    data
    text
    <p>I have a userControl (.NET 1.1 Winforms) that has a clickable picturebox as a button.</p> <p>Since I have lots of those usercontrols visible at the same time, I thought It could be nice if I just display the picture box when the mouse is over the usercontrol and hide it otherwise.</p> <p>To do so, I handle the MouseEnter and MouseLeave events of the UserControl, hiding and displaying the picturebox. That works fine.</p> <p>But when the clickable picturebox is visible I'm not longer able to click it (the hand cursor is gone and the click event is not firing).</p> <p>After some test, I realize that if comment all content on the MouseLeave handler that do something with my picturebox... this way the picturebox is clickable.</p> <p><strong>I'm not using the correct event?</strong></p> <p><strong>There's another way to accomplish this?</strong></p> <p>Here is the code...</p> <pre><code>Private Sub NodoEstablo_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.pictAdd.Visible = False End Sub Private Sub NodoEstablo_MouseEnters(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.MouseEnter Me.pictAdd.Visible = True End Sub </code></pre> <p>The problematic event handler:</p> <pre><code>Private Sub NodoEstablo_MouseLeaves(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.MouseLeave Me.pictAdd.Visible = False End Sub </code></pre> <p>Update: If I resize the picturebox on MouseLeave (just to do something) it works. So far, changing Visible and Location in the MouseLeave prevent me for click the picturebox. :S</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
