回避方法

検索ダイアログのインスタンスを取得して既存のダイアログの動作を変更する方法が考えられます。

製品サンプル（GcSpreadGridデモ ＞ セル ＞ 検索ダイアログ）の場合、uCellSearchDialog.xaml.csを以下のように実装することで回避が可能となります。

■サンプルコード（C#）

using GrapeCity.Windows.SpreadGrid;
using System;
using System.Runtime.CompilerServices;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;

namespace GrapeCity.WPF.Spread.Sample.GcSpreadGrid

    /// 
    public partial class uCellSearchDialog : UserControl
    {
        public uCellSearchDialog()
        {
            InitializeComponent();

            // データを連結
            gcSpreadGrid1.ColumnCount = 7;

            gcSpreadGrid1.Columns[0].DataField = new PropertyDataField() { Property = "ProductCode" };
            gcSpreadGrid1.Columns[1].DataField = new PropertyDataField() { Property = "ProductName" };
            gcSpreadGrid1.Columns[2].DataField = new PropertyDataField() { Property = "StockDate" };

            gcSpreadGrid1.Columns[5].DataField = new PropertyDataField() { Property = "Term" };
            gcSpreadGrid1.Columns[6].DataField = new PropertyDataField() { Property = "Section" };

            // 列幅を設定
            gcSpreadGrid1.Columns[0].Width = 90;
