更新時(shí)間：2012-01-12 | 發(fā)布人：本站 | 點(diǎn)擊率：553 次

閱讀此文請(qǐng)先查看網(wǎng)頁(yè)教學(xué)網(wǎng)的：ASP.NET入門教程:Validation服務(wù)器控件，簡(jiǎn)單講述了Web服務(wù)器控件的使用方法。

定義和用法

ValidationSummary 控件用于在網(wǎng)頁(yè)、消息框或在這兩者中內(nèi)聯(lián)顯示所有驗(yàn)證錯(cuò)誤的摘要。顯示 Web 頁(yè)上所有驗(yàn)證錯(cuò)誤的列表。

在該控件中顯示的錯(cuò)誤消息是由每個(gè)驗(yàn)證控件的 ErrorMessage 屬性規(guī)定的。如果未設(shè)置驗(yàn)證控件的 ErrorMessage 屬性，就不會(huì)為那個(gè)驗(yàn)證控件顯示錯(cuò)誤消息。

實(shí)例

<asp:ValidationSummary
    AccessKey="string"
    BackColor="color name|#dddddd"
    BorderColor="color name|#dddddd"
    BorderStyle="NotSet|None|Dotted|Dashed|Solid|Double|Groove|Ridge|
        Inset|Outset"
    BorderWidth="size"
    CssClass="string"
    DisplayMode="List|BulletList|SingleParagraph"
    EnableClientScript="True|False"
    Enabled="True|False"
    EnableTheming="True|False"
    EnableViewState="True|False"
    Font-Bold="True|False"
    Font-Italic="True|False"
    Font-Names="string"
    Font-Overline="True|False"
    Font-Size="string|Smaller|Larger|XX-Small|X-Small|Small|Medium|
        Large|X-Large|XX-Large"
    Font-Strikeout="True|False"
    Font-Underline="True|False"
    ForeColor="color name|#dddddd"
    HeaderText="string"
    Height="size"
    ID="string"
    OnDataBinding="DataBinding event handler"
    OnDisposed="Disposed event handler"
    OnInit="Init event handler"
    OnLoad="Load event handler"
    OnPreRender="PreRender event handler"
    OnUnload="Unload event handler"
    runat="server"
    ShowMessageBox="True|False"
    ShowSummary="True|False"
    SkinID="string"
    Style="string"
    TabIndex="integer"
    ToolTip="string"
    ValidationGroup="string"
    Visible="True|False"
    Width="size"
/>

備注：ValidationSummary 控件允許在單個(gè)位置概述網(wǎng)頁(yè)上所有驗(yàn)證控件的錯(cuò)誤信息�；� DisplayMode 屬性的值，該摘要可顯示為列表、項(xiàng)目符號(hào)列表或單個(gè)段落。ValidationSummary 控件中為頁(yè)面上每個(gè)驗(yàn)證控件顯示的錯(cuò)誤信息，是由每個(gè)驗(yàn)證控件的 ErrorMessage 屬性指定的。如果沒(méi)有設(shè)置驗(yàn)證控件的 ErrorMessage 屬性，將不會(huì)在 ValidationSummary 控件中為該驗(yàn)證控件顯示錯(cuò)誤信息。通過(guò)設(shè)置 HeaderText 屬性，還可以在 ValidationSummary 控件的標(biāo)題部分指定一個(gè)自定義標(biāo)題。

通過(guò)設(shè)置 ShowSummary 屬性，可以控制 ValidationSummary 控件是顯示還是隱藏。還可通過(guò)將 ShowMessageBox 屬性設(shè)置為 true，在消息框中顯示摘要。

示例

下面的代碼示例演示如何使用 ValidationSummary 控件來(lái)概述頁(yè)上的未通過(guò)驗(yàn)證的輸入控件。
