Web Forms :: Checkbox / Radiobutton Checked - Enabled Textboxes Required?

Jun 15, 2010

I have a radiobutton and if it is checked "Yes", then the three textboxes that are disabled in default will be enable. Now that this textboxes are enabled I want this to be mandatory. How could I do this via javascript or code behind? If I do it in code behind then autopostback is need which is unnecessary.

Web Forms :: Custom RadioButton Loses Checked Value On PostBack?

Jan 28, 2010

I am creating a control that inherits from the RadioButton, so that I can set the GroupName property manually. Everything is working okay apart from the fact that when the page posts back, the RadioButton becomes unchecked if it has previously been checked. This is the first time I've tried inheriting from controls, so must be doing something really silly. I would welcome anyone helping me to improve my code so that the control's Checked value persists through postbacks. I am causing a postback using a button, not the actual RadioButton itself, if that makes any difference. Here is my code:

Web Forms :: RadioButton - Dynamically Created Not Retaining Checked Value After Postback

Jan 13, 2011

I have a couple of RadioButtons that are created dynamically. But after postback they don't retain their checked property. I also have some CheckBoxes and they work just fine using the same mechanism (code below). I have narrowed down the problem to the "GroupName" property. If I remove it, it works just fine. But I need the RadioButtons to be mutually exclusive.

Web Forms :: Clearing Textboxes On A Generated Table Based On Radiobutton Or Dropdownlist?

Oct 5, 2010

I have code that another member assisted with and is working great. Now that the page is working more and more like it should with the remaining requirments. I have something else i would like to implement.

Since the code i have automatically creates / generates a table with textboxes and labels based on a drop down selection. I would like to know how to clear the textboxes if they chose 0 from the dropdown. Or if they select "No" on the radiobutton, then that means they have nothing to provide, so i dont want to capture something that they may have entered before changing their mind.

Here is the code the generates the tables and textboxes, i just need to setup, so that if they select "NO" from the radiobutton or if they select "0" from the dropdown that the textbox values, if any, are cleared so that we dont get inconsistant data captured.

Radiobutton In Group (GroupName) Are All Checked?

Jul 22, 2010

So I've got three RadioButtons, They're not in a RadioButtonList because I need to add some textboxes next to each of them.I've added a GroupName, and on the front end they behave as expected. ONLY ONE appears checked at a time.However in the code, if I do:

RadioButton1.Checked = true;
RadioButton2.Checked = true;
RadioButton3.Checked = true;

I would expect only the last one, RadioButton3, to be checked, because they all belong to the same group. This is not the case. All three evaluate to true.... how can that be?

.net - Check If A Radiobutton Is Checked In A Group?

Aug 11, 2010

I have group of radio buttons, each group ranges from 5 - 27 radiobuttons. And if any radio button in a group is checked I store 1 in db else I store 0. Now I'm checking each radiobutton using if loop to see if they are checked and set database value. I'm also trying to use the code below. Is there a good/better approach to check if they are checked or not?Current code:

'rname is radiobutton prefix for a given group
'cnt is number of radiobuttons in the group
Private Function RadioIsChecked(ByVal rname As String, ByVal cnt As Integer) As Integer
