How to rebind the tree view control with changed/edited nodes ?

Hi,
I am using two tree view control . From the left tree view control I am dragging and dropping nodes to the right side tree view control also I am editing the nodes of the right side tree view control . I want something like that , I will put a button and when I clicked on that button I will rebind the right side tree view control with the newly added nodes forn the left tree view or edited nodes with the same heirachical manner . I mean to say if I have edited the 3rd child node out of four child nodes of a parent node then when I clicked on that button it should display the parent node and 3rd child node . Same for the newly added node parent node\child nodes .

Also If click on "Cancel" button it should revert back the changes which I made to both the tree view control.
Can you please suggest me how can I do this ?

With Thanks & Regards
Manoj

RadRotator with Output Caching

Hello

I have a user control that has a RadRotator. On the user control, I have SQL OutputCache Dependancy. When I put one instance of my control on the page with caching, everything works as expected.

When my page has two of those controls with caching, when the page is first rendered, everything is fine. If i refresh the page and page is created from cache, I get the following javascript error:

Error: 'Telerik' is undefined
Line 661

//<![CDATA[

Sys.Application.add_init(

function() {

Line661:

$create(Telerik.Web.UI.RadRotator, {

});

Sys.Application.add_init(

function() {

$create(Telerik.Web.UI.RadRotator, {

});

Sys.Application.initialize();

NodeClick and MultipleSelect='true' not firing

Hi,

When a TreeView has MultipleSelect='true' the Control+Click node selections are not being fired.

I think this is a recent bug as this used to work in older versions of the Telerik.Web.UI library (Not sure which version started this bug).

This is very easy to reproduce. Eg:

Thanks

Guido Tapia

<

div>

<telerik:RadScriptManager ID="sm" runat="server" />

<telerik:RadStyleSheetManager ID="RadStyleSheetManager1" runat="server" />

protected void RadTreeView1_NodeClick(object sender, RadTreeNodeEventArgs e)

{

lblClicked.Text = e.Node.Text +

" CLICKED";

}

</script>

<asp:Label runat="server" ID="lblClicked" />

<telerik:RadTreeView ID="RadTreeView1" runat="server" Height="400px" Width="300px" EnableDragAndDrop="true"

Skin="Office2007" OnNodeClick="RadTreeView1_NodeClick" MultipleSelect="true">

<Nodes>

<telerik:RadTreeNode Text="Arts" />

<telerik:RadTreeNode Text="Biographies" />

<telerik:RadTreeNode Text="Children's Books" />

[Solved] Client-Side Methods Not Working

Hello,

I tried programmably setting the selected index or value of the RadComboBox, but neither work. I do:

combo.set_selectedIndex(0); //doesn't do anything (has way more than zero items)

OR

var item = combo.findItemByValue("Value"); //returns actual instance
item.set_selectedItem(item); //doesn't do anything

What do I have to do to update the display??? Is there an update method? Or am I missing something. Again, the combo has plenty of items and the findItemByValue returns a valid reference.

Thanks.
