Vb net radiobutton validating
control has its name from old analog radios which had a number of programmable station buttons. To define which Radio Buttons belong togehter, you have to set the Amazaed to see so many dumb People.
When you pushed one in, the previosly selected poped out. They are reading this and they dont know what data binding is.
It the list of options gets longer, you should prefer a combo or list box instead.
It would have been better for lame user to understand if it had the solution/source code file with this in zip. They are reading this and they dont know what data binding is.
Any help would be greatly appreciated ADDED: Here is the datalist. Checked = True) End Sub Protected Sub questiongroup_Server Validate(By Val source As Object, By Val args As Server Validate Event Args) Dim rb As Radio Button = Try Cast(source, Radio Button) args. Find Control will only find controls which are directly placed inside and not their child controls.
Here's a sample code Hi, The code you have given is not good. I assume you are doing so so that you can make them visible false as per need.
this is not an issue when using a different parent for each radiobutton as a means of seperating them into different groups... I followed the instructions exactly, but my databound value is not being updated when the radio buttons are clicked.Private Function Validate Discount Selected(By Ref bln Discount As Boolean, By Ref str Discount As String) As Integer ' This function confirms the user selected a discount available. Msg Box("Please Select If Discount Is Available", , "You must Choose A Discount If Avaiable") bln Discount = False End Try Return int Discount Selected That code tries to convert an entire controls collection to an integer, which cannot ever work. You apparently want to know which control is checked, but that alone will not tell you the Discount level desired: a control which says "2% Discount" is not the same a objects, where the text says "10%" or whatever, while returning a numeric value to your code.Dim int Discount Selected As Integer Try int Discount Selected = Convert. Basic class to keep a name/text and value together.So, in a style that's applied to your Radio Buttons: "If you bind the Is Checked property to a boolean and check the Radio Button, the value gets True.But when you check another Radio Button, the databound value still remains true." I am using WPF 4.0 with 4.0, this issue is fixed. But I've got a little problem, I have a tab Control and each tab Item have a different opacity, on right click it open a context menu with radion button witch allow to change it, everything goes right, on each tab Control radiobutton is set to the correct value, but as soon as I changed a value (it's correctly set) if I click on another tab Item (the opacity is still ok) the context menu show the opacity I've set the the last one... Thank you in advance I've tried this technique and it does not work at all.
