DataGridView.Scroll Event

  • Reference

Definition

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

Occurs when the user scrolls through the control contents.

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

Event Type

ScrollEventHandler

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the Scroll 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 DataGridView named DataGridView1. Then ensure that the event handler is associated with the Scroll event.

private void DataGridView1_Scroll(Object sender, ScrollEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "ScrollOrientation", e.ScrollOrientation );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Type", e.Type );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "NewValue", e.NewValue );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "OldValue", e.OldValue );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "Scroll Event" );
}

Private Sub DataGridView1_Scroll(sender as Object, e as ScrollEventArgs) _ 
     Handles DataGridView1.Scroll

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "ScrollOrientation", e.ScrollOrientation)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Type", e.Type)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "NewValue", e.NewValue)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "OldValue", e.OldValue)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"Scroll Event")

End Sub
