DevExpress和C＃：選擇值后驗證RepositoryItemLookUpEdit單元格

Question

我有一個GridView其中我有此列：

bandedGridColumn.ColumnEdit = InitEdit_Material();

這是InitEdit_Material方法：

public static RepositoryItemLookUpEdit InitEdit_Material()
{
    RepositoryItemLookUpEdit riMaterial = new RepositoryItemLookUpEdit();

    riMaterial.Columns.Add(new LookUpColumnInfo("ID", "ID"));
    riMaterial.Columns.Add(new LookUpColumnInfo("CustomsMaterial.Name", "Name"));

    riMaterial.DataSource = Service.GetAll(svc.EntityTypeToGet.Material).Data.All_Material;

    riMaterial.DisplayMember = "MaterialFullname";
    riMaterial.ValueMember = "ID";

    riMaterial.AutoSearchColumnIndex = 1;
    riMaterial.BestFitMode = BestFitMode.BestFitResizePopup;
    riMaterial.NullText = "";


    return riMaterial;
}

看起來是這樣的：

每當用戶在此單元格中選擇一個新值時，我都想執行一些操作（根據當前單元格的值設置其他單元格的值），但是問題是我知道所有可能的事件僅在該單元格失去焦點后才會觸發，我嘗試過：

private void vwVD_ValidatingEditor(object sender, BaseContainerValidateEditorEventArgs e)
{
    if (vwVD.FocusedColumn.Name == "colMaterialID") 
        MessageBox.Show("only show when focus lost");
    return;
}

private void vwVD_CellValueChanged(object sender, CellValueChangedEventArgs e)
{
    if (e.Column.Name != "colMaterialID") return;

    MessageBox.Show("only show when focus lost");
}

Answer 1

您可以嘗試使用GridView.CellValueChanging事件：

private void vwVD_CellValueChanging(object sender, CellValueChangedEventArgs e)
{
    if (vwVD.FocusedColumn.Name == "colMaterialID")
    {
        //Perform some actions. Use e.Value.
    }
}
