Hi Friends,

Code:

C#

private void treeView_AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e)
{
   StatusBar.text = "Loading Files";
   //ArrayList files1,ListView ListView1
   filllist(files1, ListView1);
   StatusBar.text = "List contains X Items";
}

After clicking a node in treeview control application waits to load the items. But in case there is another click on the control, and loading node will go invisible mode.

My question is how to temporarily disable treeview control untill the first click job is over? I tried Treeview.enable = false; and SuspendLayout property. But no use :(
Hope my question make sense.

0) Use a thread for the "loading" stuff that happens

1) In the "clicked" event handler for the list control, see if the loading thread is still running. If it is, don't do anything.

2) Or, while the thread is running, disable the list control (I'd probably do it this way).

You can try this

private void treeView_AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e)
{
treeView.Enabled=false;

StatusBar.text = "Loading Files";
//ArrayList files1,ListView ListView1
filllist(files1, ListView1);
StatusBar.text = "List contains X Items";
treeView.Enabled=true;

}
