radio buttons-web application

[ayush patel]

Hi this is rather a simple question but i dont know why it is creating a problem. i have two radio buttons in a panel and they have to be mutually exclusive. in windows application i know it works well. but here even though i have both the buttons in panel they are not mutually exclusive. i am able to clcik on both of then.

can any one give me a quick response for this.

Use a RadioButtonList instead of individual RadioButtons.

You can use the GroupName attribute to specify a group of buttons that should be mutually exclusive.

Example :

<asp:RadioButton ID="btn1" runat="server" Text="Red" ValidationGroup="type" GroupName="color" Checked="True" />
<asp:RadioButton ID="btn2" runat="server" Text="Blue" ValidationGroup="type" GroupName="color" />
<asp:RadioButton ID="btn3" runat="server" Text="Green" ValidationGroup="type" GroupName="color" />

Actually, RadioButtonList defaults to vertical. However, if you don't like that, do this:

<asp:RadioButtonList id="rbl1" runat="server" RepeatDirection="Horizontal" ></asp:RadioButtonList>
 

You can choose between Horizontal and Vertical alignment.

There is also a RepeatColumns attribute that you can define how many columns of RadioButtons there will be.

Edit: Groupname will work, but I always find the list to be much cleaner. The only reason I use GroupName is when I don't want the radio buttons to be near each other.
