  Required Field Validator Help

  Dec 05, 2012 10:02 PM|LINK

  I have an aspx page where one of the Textboxes has a RequiredFieldValidator like so:

  <td>
                  <asp:Label ID="visNamelbl" runat="server" Text="Visitor Name:" Font-Size="Small" Font-Bold="true" ForeColor="Black"></asp:Label>
              </td>
              <td onkeypress="dumpEnter">
                  <asp:TextBox ID="visName" runat="server"></asp:TextBox>
              </td>
              <td>
                  <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="visName" ValidationGroup="SubmitGroup"
                      ErrorMessage="Visitor Name is required" ForeColor="DarkRed" Font-Bold="true" ></asp:RequiredFieldValidator>
              </td> 

  Here is my problem. I take the values entered in the Textbox and hold them in a session variable in case the user has multple visitors to enter. When I move the textbox value to the session how do I omit the RequiredField Validator?

   protected void NameList()
          { 
              List<string> visitors = (Session["Visitors"] == null ? new List<string>() : (List<string>)Session["Visitors"]);
   
              if (!string.IsNullOrEmpty(visName.Text))
              {
                  visitors.Add(visName.Text);
              }
   
              Session["Visitors"] = visitors;
   
              ListBox1.DataSource = visitors;
              ListBox1.DataBind();            
          } // end method

   // Method to add users to ListBox
          protected void btnSpawnList_Click(object sender, EventArgs e)
          {
              // Call mehtod
              NameList();
                          
              if (IsPostBack)
              {
                  visName.Text = string.Empty;
              } // End PostBack            
          } // End Method

  I want it there on inital load, but after 1 name has been entered it should not be required anymore. Any Ideas?

  Remove reequiredvalidator and use label, create your own serverside validation.

  LabelMessage.text="Visitor Name is required"
