DataGrid鼠标到达的行和列显示不同的颜色

本例的实现原理是在向DataGrid绑定数据的同时为相应的单元格添加onmouseover和onmouseout事件。主要代码如下
1



/**//// <summary>
2

/// 增加颜色属性
3

/// </summary>
4

/// <param name="sender"></param>
5

/// <param name="e"></param>
6

private void DataGrid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
7





{
8

if(e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
9





{
10

e.Item.Attributes.Add("onmouseover","this.oldcolor=this.style.backgroundColor;this.style.backgroundColor='#C8F7FF'");
11

e.Item.Attributes.Add("onmouseout", "this.style.backgroundColor=this.oldcolor");
12

for (int i=0;i<DataGrid1.Columns.Count;i++)
13





{
14

e.Item.Cells[i].Attributes.Add("onmouseover","this.oldcolor=this.style.backgroundColor;this.style.backgroundColor='#99ccff'");
15

e.Item.Cells[i].Attributes.Add("onmouseout", "this.style.backgroundColor=this.oldcolor");
16

}
17

}
18

}
