splitter click event

[PR]

Hi,
I am trying to trigger the event click on a splitter.
I tried with this code:

AddHandler RadSplitContainer1.Splitters(0).Click, AddressOf SplitterClick

But nothing happens.
Do you have any advice?

I'm using RadControls 2013Q3.
Thanks

Hi Patrice, 

Thank you for writing us. 

If you need capture the click event of certain splitter you can subscribe to the MouseDown event of the SplitterElementLayout. You can use the following code sample: 

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

       'Subcribe for MouseDown event

       AddHandler Me.RadSplitContainer1.Splitters(0).Layout.MouseDown, AddressOf Layout_MouseDown

 

       ' Or set the NotifyParentOnMouseInput property to true and subscribe for MouseDown event.

       Me.RadSplitContainer1.Splitters(1).Layout.NotifyParentOnMouseInput = True

       AddHandler Me.RadSplitContainer1.Splitters(1).MouseDown, AddressOf Form1_MouseDown

   End Sub

 

   Private Sub Layout_MouseDown(sender As Object, e As MouseEventArgs)

       'Handle event

       Me.RadLabel1.Text = "Layout_MouseDown " & DateTime.UtcNow

   End Sub

 

   Private Sub Form1_MouseDown(sender As Object, e As MouseEventArgs)

       'Handle event

       Me.RadLabel2.Text = "Form1_MouseDown " & DateTime.UtcNow

   End Sub

The NotifyParentOnMouseInput property is indicating whether the element should pass the handled mouse event to the first parent element.
 
If you need to capture the click event you can subscribe for the Click event of the RadSplitContainer. This event is fired each time when a splitter is clicked: 

Private Sub RadSplitContainer1_Click(sender As Object, e As EventArgs) Handles RadSplitContainer1.Click
    Me.RadLabel3.Text = "RadSplitContainer1_Click " & DateTime.UtcNow
End Sub

If this is not what you are looking for, please send me detailed explanation of what you want to achieve.

Do not hesitate to write back with further questions.

This is perfect thank you!

Sorry, but I have one last question.

In fact, I just want to click on the splitter to reduce / enlarge my first panel.
But if the panel is collapsed I can not see the splitter.
Is there a setting to see the splitter when the first panel is collapsed?

Hi Patrice, 

The splitters will be hidden when they are not needed, hence they cannot remain visible in this case. To achieve your scenario, perhaps you can consider using RadDock with couple ToolWindows which support auto-hide capability. You can also hide the ToolWindow caption to make it look like a panel and you can cancel the drag operations if not needed. 

I hope that you find this information useful.
