checkbox

问题 I have a TreeView populated with TreeNodes having icons and checkboxes. I've been tryig to disable the checkig/unchecking ability of some of them discarding the event in the BerforeCheck method. This works fine, until I double click on the checkbox: the image of the checkbox is the opposite of its real state (it shows a check mark if the status is Checked=false ). I've tried to fix that changing the StateImageIndex manually in the NodeDoubleClick and BeforeClick method with no success. Even

问题 I'm creating a form in Django (using ModelForm). There are many checkboxes, and I want to make it so that one of these must be selected in order to submit the form. I don't mean any one checkbox, but one specific box. I can't find anything in the Django documentation. Any help would be appreciated. 回答1: Something like from django import forms class MyForm(forms.Form): check = forms.BooleanField(required = True) # your other form fields For a BooleanField, required = True will check if the box

问题 Is there a way to put the checkbox to the right of the label on an asp checkbox? This code by default places the checkbox then the label... <asp:CheckBox CssClass="myCheckbox" ID="CBmyCheck" runat="server" Text="My label"></asp:CheckBox> 回答1: One simple solution is create two seperate objects, one checkbox and one label. The checkbox label should be set to "" (that is nothing). The label should be set to "My Label". Place them where you want, in addition, first add the label and then place

问题 I made checkboxes using the following rails form helper: <%= check_box("tag", tag.id) %> However, I need to make some of them checked by default. The rails documentation doesn't specify how to do this. Is there a way? How? 回答1: This has a very straightforward solution that is directly supported by check_box (at least as of rails 4, I didn't check older documentation) <%= check_box("tag", tag.id, {checked: true}) %> This will make the checkbox checked. Of course instead of true you will put in
