Question

Hi

  How to display Validations on Client-Side/Server Side using Sweet Alert

<div class="input-group mb-4">
                                            <span class="input-group-text"><i class="fas fa-user-tie"></i></span>
                                            <asp:TextBox ID="txtUserId" runat="server" required="true" CssClass="form-control" placeholder="Login ID"></asp:TextBox>
                                        </div>
                                        <div class="input-group mb-4">
                                            <span class="input-group-text"><i class="fas fa-key"></i></span>
                                            <asp:TextBox ID="txtPassword" runat="server" required="true" TextMode="Password" CssClass="form-control" placeholder="Your Password"></asp:TextBox>
                                        </div>
