Hey everyone,
I have a wierd issue i can't seem to find out whats going on. I have a
Control for a Shopping Cart Merchant Page called OrderStatus.ascx Inside
that control there is a Repeater with the Products that were ordered on the
ItemCreated event of the repeater i set a property of an options control
within the repeater. The Options control sets a DropDownList and then sets
a SelectedValue.
The Selected Value prop is correct after set, when you get back to the
itemCreated sub it is set there as well, But when it gets out of the
DataBind function and back to the PageLoad sub this value is cleared. Any
idea why anyone?
Here is the code:

OrderStatus.aspx

<asp:repeater id="ProductsRepeater" runat="server">
<itemtemplate>
<tr bgcolor="#ffffff">
<td class="adminBlack" valign="top">
<input type="hidden" runat="server" id="ProductID"
value='<%#DataBinder.Eval(Container.DataItem, "ProductID")%>'>
<asp:textbox runat="server" id="txtQty" cssclass="formText"
text='<%#DataBinder.Eval(Container.DataItem, "Quantity")%>' width="30px">
</asp:textbox><br>
<asp:button runat="server" id="updateQty"
commandargument='<%#DataBinder.Eval(Container.Data Item, "ProductID")%>'
commandname="updateQty" text="Update" cssclass="submitButton">

<td class="adminBlack"><a

"ProductID")%>'><%#DataBinder.Eval(Container.DataI tem, "Name")%></a>
<uc1:productoptionscontrol id="ProductOptionsControl1"
runat="server"></uc1:productoptionscontrol>
</td>
<td class="adminBlack" align="right"
valign="top"><%#String.Format("{0:c}", DataBinder.Eval(Container.DataItem,
"ItemPrice"))%></td>
<td class="adminBlack" align="right"
valign="top"><%#String.Format("{0:c}", DataBinder.Eval(Container.DataItem,
"ItemTotal"))%></td>
</tr>
</itemtemplate>
</asp:repeater>
