Validation: Making sure a RadioButton is selected

Nathan Sokalski

I have a set of RadioButtons in my form. I want to make sure that the user
selects one of them, and therefore am initially having none of them
selected. However, I want an error message to be displayed if they attempt
to submit the form without selecting one of them the same way an error
message would be displayed by a RequiredFieldVa lidator or any of the other
validation controls. However, because the RadioButtons are separate
controls, I cannot use the CustomValidator because I cannot put more than
one control in the ControlToValida te property. Is there a way to use any of
the validation controls to achieve this? I would prefer to use a validation
control so that I can include the error in the ValidationSumma ry control.
Thanks.

Use a RadioButtonList . Add you items to the list. Set the ControlToValida te
of your RequiredFieldVa lidator to the RadioButtonList .

tkinter radiobutton

by: William Gill | last post by:

I am placing radiobuttons in a 4 X 4 matrix (using loops) and keep references to them in a 2 dimensional list ( rBtns ). It works fine, and I can even make it so only one button per column can be selected, by assigning each column to an intVar. In many languages a radiobutton has a property that can be directly read to see if it is selected on unselected. Tkinter radiobuttons don't seem to have any such property. Is there any way to...

Triggering client-side validation manually

by: Nathan Sokalski | last post by:

I have written a Validator (a class that inherits from the BaseValidator class), and it includes client-side validation functions. The validator is a conditional validator that only validates if a specified checkbox, radiobutton, dropdownlist item, etc. is checked or selected. The only feature I have left to add is to hide the error message if they uncheck or unselect the checkbox or radiobutton by use of the onchange eventhandler. Is...

Problem With Comparison Operator <=> in G++

by: Oralloy | last post by:

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

The easy way to turn off automatic updates for Windows 10/11

by: Hystou | last post by:

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
