在编辑模式下验证gridview内的文本框? [英] Validate textbox inside gridview at edit mode ?

问题描述

大家好，

我正在尝试通过javascript在gridview内的编辑模式下验证文本框，但没有找到方法.

这是我的代码:

Hi all ,

I am trying to validate a textbox at edit mode inside a gridview from javascript but did not find a way.

Here is my code:

<asp:GridView ID="GridView1" runat="server" Width="100%" AutoGenerateColumns="False"

            DataKeyNames="News_Id" DataSourceID="ods_news">
            <Columns>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:LinkButton ID="LinkButton1" runat="server" CommandName="edit" ValidationGroup="ss">edit</asp:LinkButton>
                    </ItemTemplate>
                    <EditItemTemplate>
                        <asp:LinkButton ID="LinkButton2" runat="server" ValidationGroup="ss" CommandName="update" OnClientClick="GetCompanyText();">update</asp:LinkButton>
                        <asp:LinkButton ID="LinkButton3" runat="server" CommandName="cancel">cancel</asp:LinkButton>
                    </EditItemTemplate>
                </asp:TemplateField>
                <asp:BoundField DataField="News_Id" HeaderText="News_Id" InsertVisible="False" ReadOnly="True"

                    SortExpression="News_Id" />
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:Label ID="Label1" runat="server" Text='<%# Bind("News_Title") %>'></asp:Label>
                    </ItemTemplate>
                    <EditItemTemplate>
                        <asp:TextBox ID="TextBox1" runat="server" ValidationGroup="ss" Text='<%# Bind("News_Title") %>'></asp:TextBox>
                        <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="Required" ControlToValidate="TextBox1" ValidationGroup="ss"></asp:RequiredFieldValidator>
                    </EditItemTemplate>
                </asp:TemplateField>
                <%--  <asp:BoundField DataField="News_Title" HeaderText="News_Title" SortExpression="News_Title" />--%>
                <asp:BoundField DataField="News_Brief" HeaderText="News_Brief" SortExpression="News_Brief" />
                <asp:BoundField DataField="News_Text" HeaderText="News_Text" SortExpression="News_Text" />
                <asp:BoundField DataField="News_Date" HeaderText="News_Date" SortExpression="News_Date" />
                <asp:BoundField DataField="News_Image" HeaderText="News_Image" SortExpression="News_Image" />
                <asp:CheckBoxField DataField="News_IsActive" HeaderText="News_IsActive" SortExpression="News_IsActive" />
                <asp:BoundField DataField="News_Sort" HeaderText="News_Sort" SortExpression="News_Sort" />
            </Columns>
        </asp:GridView>

因此，在linkbutton1 click事件上，我想调用一个获取文本框值的javascript函数.

So on the linkbutton1 click event i want to call a javascript function that gets the value of textbox .
