Pushing for Choices with the RadioButton Control

Pushing for Choices with the RadioButton Control

The RadioButton control is a part of the standard ASP.NET control suite, which provides developers with a simple way to allow users to select a single option from a set of mutually exclusive options. When a user selects one option in a group of RadioButtons, all other RadioButtons in that group are automatically deselected. This makes the RadioButton control a useful tool for creating questionnaires, surveys, and other types of user input forms.

To add a RadioButton control to an ASP.NET page, follow these steps:

Open your ASP.NET page in Visual Studio.

In the Toolbox pane, locate the RadioButton control under the “Standard” category.

Drag the RadioButton control onto your ASP.NET page in the desired location.

In the Properties pane, set the Text property to the label that you want to appear next to the RadioButton.

Set the GroupName property to a unique name for the group of RadioButtons that you are creating.

Set the Checked property to True for the RadioButton that you want to be selected by default.

When a user submits the form, the selected value of the RadioButton control can be accessed in the code-behind file using the Request.Form collection. For example, if you set the GroupName property of your RadioButtons to “MyGroup”, you can access the selected value like this:

string selectedValue = Request.Form[“MyGroup”]; This will give you the value of the selected RadioButton in the group. If no RadioButton in the group was selected, the value will be null. You can then use this value to perform whatever action is necessary in your application.
