  3. Select the project in Solution Explorer.

  4. In the Project menu, click Add New Item.

  5. In the Add New Item window, expand the Visual C# group of installed templates.

    • EP User Control

    • EP Chart Control

  8. Name the new User Control.

  9. Click Add.

Designing a New User Control

  5. If required, add any code to the markup or the code-behind file for the User Control.

  6. Save the User Control by making the .ascx file for the control active in Visual Studio, and then clicking Save in the File menu. The control will be saved. It will also be and added to or updated in the AOT.

Compiling a New User Control in the AOT

To have security work correctly for the new User Control, you must compile it the AOT. Be sure that the new User Control has been saved in Visual Studio, which will add the User Control to the AOT.

  2. Expand the Web Controls node and locate the new User Control that you created.

  3. Right-click the new User Control and then click Compile.

  4. Verify that there are no compiling errors. If there are, correct them in Visual Studio and then compile again.
