Q & A @ Customize End-User Report, but ,....

Question Can the End-User report designer be customized? Answer It is possible to create a custom End-User Report Designer. You should do the following: A) Create a descendant from the XRDesignForm class and customize it according to your requirements. B) Use the following code to open the designer: MyDesignForm designer = new MyDesignForm(); designer.OpenReport(myReport); designer.Show(): This is the answer i get corresonded to the question i've asked. I've tried it but still it doesnt seems to work. Can anyone teach what should i do base on the code given above .? How do i create a descendant from the XDesignForm Class ? I cant find the XDesignForm class tho. Is the class is already in embeded in the C# language ? Or do i need to create my own ? Hope someone can help as im just a newbie programmer. Thanks in advance .
