Hi All,

I have tree view node after select event like below.

private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{
ifcViewerWrapper._treeData.OnAfterSelect(sender, e);

}
So i need call that event in my my method.

C#

private void FindRecursive(TreeNode treeNode)
    {
        foreach (TreeNode tn in treeNode.Nodes)
        {
          
            if (tn.Text.Contains(this.toolStripTextBox1.Text))
            {
               
//call the  treeView1_AfterSelect event
            }
            FindRecursive(tn);
        }
    }

can some one help me to do this

Regards

I can't understand what you are asking: what is the connection between the code shown in the AfterSelect EventHandler and the recursive find procedure ? What are you trying to do here ?

I just need to run the method (fcViewerWrapper._treeData.OnAfterSelect(sender, e)) inside the treeView1_AfterSelect.

the implementation of this mothod is

public void OnAfterSelect(object sender, TreeViewEventArgs e)
{
if (e.Node.Tag == null)
{
// skip properties
return;
}

if (e.Node.ImageIndex != IMAGE_CHECKED)
{
// skip unvisible & not referenced items
return;
}

_ifcViewer.SelectItem((e.Node.Tag as IFCTreeItem).ifcItem);
}

Your OnAfterSelect code looks fine; what's the problem calling this method from the TreeView AfterSelect EventHandler ?

Might be helpful here if you describe what the IFCViewer is and its relationship to your application, and the TreeView.

What to you mean by "calling a tree note"? There is no such concept; this is not a method, function, procedure, subroutine, property or operator.

You don't "call" event handlers: to use the "proper" mechanism to get into the handler, the event needs to be raised properly - which you can't do since there is no mechanism within a TreeView to artificially "raise" and event when it didn't really happen.

Instead, remove the code from your event handler into a "normal" method and call that with the appropriate parameter value - the Node in your case.
