Hello i am trying to display product name in a dropdown lost and when the index is changed am showing another list of the products under that product name category and further models of that category.
My code is here
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true" ><ContentTemplate> <tr><td class="auto-style3">Equipment Name</td><td><asp:DropDownList ID="equipment_name_DropDownList" runat="server" AutoPostBack="True" DataSourceID="SqlDataSource1" DataTextField="product_name" DataValueField="product_name" OnDataBound="equipment_name_DropDownList_DataBound" OnSelectedIndexChanged="equipment_name_DropDownList_SelectedIndexChanged"></asp:DropDownList><asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:RegConnectionString %>" SelectCommand="SELECT DISTINCT [product_name] FROM [Products]"></asp:SqlDataSource></td></tr><tr><td class="auto-style3">Equipment Make</td><td><asp:DropDownList ID="equipment_make_DropDown" runat="server" AutoPostBack="True" OnDataBound="equipment_make_DropDown_DataBound" OnSelectedIndexChanged="equipment_make_DropDown_SelectedIndexChanged"></asp:DropDownList></td></tr><tr><td class="auto-style3">Equipment Model</td><td><asp:DropDownList ID="equipment_model_DropDown" runat="server" OnDataBound="equipment_model_DropDown_DataBound"></asp:DropDownList></td></tr></ContentTemplate><Triggers><asp:AsyncPostBackTrigger ControlID="equipment_name_DropDownList" EventName="equipment_name_DropDownList_SelectedIndexChanged" /><asp:AsyncPostBackTrigger ControlID="equipment_make_DropDown" EventName="equipment_make_DropDown_SelectedIndexChanged" /></Triggers></asp:UpdatePanel>
This refreshes the whole page and not just the update panel.Please help about where i go wrong.
Thank You.
