Context Menus with TX Text Control .NET

A context menu is a very helpful feature to provide end users with information or menu options at a specific text position.

For example, a context menu for adding additional field information could be shown, but only if the user clicks on a field.

This week, we would like to show you how to create a very simple context menu.

When an end user right clicks, a menu will be displayed that offer the actions Cut, Copy and Paste. Only the possible menu entries will be shown.

For example, a Copy menu will be only shown, if a part of the text has been selected by the user.

Private Sub TextControl1_MouseUp(ByVal sender As Object, ByVal_
	e As System.Windows.Forms.MouseEventArgs) Handles TextControl1.MouseUp
 
    Dim pos As System.Drawing.Point
 
    If e.Button = MouseButtons.Right Then
        MenuItem3.Visible = TextControl1.CanCopy
        MenuItem4.Visible = TextControl1.CanPaste
 
        If TextControl1.Selection.Length = 0 Then
            MenuItem2.Visible = False
        Else
            MenuItem2.Visible = True
        End If
 
        pos.X = e.X
        pos.Y = e.Y
        ContextMenu1.Show(TextControl1, pos)
    End If
 
End Sub

We use the TX Text Control MouseUp event to intercept the end user's right mouse click. The Visible property of the different menu entries can be used to hide functionality that is currently not possible. Finally, the context menu will be shown at the X and Y position returned by the MouseUp event.

At least TX Text Control .NET trial version and Visual Studio .NET is required to test this sample.

New White Paper: Benefits of Web Based Business Applications

We have discussed the benefits of web based applications at length in the last few weeks. This paper summarizes the points that we have raised and presents some more interesting arguments.

The paper shows the benefits of web based intranet and Internet applications. It illustrates how employees and clients can access templates on a corporate network to create business correspondences using TX Text Control based technologies.
