Hi All

I have moved the RadTreeView to a UC.

How i wish that when the user clicks on a node, the event is bubbled to the main page, and then the RadGridView is bound.

At the moment in the UC, I have the following:-

protected void RadTreeView1_NodeClick(object sender, RadTreeNodeEventArgs e)
    {
        //lblError.Visible = false;
        //lblError.Text = "";
        RadTreeNode nodeEdited = e.Node;
        ViewState["nodeLevel"] = e.Node.Level;
        ViewState["FullPath"] = e.Node.FullPath;
        ViewState["Value"] = e.Node.Value;
        //pnlCrawledBuildDetailExtended.Visible = false;
        BindGridView();
    }

How can I bubble the BindGridView() to the Main Page, and bind the gridview on the main page?

Thanks for your help

Johann

Hey Johann,

This forum post from forums.asp.net seems to do the trick, I even like the approach they used on it. :)

Bubble Event from UserControl

Let us know if that works for you!

Hi Serrin

I saw that example already to tell you the truth, and would work for normal controls.

However my problem is, for example, how to add an event handler to the NodeClick of the RadTreeView?

I tried something like

RadTreeView1.NodeClickEvent += new EventHandler(RadTreeView1_NodeClick);
But no success.

I would like to see an example of a RadTreeView UC

Thanks for your help

Hello Johann,

The name of the event is NodeClick not NodeClickEvent.

Hi Albert

I tried this

        this.Load += new EventHandler(this.Page_Load);
        RadTreeView1.NodeClick += new Forms_Client.NodeClickDelegate(RadTreeView1_NodeClick);

However its throwing an error:-

Error    117    'ASP.controls_productsradtreeview_ascx' does not contain a definition for 'NodeClick' and no extension method 'NodeClick' accepting a first argument of type 'ASP.controls_productsradtreeview_ascx' could be found (are you missing a using directive or an assembly reference?)    C:\Enlistments\QuintDevelopers\private\Website\TestProductRadGridView.aspx.cs    20    22    C:\...\Website\
Error    118    The type or namespace name 'Forms_Client' could not be found (are you missing a using directive or an assembly reference?)    C:\Enlistments\QuintDevelopers\private\Website\TestProductRadGridView.aspx.cs    20    39    C:\...\Website\
