I have 6 fields in my database as bit fields.

I want to insure the user can't save the forn without selecting at least one of the six.

Anyone know how to do this ?

To ensure that at least one of the six bit fields is selected before allowing the user to save the form in ASPRunner.NET, you can use client-side validation. Here's a general approach to achieve this:

  1. Identify the Fields: Make sure you know the IDs or names of the bit fields in your form. For example, let's say they are named Field1, Field2, Field3, Field4, Field5, and Field6.


  2. Add JavaScript Validation: You can add a JavaScript function to validate the fields before the form is submitted. This function should check if at least one of the fields is checked (or selected).


  3. Attach the Validation to the Form Submission: You will need to call the validation function when the form is submitted.



Here’s a sample code snippet you can use in your ASPRunner.NET application:

<script type="text/javascript">
function validateForm() {
 var fields = [
 document.getElementById("Field1").checked,
 document.getElementById("Field2").checked,
 document.getElementById("Field3").checked,
 document.getElementById("Field4").checked,
 document.getElementById("Field5").checked,
 document.getElementById("Field6").checked
 ];

 // Check if at least one field is selected
 var atLeastOneChecked = fields.some(Boolean);

 if (!atLeastOneChecked) {
 alert("Please select at least one option before saving.");
 return false; // Prevent the form from submitting
 }
 return true; // Allow the form to submit
}
</script>

<form onsubmit="return validateForm();">
 <input type="checkbox" id="Field1" name="Field1"> Field 1

 <input type="checkbox" id="Field2" name="Field2"> Field 2

 <input type="checkbox" id="Field3" name="Field3"> Field 3

 <input type="checkbox" id="Field4" name="Field4"> Field 4

 <input type="checkbox" id="Field5" name="Field5"> Field 5

 <input type="checkbox" id="Field6" name="Field6"> Field 6

 <input type="submit" value="Save">
</form>
Steps to Implement:
  1. Add the Script: Place the JavaScript code in the <head> section of your HTML or just before the closing </body> tag.

  2. Modify the Form: Ensure your form calls the validateForm() function upon submission.

  3. Testing: Once implemented, test the form to ensure that it displays the alert and prevents submission when none of the fields are selected.


This JavaScript validation will run on the client side, providing a quick feedback mechanism, and will help ensure that users fill out the required information before submitting the form.

The AI stuff so far to me hasn't been any real help. Below is what I did that appears to work.

if ((values["RelocationPerDiem"] == 0) && (values["RetroEffectiveDateGT60"] == 0) && (values["PosFilledOutsidePosting"] == 0) && (values["PlaceOnPaidAdminLeave"] == 0) && (values["Relocation"] == 0) && (values["PlaceOnUnpaidLeave"] == 0))
{
message = "You must select at least one option in Section 1 to submit this request!";
return false;

}
else
{
return true;
}
