How to bind dropdownlist in EditItemTemplate in FormView control?

Using Visual Web Developer Express 2010 with ASP.NET 4.0.

I have a FormView and I want to set a default value from the database. I can't get it to bind to the value in the database. My FormView looks like this:

<asp:FormView 
ID="frmOrderDetails" 
DataSourceID="sdsFormOrderDetails" 
runat="server" 
DataKeyNames="orderId">

<EditItemTemplate>
    <h3>Edit Order Details</h3>

    <asp:Label ID="lblStrategy" Text="Strategy:" AssociatedControlID="ddlStrategies" runat="server"  />
    <asp:DropDownList SelectedValue='<%# Bind("strategyId") %>'
开发者_运维问答    ID="ddlStrategies" 
    runat="server" 
    DataTextField="strategy" 
    DataValueField="strategyId" 
    DataSourceID="sdsStrategies"
     />

    <asp:LinkButton
    id="lnkUpdate"
    Text="Update Order"
    CommandName="Update"
    Runat="server" />
    |
    <asp:LinkButton
    id="lnkCancel"
    Text="Cancel"
    CommandName="Cancel"
    Runat="server" />

</EditItemTemplate>
</asp:FormView>

<asp:SqlDataSource ID="sdsFormOrderDetails" runat="server" 
    ConnectionString="<%$ ConnectionStrings:LocalSQLServer %>" 
    ProviderName="<%$ ConnectionStrings:LocalSQLServer.ProviderName %>"  
    SelectCommand="usp_GetOrderDetails" SelectCommandType="StoredProcedure" 
    UpdateCommand="usp_UpdateOrder" UpdateCommandType="StoredProcedure">
    <SelectParameters>
        <asp:ControlParameter Name="orderId" ControlID="grdOrders" PropertyName="SelectedDataKey.Value" />
    </SelectParameters>
    <UpdateParameters>
        <asp:ControlParameter Name="orderId" ControlID="grdOrders" />
    </UpdateParameters>
</asp:SqlDataSource>                     

<asp:SqlDataSource ID="sdsStrategies" runat="server"
    ConnectionString="<%$ ConnectionStrings:LocalSQLServer %>" 
    ProviderName="<%$ ConnectionStrings:LocalSQLServer.ProviderName %>"  
    SelectCommand="usp_GetStrategiesDropDown">   
</asp:SqlDataSource>    

The EditItemTemplate does not even load when I click the edit button on my FormView control, but I don't get an error message either.

You need to do the following to bind a DropDownList to the EditItemTemplate:

1. Add the DropDownList and its DataSource to the EditItemTemplate.

2. Set the DropDownList parameters:

   DataSourceID="SqlDataSourceDropDownlist" SelectedValue=<%# Bind("ValueToBind") %>
   DataTextField="ValueToDisplay" DataValueField="ValueToBind"
   

3. Set the ListView / FormView DataSource <UdateParameters>: <asp:Parameter Name="RankID" Type="Int32" />

you need to use formview Databound event like

 protected void frmOrderDetails_DataBound(object sender, EventArgs e)
{
    if (frmOrderDetails.CurrentMode == FormViewMode.Edit)
    {
        DropDownList ddlStrategies = (DropDownList)frmOrderDetails.FindControl("ddlStrategies");
        ddlStrategies.SelectedValue = Your DB Value Goes here;
    }
}
