I am attempting to create a radiobuttonlist as a result of value retrieved from the db. In the db i have a name of picture file in which i will return. I want the radiobuttons to interpret this value and populate an image. I am currently doing this with an image displaying in a datagrid but not for a radiobutton.

Here is what i have, but it will not retrieve the image?

<asp:RadioButtonList id="RadioButtonList1" runat="server">
<asp:ListItem >
<img src='/pic_directory_here/ <%# fixpicture(Container.DataItem("pic_name_here")) %>
</asp:ListItem>
</asp:RadioButtonList>

1) Your image tag is not complete. It should be:

<img src='/pic_directory_here/<%# fixpicture(Container.DataItem("pic_name_here"))%>'>

(quote and closing tag at the end)

2) Did you look at (can you show us part of) the html generated when the page is rendered?


3) Can you show us your databind() code for the radiobuttonlist?

4) Try this

<img src='/pic_directory_here/<%# Container.DataItem("pic_name_here")%>'>

to see if there is a problem with your fixpicture method.

Ron,

I tried this and it still will not find my images. Here is what the HTML translated to:

<ItemTemplate>
<asp:RadioButtonList id="RadioButtonList1" runat="server">
<asp:ListItem >&lt;img src='/peifootball/gifs/&lt;%# Container.DataItem(&quot;team_pic&quot;) %&gt;' &gt; </asp:ListItem>
</asp:RadioButtonList>
</ItemTemplate>
</asp:DataList>

How does the databinding work with the radiobutton list? I am only databinding the datalist.

I was asking about the HTML that is rendered in the client. Look at that and see if there is an <img src

-ron

<img src='/peifootball/gifs/<%# Container.DataItem("team_pic") %>' >

I am not sure if this is what you want but this is what is generated. I am just not sure if radiobuttons can be generated from a file name retrieved from the database. It will work if i hard code the name of the file into the img src but not when i bring in the db value.

Try this:

    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load


        If Not IsPostBack Then


            GenImage()


        End If





    End Sub





    Sub GenImage()


        Dim a As ArrayList = New ArrayList


        a.Add("bl.gif")


        a.Add("bc.gif")


        a.Add("cc.gif")


        For Each s As String In a


            RadioButtonList1.Items.Add(New ListItem("<img src=""" + s + """/>", s))


        Next


    End Sub

and this on the html page

<asp:RadioButtonList id="RadioButtonList1" runat="server"></asp:RadioButtonList>

 The ListItem tag should contain a "value" attribute for the image to appear. ;)

Hi, I am facing the same problem.

Following is my aspx code :

<tr><td >asp:RadioButtonList ID="rlCards" runat="server"></asp:RadioButtonList></td></tr>

aspx.cs code is :

string img1 = "<img src='images/ <%# fixpicture(Container.DataItem(\"card"+Card.CardId+".jpg\")) %>'>";

ListItem listItem = new ListItem(img1, Card.CardId.ToString());

rlCards.Items.Add(listItem);

 

I want my radiolist rlCards to be associated with the images in folder images and image name as (card+cardId).jpg

Is there any way, I can get that correctly.

Thanks in advance.

I know ot was too late then, but somebody might be looking for the same solution.

Maybe you could try this solution.

<asp:RadioButtonList id="RadioButtonList1" runat="server"> 
<asp:ListItem > 
<%# "<img src=\"/pic_directory_here/" +  fixpicture(Container.DataItem("pic_name_here").ToString()) + "\"" %> 
</asp:ListItem> 
</asp:RadioButtonList>
