asp:Image - tag in repeater

Why does the second line work but not the first one? I get the "The server tag is not well formed". And the Guid I've copy into the second line is directly from the database. 

< asp:Image runat="server" ImageUrl="~/Images/Avatar/Avatar.aspx?UserId=<%#DataBinder.Eval(Container.DataItem, "UserId")%>" />

< asp:Image runat="server" ImageUrl="~/Images/Avatar/Avatar.aspx?UserId=22AA736E-BD1B-4623-8E76-4769051F2E60" />

An alternative method is to use String.Format(...).

<asp:TemplateField HeaderText="Avatar" SortExpression="LastName, FirstName">
    <ItemTemplate>
        <asp:Image ID="Image1" runat="server" ImageUrl='<%# String.Format("~/Images/Avatar/Avatar.aspx?UserID={0}", Eval("UserID").ToString()) %>' />
    </ItemTemplate>
</asp:TemplateField>

Try printing you <%#DataBinder.Eval(Container.DataItem, "UserId")%> in a label. The way a Guid is formatted might not be exactly like what it looks like in the database. If i remeber correcctly, it might had {} around the Guid.

Or try

< asp:Image runat="server" ImageUrl='<%#"~/Images/Avatar/Avatar.aspx?UserId=" + DataBinder.Eval(Container.DataItem, "UserId")%>' />

Your problem was the double quotes. Your opening quote was a double quote so was being closed by the opening quote on "UserID". You should also always use single quotes when databinding anyway.

Put single quote around value of ImageUrl attribute.

<asp:Image runat="server" 
           ImageUrl='~/Images/Avatar/Avatar.aspx?
              UserId=<%#DataBinder.Eval(Container.DataItem, "UserId")%>' />
