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
}
/// <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
}
