Tooltips在Spreeadsheetcontrol中的使用

Tooltips在Spreeadsheetcontrol中显示出来，代码如下：
这样可以有比较好的提示效果了，比通过批注、有效性做提示要更流畅一些。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using DevExpress.Spreadsheet;
using DevExpress.Utils;
namespace SpreadsheetTooltip
{
public partial class Form1 : DevExpress.XtraEditors.XtraForm
{
public Form1()
{
InitializeComponent();
spreadsheetControl1.ToolTipController = toolTipController1;
toolTipController1.GetActiveObjectInfo += ToolTipController1_GetActiveObjectInfo;
spreadsheetControl1.LoadDocument("template.xlsx");
}
private void ToolTipController1_GetActiveObjectInfo(object sender, DevExpress.Utils.ToolTipControllerGetActiveObjectInfoEventArgs e)
{
if (e.SelectedControl != spreadsheetControl1)
return;
Cell cell = spreadsheetControl1.GetCellFromPoint(new PointF(e.ControlMousePosition.X, e.ControlMousePosition.Y));
if (cell == null) return;
if (cell.IsMerged)
cell = cell.GetMergedRanges().First()[0];
if(!cell.Value.IsEmpty)
{
ToolTipControlInfo info = new ToolTipControlInfo(cell, string.Empty);

item.Font = new Font("Arial", 10);
item.ImageOptions.SvgImage = svgImageCollection1[cell.Value.Type.ToString().ToLower()];
item.Text = PrepareCellTooltip(cell);
sToolTip.Items.Add(item);
info.SuperTip = sToolTip;
e.Info = info;
}
}
private string PrepareCellTooltip(Cell cell)
{
string cellReference = cell.GetReferenceA1();
string cellDataType = cell.Value.Type.ToString();
string cellDisplayText = cell.DisplayText;
return String.Format("Cell reference: {0}\r\nData type: {1}\r\nValue: {2}", cellReference, cellDataType, cellDisplayText);
}
}
