How to get checked nodes of RadTreeViewControl from RadWindow?

[jasear]

Hi,

I have a control on a normal aspx page. Next to it I have a button. I click on this button and it opens up a RadWindow. In the RadWindow I have a RadTreeViewControl in which I have checkboxes enabled. Once the user selects the appropriate checkboxes they click on the submit button which closes the rad window and should update the parent window.

However I cannot get the values for the checkednodes in the parent window. When I try tree.get_checkedNodes().length I get the correct int number that represents how many nodes are checked. However I am not sure on how to get the text for the checked nodes.
I want print out the text of the checked nodes in the parent window based on what was selected in the RadWindow.

Hi jasear,

Try the following code snippet to get the checked node text of the RadTreeView (which is inside the child window) in the Parent page on closing the child window.



//Page loading inside the Child window

ASPX:

 <asp:Button ID="Button1" runat="server" OnClientClick=" GetRadWindow();" Text="Button" /><br />



        <telerik:RadTreeView ID="RadTreeView1" CheckBoxes="true"   EnableDragAndDrop="true" EnableDragAndDropBetweenNodes="true" runat="server">
         <Nodes>
           <telerik:RadTreeNode Text="Node1"  >
            <Nodes>
              <telerik:RadTreeNode Text="Child1" ></telerik:RadTreeNode>
               <telerik:RadTreeNode Text="Child2" ></telerik:RadTreeNode>
            </Nodes>
           </telerik:RadTreeNode>
           <telerik:RadTreeNode Text="Node2" >
           <Nodes>
              <telerik:RadTreeNode Text="Child1" ></telerik:RadTreeNode>
               <telerik:RadTreeNode Text="Child2" ></telerik:RadTreeNode>
            </Nodes>
           </telerik:RadTreeNode>
           <telerik:RadTreeNode Text="Node3" >
           <Nodes>
              <telerik:RadTreeNode Text="Child1" ></telerik:RadTreeNode>
               <telerik:RadTreeNode Text="Child2" ></telerik:RadTreeNode>
            </Nodes>
           </telerik:RadTreeNode>
         </Nodes>
        </telerik:RadTreeView>

JS:

<script type="text/javascript" >

function GetRadWindow()

{

var oWindow = null;

if (window.frameElement)

{

oWindow = window.frameElement.radWindow;

oWindow.close();

}

}

//function to get the checked node text of TreeView

function GetCheckNodes()

{

var tree=$find("<%= RadTreeView1.ClientID %>");

var nodes=tree.get_nodes();

for (i=0; i<nodes.get_count(); i++)

{

if (nodes.getNode(i).get_checked())

{

alert(nodes.getNode(i).get_textElement().innerHTML)

}

}

}

</script>

//Parent page

ASPX:

  <telerik:RadWindow ID="RadWindow1" runat="server" OnClientClose="Close" ></telerik:RadWindow>

          <input id="Button2" type="button" value="ShowWindow" onclick="GetRadWindow();"  />

JS:

<script type="text/javascript" >
function GetRadWindow()
{
    var oWnd = $find("<%=RadWindow1.ClientID%>");
    oWnd.setUrl('Test.aspx');
    oWnd.show();

}

function Close()
{
  var oWnd =  $find("<%=RadWindow1.ClientID%>");

 //calling the client function from the page that is loaded inside the child window
 oWnd.get_contentFrame().contentWindow.GetCheckNodes();

}
</script>
