I have Custom web control(Composite control) contains fileupload funactionality and also displaying dynamically generated controls on some portion of it. When I do perform a postback like uploading file on the Custom control, the dynamically generated controls are lost and not displaying on it. The requirement is always it should retain the data of dynamically generated controls even any postback has performed. Could you please let me know how to proceed on this.
I tried applying updatepanel to the fileupload control on the Custom control. it did not work and lost the dynamically generated controls portion when file upload performs.
