ToString

If System.IO.File.Exists(Server.MapPath("/Files/" & filepath)) Then

System.IO.File.Delete(Server.MapPath("/Files/" & filepath))

End If

End Sub

Fires every time faithfully in IE 7. In FF 4.0 it fails miserably. Ideas/Workarounds?
