How To

Resize an ActiveX control in RadForm

Problem

Currently RadForm does not resize ActiveX controls that are anchored or docked inside the form. For example this issue occurs when a WebBrowser is dropped on a RadForm and the form is maximized at run time.

Solution

The solution is to resize the *ActiveX *control when resizing the form:

1. Set an appropriate size for your *ActiveX *control.

this.webBrowser1.Size = new System.Drawing.Size(1024, 768); 

2. Process the *Resize *event of the form.

Resize += new System.EventHandler(this.frmWindow_Resize); 
private void frmWindow_Resize(object sender, EventArgs e) 
{ 
    Point pt = (Point)this.Size; 
    radTitleBar1.Width = pt.X; 
    webBrowser1.Width = pt.X - 20; 
    webBrowser1.Height = pt.Y - 30; 
} 

The above code snippet will allow you to expand and contract the window by using the form's handles or using the Maximize/Restore on the title bar. If you have a custom title bar, this code will also allow it to resize according to the window size.
