Asp.net Gridview：保留SelectedRow的样式

我通过样式表更改行“普通”、“备用”和“选定”的样式。此外，我还使用gv_Alternativen_RowDataBound实现了onmouseover、onmouseout和class

但是，当我在所选行中进行鼠标悬停时，错误的onmouseout被放置在那里：

    Protected Sub gv_Alternativen_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gv_Alternativen.RowDataBound
    If e.Row.RowType = DataControlRowType.DataRow Then
        Select Case e.Row.RowState
            Case Is <> DataControlRowState.Selected
                'odd even
                If e.Row.RowState = DataControlRowState.Normal And e.Row.RowState <> DataControlRowState.Selected Then
                    e.Row.Attributes.Clear()
                    e.Row.Attributes.Add("onmouseout", "this.className='PopupAngeboteRow'")
                    e.Row.Attributes.Add("onmouseover", "this.className='PopupAngeboteRowHover'")
                    e.Row.Attributes.Add("class", "PopupAngeboteRow")
                ElseIf e.Row.RowState = DataControlRowState.Alternate And e.Row.RowState <> DataControlRowState.Selected Then
                    e.Row.Attributes.Clear()
                    e.Row.Attributes.Add("onmouseout", "this.className='PopupAngeboteAlternatingRow'")
                    e.Row.Attributes.Add("onmouseover", "this.className='PopupAngeboteRowHover'")
                    e.Row.Attributes.Add("class", "PopupAngeboteAlternatingRow")
                End If
            Case Is = DataControlRowState.Selected
                e.Row.Attributes.Clear()
                e.Row.Attributes.Add("onmouseover", "this.className='PopupAngeboteRowSelected'")
                e.Row.Attributes.Add("onmouseout", "this.className='PopupAngeboteRowSelected'")
                e.Row.Attributes.Add("class", "PopupAngeboteRowSelected")
        End Select
    End If
End Sub

Protected Sub gv_Alternativen_RowDataBound（ByVal sender作为对象，ByVal e作为System.Web.UI.WebControls.GridViewRowEventArgs）处理gv_Alternativen.RowDataBound
如果e.Row.RowType=DataControlRowType.DataRow，则
选择Case e.Row.RowState
大小写为DataControlRowState。已选定
“奇偶
如果选择了e.Row.RowState=DataControlRowState.Normal和e.Row.RowState DataControlRowState
e、 Row.Attributes.Clear（）
e、 添加（“onmouseout”，“this.className='PopupAngeboteRow'”）
e、 Row.Attributes.Add（“onmouseover”，“this.className='popupangeboterowhere'”）
e、 添加（“类”，“PopuPangeBoterRow”）
ElseIf e.Row.RowState=DataControlRowState.Alternate和e.Row.RowState DataControlRowState。然后选择
e、 Row.Attributes.Clear（）
e、 添加（“onmouseout”，“this.className='PopupAngeboteAlternatingRow'”）
e、 Row.Attributes.Add（“onmouseover”，“this.className='popupangeboterowhere'”）
e、 添加（“类”，“PopupAngeboteAlternatingRow”）
如果结束
案例为=DataControlRowState。已选定
e、 Row.Attributes.Clear（）
e、 添加（“onmouseover”，“this.className='PopuPangeBoterRowselected'”）
e、 添加（“onmouseout”，“this.className='PopuPangeBoterRowselected'”）
e、 添加（“类”，“PopuPangeBoterRowselected”）
结束选择
如果结束
端接头

有什么想法吗

thx提前很多时间，问候…

你能解释一下为什么这样做而不是仅仅给出答案吗。

protected void gvHolds_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if ((e.Row.RowIndex % 2) == 0)
            {
                if (e.Row.RowIndex == gvHolds.SelectedIndex) 
                {
                    e.Row.Attributes["onmouseout"] = "this.className = 'SelectedRow';";
                    e.Row.Attributes["onmouseover"] = "this.className = 'MouseOverRow';";
                }
                else
                {
                    e.Row.Attributes["onmouseout"] = "this.className = 'oddRow';";
                    e.Row.Attributes["onmouseover"] = "this.className = 'MouseOverRow';";
                }
            }
            else
            {
                if (e.Row.RowIndex == gvHolds.SelectedIndex) 
                {
                    e.Row.Attributes["onmouseout"] = "this.className = 'SelectedRow';";
                    e.Row.Attributes["onmouseover"] = "this.className = 'MouseOverRow';";
                }
                else
                {
                    e.Row.Attributes["onmouseout"] = "this.className = 'evenRow';";
                    e.Row.Attributes["onmouseover"] = "this.className = 'MouseOverRow';";
                }
            }

            e.Row.Attributes["onclick"] = ClientScript.GetPostBackEventReference(this.gvHolds, "Select$" + e.Row.RowIndex);
        }
    }
