Hello,

This is very weird, I really do not see any reasons why  <%= uwtNavigation.ClientID %> should not be working. Is it possible that the javascript is somehow out of the scope of the page.. I really do not know.

Hardcoding the ID is fine, as long is the layout of the page is not changed, since changing the layout may change the ClientID of the tree.

The problem was when retrieving the name of the tree:

--------------------------------------------------------

tree = igtree_getTreeById("<%= uwtNavigation.ClientID %>");

--------------------------------------------------------

I have substituted it with

--------------------------------------------------------

tree = igtree_getTreeById("ctl00uwtNavigation");

--------------------------------------------------------

where ctl00uwtNavigation is the name of the owtNavigation control after rendering, in the HTML page.

Still I don't understand why the function igtree_getTreeById("<%= uwtNavigation.ClientID %>") doesn't retrieve nothing. Do I need to put some references?

Cheers,

C.

Hi Ivan,

I followed the "CSOM way" in order to get the focus to the ultrawebtree control, as it follows:

- I have added a dummy control which can implement the accesskey, for example a textbox, And I have setted the Accesskey property.

As I didn't succeed to set the focus on the Ultrawebtree (as a whole) either by c# code or by CSOM, I will select the first node in the tree instead of setting the focus on the webtree.

- I have declared in a .js file the following function:

------------------------------------------------------------------

var tree;

var nodes;

var node; 

function SetFocusOnWebTree()

{

   try

   {

      tree = igtree_getTreeById("<%= uwtNavigation.ClientID %>");

      nodes = tree.getNodes();

      node = nodes[0];

      node.setSelected(true);

   }

   catch(err)

   {

      alert(err.description);

   }

}

-----------------------------------------------------------------------------

- back on our aspx page, I register the .js file:

---------------------------------------------------------------------------- 

protected void Page_Load(object sender, EventArgs e)

{

   if (!Page.ClientScript.IsClientScriptIncludeRegistered("MyFunctions"))

   {

      Page.ClientScript.RegisterClientScriptInclude("MyFunctions", ResolveClientURL("~/UI/Assets/MyFunctions.js"));

   }

}

-----------------------------------------------------------------------------------

- I am addind the atribute "onfocus" to the dummy textbox control

-----------------------------------------------------------------------------------

protected void txtDummy_PreRender(object sender, EventArgs e)

{

this.txtDummy.Attributes.Add("onfocus", "SetFocusOnWebTree()");

}

Running the page, I am pressing the accesskey keys, and I receive the following error message:

-------------------------------------------------------------------------------------

'tree' is null or not an object

-------------------------------------------------------------------------------------

 which means that the problem is on the CSOM part.

How can I select a node with the CSOM? Can you post a sample?

Thank you,

C.

 Hi Ivan,

These articles are not a direct answer to my question.

UltraWebTree control has a method called Focus(). How can I make this method work? Also, how can made functional the Accesibility features on the webtree?

Thank you,

C.
