Validation Logic
- by user2961971
I am trying to create some validation for a form I have. There are two text boxes and two radio buttons on the form. My logic for this validation I know is a little rusty at the moment so any suggestions would be great.
Here is the code for what I have so far:
Keep in mind that the int errors is a public variable in the class
Start Button code:
private void btnStart_Click(object sender, EventArgs e)
{
errors = validateForm();
//Here I want the user to be able to fix any errors where I am little
stuck on that logic at the moment
//validate the form
while (errors > 0)
{
validateForm();
errors = validateForm();
}
}
ValidateForm Method:
private int validateForm()
{
errors = 0;
//check the form if there are any unentered values
if (txtDest.Text == "")
{
errors++;
}
if (txtExt.Text == "")
{
errors++;
}
if (validateRadioBtns() == true)
{
errors++;
}
return errors;
}
ValidateRadioBtns Method:
private Boolean validateRadioBtns()
{
//flag - false: selected, true: none selected
Boolean blnFlag = false;
//both of the radio buttons are unchecked
if (radAll.Checked == false && radOther.Checked == false)
{
blnFlag = true;
}
//check if there is a value entered in the text box if other is checked
else if(radOther.Checked == true && txtExt.Text == "")
{
blnFlag = true;
}
return blnFlag;
}
Overall I feel like this can somehow be more stream lined which I am fairly stuck on. Also, I am stuck on how to ensure the user can return to the form, fix the errors, and then validate again to ensure said errors are fixed.
Any suggestions would be greatly appreciated since I know this is such a nooby question.
