RadioButtonList: Show selected

Ø

Øyvind Isaksen

I'm making a page to update articles.
When a radiobuttonlist is displayed, I want the stored value to be displayed
as default (checked).

Example: I use a procedure to display the RadioButtonList. An input to this
procedure is the ID that is stored in the database. I want the
radiobuttonlist to show the radiobutton with datavaluefield = savedID as
checked when it is displayed.


Private Sub getTypes(ByVal savedID)
Dim conn As New SqlConnection(variables.ConnString)
Dim cmd As New SqlCommand("spShowType", conn)
cmd.CommandType = CommandType.StoredProcedure

cmd.Connection.Open()
Dim dr As SqlDataReader = cmd.ExecuteReader
Me.radTypeList.DataSource = dr
Me.radTypeList.DataTextField = "content"
Me.radTypeList.DataValueField = "typeID"
'Me.radTypeList.SelectedIndex = savedID

Me.radTypeList.DataBind()
cmd.Connection.Close()
cmd.Dispose()
conn.Dispose()
End Sub


I have tried this:
"Me.radTypeList.SelectedIndex = savedID" does not work.
"Me.radTypeList.SelectedItem = savedID" does not work either.


Thanks for all tips!!!

Hi

I believe radTypeList is name of your RadioButtonList control,
use
radTypeList .SelectedValue =savedID.toString()



e.g

ASP.Net page

<body >
<form id="form1" runat="server" >
<div>

<br />

<asp:RadioButtonList ID="RadioButtonList1" runat="server">
<asp:ListItem Value="1">1</asp:ListItem>
<asp:ListItem Value="2">2</asp:ListItem>
<asp:ListItem Value="3">3</asp:ListItem>
</asp:RadioButtonList>
</form>
</body>



Code behind page (c#)
protected void Page_Load(object sender, EventArgs e)

{

RadioButtonList1.SelectedValue = "2";

}


Hope this will solve your problem..

Hello!

I get the errormessage "Selectedvalue is not a member of
System.Web.UI.WebControls.RadioButtonList" when I try that...
I only have the choices of using "SelectedIndex" or "SelectedItem", there is
no "SelectedValue" on the radiobuttonlist-control.

Strange!?

Hello,

It seems like it has to do with the framework version I use...
I run Visual Studio .Net with framework 1.0 (1.0.3705). I have updated now
Visual Studio with all new service releases, and installed Framework v.1.1
on my computer. But still it seems like visual studio uses framevork 1.0.

Framework 1.0 dont support the "SelectedValue" Property (RadioButtonList
control).
In the Microsoft documentation Microsoft writes: "Note: This namespace,
class, or member is supported only in version 1.1 of the .NET Framework."

Do you know how to fix this??
