我在网格视图控件中有一个文本框,我使用必需的字段验证器来验证文本框
<asp:TemplateField HeaderText="Relationship" ItemStyle-Width="15%">
<ItemTemplate>
<asp:TextBox ID="txtRelationShip" runat="server" Text='<%# Eval("RelationShip") %>' Visible="false" autocomplete="off"></asp:TextBox>
<asp:RequiredFieldValidator ID="rfvRelationShip" runat="server" ControlToValidate="txtRelationShip" ForeColor="Red" ClientIDMode="AutoID"
ErrorMessage="Please enter relationship" ValidationGroup="vgUpdateRelationShip" Display="Dynamic"></asp:RequiredFieldValidator>
<asp:LinkButton ID="btnRelationShipUpdate" runat="server" ValidationGroup="vgUpdateRelationShip"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
我的网格视图中有很多行,当我编辑和更新文本框值时,如果单个文本框为空,则在所有文本框中显示错误。如何解决这个问题,我想如果单个文本框为空,则仅在单个文本框中显示错误
你必须确保ValidationGroup
每行都是唯一的,比如ValidationGroup='<%# "ValidationGroup_" + Container.DataItemIndex %>'
<asp:TemplateField>
<ItemTemplate>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="RequiredFieldValidator"
ControlToValidate="TextBox1" ValidationGroup='<%# "ValidationGroup_" + Container.DataItemIndex %>'></asp:RequiredFieldValidator>
<asp:LinkButton ID="LinkButton1" runat="server" ValidationGroup='<%# "ValidationGroup_" + Container.DataItemIndex %>'>Update</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
