自定义cellType的问题！！！

收藏

问题说明：当按下面代码写好程序后，第一次点击单元格时，能够出现带...的小按钮，第二次无论点击任何单元格，都不再显示。请教解决办法。谢谢。

1.创建一winform应用程序，在form1中放入spread控件
2.加入下列代码：

复制代码

其中的FPTextCellType 为自定义类，代码如下

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using FarPoint.Win.Spread;
using FarPoint.Win.Spread.CellType;
using System.Drawing.Printing;
using FarPoint.Win;
using System.Drawing.Drawing2D;
using System.Globalization;
using FarPoint.Win.Spread.Model;
using Microsoft.Win32;
namespace Test
{
public class FPTextCellType : TextCellType
{
public override Control GetEditorControl(FarPoint.Win.Spread.Appearance appearance, float zoomFactor)
{
appearance.BackColor = Color.Red;
Control c = base.GetEditorControl(appearance, zoomFactor);
((GeneralEditor)c).ButtonStyle = ButtonStyle.PopUp;
return c;
}
protected override void FireEditorValueChanged(EventArgs e)
{
base.FireEditorValueChanged(e);
}
}
}

你好，可以在 EditModeOn 事件中设置 editor 去实现该功能，参考代码：

private void fpSpread1_EditModeOn(object sender, EventArgs e)
{
FarPoint.Win.Spread.CellType.GeneralEditor c = this.fpSpread1.EditingControl as FarPoint.Win.Spread.CellType.GeneralEditor;
c.ButtonStyle = ButtonStyle.PopUp;
c.BackColor = Color.Red;
}
