In my article "Dynamically linked comboboxes set for ASP.NET", I have represented an ASP.NET custom control realized by a
FrameSet with one hidden aspx file. This hidden file pumps data from database and carries out data to acting page.
At present, browsers mostly support
IFRAME, so we can realize data exchange between pages by this tag and refuse data from
FrameSet. In this case you don’t need to keep HTML file for
FrameSet, in which hidden frame was located. We can link hidden aspx file by
src attribute of
IFRAME or write code directly in
I have carried out the binding code by aspx file and register this script in
OnPreRender method of the custom control class (see CLocate.cs).
string siframe ="<iframe name=\"hidefrm\" " +
"style=\"DISPLAY:none\" src=\"CusControl/HiddenFrm.aspx\">" +
Surely I have made appropriate changes in the client scripts. Now you need not care to link your active page with the
FrameSet HTML file. The pPrevious version of the class
LocControls has been renamed to
Further details can be received from my previous article Dynamically linked comboboxes set for ASP.NET.
To further develop this control you can change LocControl.cs and/or HiddenFrm.aspx.cs and compile once by this command line:
- csc /t:library /out:CusControl.dll CLocate.cs HiddenFrm.aspx.cs.
Client side code is stored in Cuscontrol/usscript.js.
