Hallo.
Either I am a noob, or something strange is going on .
I have got an ASP.net webform , on this form I have a object datasource ( which is linked to my class).
When I add a form view to the form and link it to my object datasource the template is not generated for me. I need to manually build the template. It is if the formview does not see the objectdatasources select,insert etc commands. The class I am linking to, does work.
please help, i think somewhere I am missing a property or something.
kind regards

Im using Bitmap to Draw the graphs using GDI+ objects, every time while loading the new graph the "PF usage" (memory size) keeps adding by 20 or even more.. how to destroy the current instance of a GDI+ object used to draw a graph or how to re-use the same Bitmap to draw new graph keeping the memory size constant.
please help me out ni this asap.

Call Dispose when you finish with a bitmap to clean up it's memory usage.

Did you read Christian's reply? Are you disposing your bitmaps?
Memory is managed by the framework - you can't expect the memory use
to go back to what it was before you create an object.

CrystalReportViewer control  is disable in the Toolbox.How to make it enable (.Net2.0)
|
|
|
|
|
If you have selected Crystal Reports Application while creating the project I believe that you should have the viewer as enabled by default.
But if you have started with Windows Application, I can suggest you to make sure that your solution has a reference to Crystal Reports Engine.

OK. Obviously also a new user of this website. You asked in the ASP.NET forum, I think. Don't ask here, this is for non ASP.NET questions.
