Hello,
How can get a value of the DropDownWindowTemplate of the ASPxDropDownEdit Control.
The control into DropDownWindowTemplate is a ASPxMemo.
Thanks,

Hello Juan Carlos,
Thank you for providing your project. When you are using the ASPxDropDownEdit, it is necessary to synchronize values of the editors inside DropDownWindowTemplate with the ASPxDropDownEdit's value. You can implement this by using the following code:
[ASPx]
<dx:ASPxDropDownEdit ID="ASPxDropDownEdit1" runat="server" ReadOnly="true" ClientInstanceName="dde"> <DropDownWindowTemplate> <dx:ASPxMemo ID="ASPxMemo1" runat="server" Height="71px" Width="170px"> <ClientSideEvents TextChanged="function(s, e) { dde.SetText(s.GetText()); }" /> </dx:ASPxMemo> </DropDownWindowTemplate> </dx:ASPxDropDownEdit>
This way, you can get the ASPxDropDownEdit's value either on the server or client side. In addition, if you want to get a reference to the controls inside DropDownWindowTemplate, use the ASPxDropDownEdit.FindControl method:
[C#]
ASPxMemo memo = ASPxDropDownEdit1.FindControl("ASPxMemo1") as ASPxMemo;
Attached is the modified project. Please let me know if you need further assistance.
