GcMultiRow.EditingControlShowingイベントでイベントハンドラをe.Controlの任意のイベントに関連付けます。

次のサンプルコードは、GcTextBox.TextChangingイベントと同じ処理をGcTextBoxEditingControl.TextChangingイベントで実装します。（GcTextBoxEditingControlクラスはGcTextBoxクラスの派生クラスです）

[Visual Basic]

Imports InputManCell = GrapeCity.Win.MultiRow.InputMan

Private Sub GcMultiRow1_EditingControlShowing(ByVal sender As System.Object, ByVal e As GrapeCity.Win.MultiRow.EditingControlShowingEventArgs) Handles GcMultiRow1.EditingControlShowing
　　If TypeOf e.Control Is InputManCell.GcTextBoxEditingControl Then
　　　　Dim gcTextBox As InputManCell.GcTextBoxEditingControl = TryCast(e.Control, InputManCell.GcTextBoxEditingControl)
　　　　RemoveHandler gcTextBox.TextChanging, AddressOf GcTextBox_TextChanging
　　　　AddHandler gcTextBox.TextChanging, AddressOf GcTextBox_TextChanging
　　End If
End Sub

Private Sub GcTextBox_TextChanging(ByVal sender As System.Object, ByVal e As GrapeCity.Win.Editors.TextChangingEventArgs)
　　Console.WriteLine(e.Result)
End Sub

[C#]

using InputManCell = GrapeCity.Win.MultiRow.InputMan;

private void gcMultiRow1_EditingControlShowing(object sender, GrapeCity.Win.MultiRow.EditingControlShowingEventArgs e)
{
　　if (e.Control is InputManCell.GcTextBoxEditingControl)
　　{
　　　　InputManCell.GcTextBoxEditingControl gcTextBox = e.Control as InputManCell.GcTextBoxEditingControl;
　　　　gcTextBox.TextChanging -= new GrapeCity.Win.Editors.TextChangingEventHandler(gcTextBox_TextChanging);
　　　　gcTextBox.TextChanging += new GrapeCity.Win.Editors.TextChangingEventHandler(gcTextBox_TextChanging);
　　}
}

private void gcTextBox_TextChanging(object sender, GrapeCity.Win.Editors.TextChangingEventArgs e)
{
　　Console.WriteLine(e.Result);
}
