RadioButtonList Binding options Dynamically

RadioButtonList Binding options Dynamically

In general we declare the options of a RadioButtonList control statically in the .aspx page, but what if we need to set these values at runtime based on data from a database, we shall see on how to achieve this.

The Asp.Net RadioButtonList control allows data binding similar to a GridView or Dropdown List control, using which we can bind a data source to the RadioButtonList control.

In the .aspx page just add the RadioButtonList tag without adding any options as follows.

Select Name:

<asp:RadioButtonList

    ID="radListName"

    runat="server"

    RepeatDirection="Vertical">

</asp:RadioButtonList>

Then navigate to the code behind file and add the required options as follows.

protected void Page_Load(object sender, EventArgs e)

{

     radListName.DataSource = dtEmployee;

   radListName.DataValueField = "ID";

   radListName.DataTextField = "Name";

   radListName.DataBind();

}

That’s it we have bound the options to the RadioButtonList control at runtime.
