Hello,
I tried moving all of the JavaScript functions out to an external file and reference it like this:
and none of the functions work. The script file is in my web project directory. When I examine with IE Developer Toolbar, I see error messages with my vars set to null when the functions are called:
for example:
tree is null
However, when I include the script inside my aspx page, everything works.
What am I doing wrong?
Best Regards,
Alex

Hi Alex,
How the "tree" variable is initialized?

Hi Vlad,
This is my code:
and the .aspx tree definition:
This is the call stack from Firebug:
The down arrow functionality works when I inline my scripts inside the .aspx page.
I commented out the other script errors which were reporting prior to the "tree is null" to isolate this error.
Best Regards,

This is my code:
| function OnKeyPressingInTree(sender, eventArgs) |
| { |
| // var node = eventArgs.get_node(); |
| // var key = eventArgs.get_domEvent().keyCode; |
| var key = eventArgs.get_domEvent().keyCode; |
| if(key == "40") // down-arrow |
| { |
| var tree = $find("<%= RadTreeView1.ClientID %>"); |
| var node = tree.get_selectedNode(); |
| var nextNode = node.get_nextNode(); |
and the .aspx tree definition:
| <telerik:RadTreeView ID="RadTreeView1" runat="server" Style="position: relative; |
| top: 0px; left: 0px;" AllowNodeEditing="True" BorderColor="Black" EnableDragAndDrop="True" |
| OnNodeDrop="RadTreeView1_NodeDrop" Skin="Telerik" BorderStyle="Solid" BorderWidth="1px" |
| MultipleSelect="True" Width="100%" OnNodeDataBound="RadTreeView1_NodeDataBound" |
| OnClientNodeDragStart="OnClientNodeDragStartHandler" OnClientMouseOver="onMouseOver" |
| OnClientMouseOut="onMouseOut" OnClientNodeClicked="OnClientNodeClickedHandler" |
| OnClientNodePopulating="nodePopulating" TabIndex="1" Height="100%" OnClientKeyPressing="OnKeyPressingInTree"> |
| <WebServiceSettings Path="MyWebService.asmx" Method="GetTreeViewNodes" /> |
| <ContextMenus> |
| ... |
This is the call stack from Firebug:
| tree is null |
| OnKeyPressingInTree(Object _element=div#RadTreeView1.RadTreeView, Object _cancel=false _node=Object _domEvent=Object)MyScriptFile.js (line 129) |

Hi Alex,
This line will work only if you use it on the page:
var tree = $find("<%= RadTreeView1.ClientID %>");

Vlad,
Yes, you are right, of course - the <% %> tags... Is there an equivalent functionality alternative I can use for that so that I could put the script in a separate file?
Thank you,
Alex

Hi Alex,
You can put everything else in the external script file except "tree" variable.

Vlad,
I found out that you don't have to use the asp.net surround tags in the external script:
var tree = $find("RadTreeView1");
This worked for me.
Thank you for your help,
Alex

Keep in mind this won't work if the control is placed inside another control using INamingContainer interface eg. MasterPage/ContentPage, WebUserControl or most composite controls such as RadGrid. If you only have the control on an .aspx page with no master page then you are safe.

Thank you for pointing this out. Do you know of a work-around?
What if I give the controls unique names, i.e. containerRadGrid1, radGrid1, etc..?

Alex
