鼠标指向 gridview 某行，某行颜色加亮

在RowDataBound事件里写

Dim i As Int32        For i = 0 To GridView1.Rows.Count
            If e.Row.RowType = DataControlRowType.DataRow Then
                e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#00A9FF'")
                e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c")
            End If
        Next

当然，也可更简单些：

If e.Row.RowType = DataControlRowType.DataRow Then            e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'")
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'")
        End If
