This is because you are not telling f2 who its Parent is. If this is an MDI application, then f2 should have its MdiParent set to f1. Form f2 = new Form() { Width = 400, Height = 300 }; f2.StartPosition = FormStartPosition.CenterParent; f2.MdiParent = f1; f2.Show(); If this is not an MDI application, then … Read more
strip_tags actually removes the tags from the input, which may not be what you want.

is_valid() calls clean() on the form automatically. You use is_valid() in your views, and clean() in your form classes. Your clean() function will return self.cleaned_data which if you will notice in the following view is not handled by you as the programmer. form = myforms.SettingsForm(request.POST) if form.is_valid(): name = form.cleaned_data[‘name’] #do stuff You didn’t have … Read more

For example – for validation purposes See the below code and see how it can be beneficial: <script language=”JavaScript”> myFunctionName() { if (document.myForm.myText.value == ”) return false; // When it returns false – your form will not submit and will not redirect too else … Read more
HTML If you’re trying to do this strictly with HTML, I believe the following is going to get you about as close as is currently possible: <label for=”ccn”>Credit Card Number:</label> <input id=”ccn” type=”tel” inputmode=”numeric” pattern=”[0-9\s]{13,19}” autocomplete=”cc-number” maxlength=”19″ placeholder=”xxxx xxxx xxxx xxxx”> inputmode sets the keyboard type (in this case, numeric) pattern enables validation (in this … Read more
