  Validator to test if one of 2 text boxes have a value

  Aug 02, 2012 06:11 PM|LINK

  Hello,

  I am writing an asp.net application for a benchmark and I wanted to know if there is a validator that will test if 2 text boxes have a value and if both text boxes do not a have value the validator will fire.

  Thanks,

  protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args)
          {
              if (txtsomething.text == null && txtRtsomething.Text == null)
              {
                  args.IsValid = true;
              }
              else
              {
                  args.IsValid = false;
              }
          }

  You can use custom validator.. or use JS script to validate. Something like this..

  <asp:Button ID="Button1" runat="server" Text="Submit" OnClientClick="return ValidateTextBox();" />
  
  
  <script type="text/javascript" language="javascript">
      
       function ValidateTextBox()
       {
         var txt1 = document.getElementById('<%= TextBox1.ClientID %>');
         var txt2 = document.getElementById('<%= TextBox2.ClientID %>');
              if( txt1.value == "" || txt2.value == "")
              {
                 alert('Enter info for atleast one!');
                 return false;
  
              }
              else
              {return true;}
       }
  
      </script>

  Just change textbox id's in following code..

  var txt1 = document.getElementById('<%= TextBox1.ClientID %>');
         var txt2 = document.getElementById('<%= TextBox2.ClientID %>');

  Thank You,

  Do you know why my server side validator is not working?

  Thanks in advance.

  protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args)
          {
              if (txtsomething.text == null && txtRtsomething.Text == null)
              {
                  args.IsValid = true;
              }
              else
              {
                  args.IsValid = false;
              }
          }
