Question

Is there a way to hide radio buttons inside a RadioButtonList control programmatically?

Answer 1

Under the hood, you can access the attributes of the item and assign it a CSS style.

So you should be able to then programmatically assign it by specifying:

RadioButtonList.Items(1).CssClass.Add("visibility", "hidden")

and get the job done.

'CssStyle' is not a member of 'System.Web.UI.WebControls.ListItem'. I understand setting visibility, but not sure where the CssStyle property is coming from... – Rippy

Ahh, an old typo, it should have been the CssClass property and not CssStyle. I've updated things accordingly. – Mho

'CssClass' is not a member of 'System.Web.UI.WebControls.ListItem'. Sorry :P – Rippy

Correct, but it is part of it's parent WebControl class and should be inherited down. (See: msdn.microsoft.com/en-us/library/…) You might need to check your references if you're not seeing it in your intellisense. – Mho

Answer 2

Here's how you have to apply a style attribute to a listitem:

RadioButtonList.Items(1).Attributes.Add("style", "display:none")
- OR -
RadioButtonList.Items(1).Attributes.Add("style", "visibility:hidden")

Answer 3

Why not add and remove the radio buttons as needed?

RadioButtonList.Items.Add("Item Name" or index);
RadioButtonList.Items.Remove("Item Name" or index);

Try This:

RadioButtonList.Items.Remove(RadioButtonList.Items.FindByValue("3"));

Answer 5

If you mean with JavaScript, and if I remember correctly, you've got to dig out the ClientID properties of each <input type="radio" ...> tag.

Answer 6

Have you tried to hide it through the itemdatabound event onload or do you need it to hide after it loads?

Answer 7

I haven't tested it, but I'd assume (for C#)

foreach(ListItem myItem in rbl.Items)
{
if(whatever condition)
myItem.Attributes.Add("visibility","hidden");

}

Sorry @James, visibility is a style not an attribute. – Rippy

Yeah agreed. That was way back in the day before i knew CSS really well. – Mongeau

Answer 8

Another answer to not visibility inside a RadioButtonList.

Try this code:

RadioButtonList.Items(1).CssClass.Add("display", "none");

and get the job to no display RadioButtonList in layout.
