五、初学.NET—Gridview自动编号和鼠标停留行加背景
前端:在GridView中添加一普通绑定列
<asp:BoundField HeaderText="序号" ItemStyle-Width="60px">
<ItemStyle Width="60px"></ItemStyle>
</asp:BoundField>
后台:通过RowDataBound事件处理代码后台绑定,鼠标停留一行加背景
protected void gv_ReviewOption_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{ int id = e.Row.RowIndex + 1;
e.Row.Cells[1].Text = id.ToString();
e.Row.Attributes.Add("onmouseover", "currentcolor=this.style.backgroundColor;this.style.backgroundColor='lightblue'");//鼠标移上去时
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=currentcolor;");//鼠标移开时
}
}
