  RequiredField Validation in visual studio 2013

  Jun 25, 2015 02:34 PM|EasyHero|LINK

  I used a required field validation control to validate a textbox using the following lines of codes

  <asp:Label ID="Label25" runat="server" Text="School"></asp:Label>
  <asp:TextBox ID="schl" runat="server" Width ="320px"></asp:TextBox>
  <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="*" ControlToValidate="schl" Text="*"></asp:RequiredFieldValidator>
  
  <asp:Button ID="addschool" runat="server" Text="Add" CssClass="button" BackColor="#333333" BorderColor="Silver" OnClick="addschool_Click" BorderWidth="2px" Width="150px" />

  this is the back code of the button

  protected void addschool_Click(object sender, EventArgs e)
          {
              try
              {
                  if (Page.IsValid)
                  {
                      error.Text = "";
                      MySqlConnection conn = new MySqlConnection(connection);
                      MySqlCommand addschool = new MySqlCommand("insert into pla20132014.schools (Departments, Schools) values(@dept, @schl)", conn);
                      MySqlDataReader read;
                      conn.Open();
                      addschool.Parameters.Add("@dept", MySqlDbType.VarChar).Value = dept.Text;
                      addschool.Parameters.Add("@schl", MySqlDbType.VarChar).Value = schl.Text;
                      read = addschool.ExecuteReader();
                      read.Close();
                      conn.Close();
                      error.ForeColor = Color.Green;
                      error.Text = "Upload Successful";
  
                  }
              }
              catch(MySqlException myex)
              {
                  error.Text = myex.Message;
              }
              catch(Exception ex)
              {
                  error.Text = "/n " + ex.Message;
              }
          }

  but i receive the following error in stack trace
  
  

  [InvalidOperationException: WebForms UnobtrusiveValidationMode requires a ScriptResourceMapping for 'jquery'. Please add a ScriptResourceMapping named jquery(case-sensitive).]
     System.Web.UI.ClientScriptManager.EnsureJqueryRegistered() +2287754

     System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +974

  i really don't know what is wrong because i use same code in visual studio 2010 and it works perfectly. Thanks for your assistance

  Do you have jquery.validate.js installed and reference in your page?

  You need to add it to BundleConfig.cs in App_Start folder, please follow the way how other packages are added there.

  Well, to get the idea how the files are created and organized in App_Start folder do the following steps:

  • Create a new MVC Web Site project (Don't select the Empty template)
  • When the project has been created, open the solution explorer and find App_Start folder and you will see there are 5 file (.cs) files there. 
  • One of them is BundleConfig.cs, open file and see what is there, bundled packages for js, css and other files from the folders of your project.
  • The bundle names are being called in your .Layout.cshtml files so that all the pages are rendered with the scripts added as bundles.

  Hope this will help.
