server control onclick error

Question

Hi,

I am using a datalist inside which I have defined an itemtemplate. I am using asp:LinkButton inside this itemtemplate. I have used an OnClick="methodname" in this linkbutton tag. I have the corresponding mehtodname defined in my code behind, However I keep getting a Java runtime error when the page loads up and when I click on any of the items in the datalist. It says that I have not javascript function function defined with the name mentioned.

Isnt asp:LinkButton a server control. I want to use my c# code behind and not javascript. How do I proceed??

<asp:DataList ID="DLID" RepeatColumns="5" RepeatDirection="Horizontal" runat="server">

<ItemTemplate>
<div class="home">
<div class="homeblock"></div>
<div class="homeitem">
<ul><li><span style="font-size:small;">
<asp:LinkButton ID="TopItem" runat="server" OnClick="Item_OnClick"><%# Container.DataItem %></asp:LinkButton>
</span></li></ul>
</div>
</div>
</ItemTemplate>
</asp:DataList>

Just put the C# code/logic in the asp:LinkButton Click Event.

Works perfectly fine for me. Used your markup code minus the class names. Here is the code-behind I used:

protected void Page_Load(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
        string[] ds = new string[] { "a", "b", "c", "d", "e", "f", "g" };
        DLID.DataSource = ds;
        DLID.DataBind();
    }
}

protected void Item_OnClick(object sender, EventArgs e)
{
    //do stuff
}

What is the exact error message?
