验证在GridView控件在EditItemTemplate中工作不适合文本框 [英] Validation in GridView not working for TextBox in EditItemTemplate

问题描述

我想添加一个 RegularEx pressionValidator 中的 EditItemTemplate中在一个文本框 GridView控件控制。

当用户点击更新，如果输入错误，验证工作（错误信息可见）。但是，在 OnRowUpdating 方法，我有 Page.IsValid ==真。为什么会出现这种情况？

ASPX code：

 ＆LT; ASP：GridView控件ID =dgvsaldoPV=服务器可见=假的AutoGenerateColumns =FALSE
        ShowFooter =真AllowSorting =真OnSorting =TaskGridView_SortingSaldoPVOnRowEditing =gv1_RowEditing
        OnRowUpdating =gv1_RowUpdatingonRowCancelingEdit =gv1_RowCancelingEdit的DataKeyNames =ID_CASSA＆GT;

解决方案

尝试调用

  Page.Validate（）;
 

你的 GridView.RowUpdating 事件的开始。这将迫使所有的服务器端验证器的检查。我希望，这已被称为由点，但它听起来像并非如此。

如果你的 GridView控件里面的的UpdatePanel 做一个局部回传，或者是造成回发火灾控制未设置为导致验证（这是 .CausesValidation 属性设置为false），那么我可以想像 Page.IsValid 属性没有被正确填充呢。

I am trying to add a RegularExpressionValidator for a textbox in an EditItemTemplate in a GridView control.

When a user clicks on "update", if the input is wrong, the validator work (error message is visible). But, in the OnRowUpdating method, I have Page.IsValid==true. Why is this happening?

ASPX code:

<asp:GridView ID="dgvsaldoPV" runat="server" Visible="False" AutoGenerateColumns="False" 
        ShowFooter="True" AllowSorting="True" OnSorting="TaskGridView_SortingSaldoPV" OnRowEditing="gv1_RowEditing" 
        OnRowUpdating="gv1_RowUpdating" onRowCancelingEdit="gv1_RowCancelingEdit" DataKeyNames="ID_CASSA">
        <AlternatingRowStyle BackColor="#FFFFCC" />
        <Columns>

            <asp:TemplateField HeaderText="Saldo" InsertVisible="False" SortExpression="SALDO" >
                <EditItemTemplate >
                    <asp:TextBox ID="txtsaldo" runat="server" validationgroup="saldo" Text='<%# Bind("SALDO") %>'></asp:TextBox>
                    <asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ControlToValidate="txtsaldo"
                ErrorMessage="Inserisci valori numerici, usare ',' per i decimali" ValidationExpression="^\d*\,?\d+$" validationgroup="saldo"
                    ForeColor="Red" ></asp:RegularExpressionValidator>
                </EditItemTemplate>
                <ItemTemplate >
                    <asp:Label ID="Label1" runat="server" Text='<%# Bind("SALDO") %>'></asp:Label>
                </ItemTemplate>
                <ItemStyle CssClass="style11"    />
            </asp:TemplateField>

            <asp:CommandField ShowEditButton="True" ShowHeader="false" HeaderStyle-CssClass="headerstyle1"/>
        </Columns>
        <FooterStyle BackColor="#CC0000" ForeColor="White" />
        <HeaderStyle CssClass="headerstyle" />
        <RowStyle HorizontalAlign="Center" VerticalAlign="Middle"/>

    </asp:GridView>

解决方案

Try calling

Page.Validate();

at the beginning of your GridView.RowUpdating event. This will force a check of all the server-side validators. I would expect that this had already been called by that point, but it sounds like that's not the case.

If your GridView is inside an UpdatePanel doing a partial PostBack, or the control that's causing the PostBack to fire is not set to cause validation (it's .CausesValidation property is set to false), then I could imagine the Page.IsValid property not being properly populated yet.
