Question

I’ve created one usercontrol in vs2010 professional . The usercontrol is from DevExpress.
I’ve used usercontrol’s load() event. And i used xml file for my usercontrol application. In usercontrol i’ve added DevExpress xtraTreeList control & i populated nodes of xtraTreeList by using my xml file. My xml file is present in my applications directory path means- E:\MsgBlasterApplicationtemp\MsgBlasterApplication\bin\Debug\Database .
When i’m drag & drop my usercontrol in my form then it gives me error. The error is as follows–

Failed to creste component ' TreeListUserControl'. The error message follows:
'System.IO.DirectoryNotFoundException:Could not find part of path.

This is the default behavior and you will reproduce it if you use the standard GridView on the standard UserControl. When the UserControl is positioned on a form, all controls on it work as if the application runs :(. Here is the solution which should work fine for you:

    private void XtraUserControl1_Load(object sender, EventArgs e) {
        if(!DesignMode) {
            // your code to populate the treeList with data
         }
    }
