DataGridViewRowHeightInfoPushedEventHandler

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the RowHeightInfoPushed 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 RowHeightInfoPushed event.

private void DataGridView1_RowHeightInfoPushed(Object sender, DataGridViewRowHeightInfoPushedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Height", e.Height );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "MinimumHeight", e.MinimumHeight );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Handled", e.Handled );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "RowHeightInfoPushed Event" );
}

Private Sub DataGridView1_RowHeightInfoPushed(sender as Object, e as DataGridViewRowHeightInfoPushedEventArgs) _ 
     Handles DataGridView1.RowHeightInfoPushed

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Height", e.Height)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "MinimumHeight", e.MinimumHeight)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Handled", e.Handled)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"RowHeightInfoPushed Event")

End Sub

Remarks

This event is raised when the VirtualMode property is set to true or the DataSource property is set to a value other than null. This event is used to track and store row height information so that it can be restored after a sorting operation. To restore height information, handle the RowHeightInfoNeeded event. Note that this event occurs only when the user changes the height of a row. If you change the height of a row programmatically, you must store the new height information at the same time.
