问题
I need to built a list of radio buttons, based on data I return from my DB. Each button needs to have a value associated with it that I can get out based on the selected button.
Ideally I would just use the RadioButtonList control, however, I need to have a very custom layout which a RadioButtonList doesn't appear to be able to handle.
An alternative would be to create individual RadioButtons and wrap them in a Panel to group them. However, there doesn't appear to be a Value property on a RadioButton?
Is there an alternative way to set a value to a RadioButton control? Alternatively, a way to completely customise the RadioButtonList output.
At the moment, I'm thinking I might have to resort to using HTML radio buttons with runat="server", must be a better way...?
回答1:
You could create your own radio button class which extends the standard one and adds a value property:
public class ValueCheckBox : System.Web.UI.WebControls.RadioButton
{
public string Value { get; set; }
}
回答2:
You can always try using attributes to save the associated value. eg)
radioButton.Attributes.Add("Key", "Value");
Set the Group property to be the same for all the radio buttons and you should be good to go. Just remember, ASP .Net has a slight problem if these individual radio buttons are in different rows of a repeater, gridview or some such grid-style.

For a quick and dirty set of STATIC radio buttons.
I used the Tag field in the Properties window to manually define a value.
If you are using a DB you should probably bind your data to it. You never know when you'll change a key or name.

RadioButton control doesn't have Value property, that's right. You have to use Checked instead.
