Question

GridView 怎么设置选中一项的时候就马上改变背景颜色

Answer 1

1、首先在.aspx页面块中添加javascript
<script type="text/javascript">
var prevselitem=null;
function selectx(row)
{
if(prevselitem!=null)
{
prevselitem.style.backgroundColor='#ffffff';
}
row.style.backgroundColor='PeachPuff';
prevselitem=row;
}
</script>

2、然后修改GridView,添加事件OnRowDataBound

protectedvoid GridView1_RowDataBound(object sender,GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
// e.Row.Attributes.Add("onmouseover", "if(this!=prevselitem){this.style.backgroundColor='#Efefef'}");//当鼠标停留时更改背景色
// e.Row.Attributes.Add("onmouseout", "if(this!=prevselitem){this.style.backgroundColor='#ffffff'}");//当鼠标移开时还原背景色
e.Row.Attributes.Add("onclick", e.Row.ClientID.ToString() + ".checked=true;selectx(this)");//点击行变色

//e.Row.Attributes["style"] = "Cursor:hand"; //设置悬浮鼠标指针形状为"小手"
// GridView1.HeaderRow.Cells[10].Visible = false;
// e.Row.Cells[10].Visible = false;//隐藏选择按钮
//String evt = Page.ClientScript.GetPostBackClientHyperlink(sender as System.Web.UI.WebControls.GridView, "Select$" + e.Row.RowIndex.ToString());
// e.Row.Attributes.Add("onclick", evt);//执行选择行GridView1_SelectedIndexChanged事件
}
