ASP.NET repeater user control not displaying data

Question

I have a user control that contains a repeater. I populate the datasource for the repeater (I have checked it contains data) but the repeater doesn't display any data. The control has been added to the page correctly.

 //aspx for user control
 <asp:Repeater runat="server">
        <HeaderTemplate><table>
        <%# Eval("Name") %>
 </HeaderTemplate>

 //C# for user control
 public object DataSource { get; set; }
 protected void Page_Load(object sender, EventArgs e)
    {
        this.DataSource = DataSet;
        this.DataBind();
    }

//C# (code behind of aspx page where I want to use the repater user control)
repeater.DataSource = DataSet.ToArray();
repeater.DataBind();

Any ideas why this isn't working?

is this your real markup or just sloppy copying and pasting? — Tim B James

Try this way :

    <asp:Repeater ID="repeater1" runat="server"> 
            <HeaderTemplate>
                <table class="datatable fullwidthpercent"> 
                   <tr>
                       <td>Name</td>
                   </tr>
            </HeaderTemplate>
            <ItemTemplate>
                   <tr>
                       <td><%# Eval("Name") %></td> 
                   </tr>
               </table>
            </ItemTemplate>
            <FooterTemplate>
               </table>
            </FooterTemplate>
   </asp:Repeater>

and also write repeater1.DataBind(); after assigning datasource property.

Thanks for your reply, I added this. I used the debugger and the datasource is being populated for the user control and databind() is called but data is still not displayed.

I used the aspx from your answer. I think the problem might be with the data binding, do you need to bind it in the page load method of the user control or in the code behind of the file you want to use the user control in?

you need to bind it in user control only where you can access repeater1.

Thanks for your help - I didn't have an ID attribute for the reapeter user control. I added the following code to the repeater user control code behind: this.repeater1.DataSource = DataSource;

repeater1.DataBind(); Is what worked for me!

repeater.DataBind();

ASP.NET controls do not bind automatically.

DataBind() may need to be called, but I think OP also needs to use the ItemTemplate

HeaderTemplates, I believe, don't bind data, they only display static content. You have to put data to bind in the ItemTemplate or AlternatingItemTemplate.

I assume you omitted the DataBind statement from this, that needs to be called too.

I moved the Eval("datavalue") to the itemtemplate and bind is there I didn't include it in the question.

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        getdata();
    }

}
public void getdata()
{
    ds = objfun12.display();
    repeat12.DataSource = ds;
     repeat12.DataBind();

}
