Splitter.SplitterMoved Event

  • Reference

Definition

Namespace:
System.Windows.Forms
Assembly:
System.Windows.Forms.dll

Occurs when the splitter control is moved. SplitterMoved has been replaced by SplitterMoved and is provided only for compatibility with previous versions.

public:
 event System::Windows::Forms::SplitterEventHandler ^ SplitterMoved;
public event System.Windows.Forms.SplitterEventHandler SplitterMoved;
public event System.Windows.Forms.SplitterEventHandler? SplitterMoved;
member this.SplitterMoved : System.Windows.Forms.SplitterEventHandler 
Public Custom Event SplitterMoved As SplitterEventHandler

Event Type

SplitterEventHandler

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the SplitterMoved event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type Splitter named Splitter1. Then ensure that the event handler is associated with the SplitterMoved event.

private void Splitter1_SplitterMoved(Object sender, SplitterEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "X", e.X );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Y", e.Y );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "SplitX", e.SplitX );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "SplitY", e.SplitY );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "SplitterMoved Event" );
}

Private Sub Splitter1_SplitterMoved(sender as Object, e as SplitterEventArgs) _ 
     Handles Splitter1.SplitterMoved

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "X", e.X)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Y", e.Y)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "SplitX", e.SplitX)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "SplitY", e.SplitY)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"SplitterMoved Event")

End Sub

Remarks

You can create an event handler for the SplitterMoved event to perform resize validation in your application. For example, if a Splitter control is docked to the edges of a TreeView control and a ListView control, you can write code in the SplitterMoved event to determine if the minimum and/or maximum size for the TreeView and ListView controls has been exceeded and resize the controls to their minimum or maximum size.
