Loading time when changing the content of a RadPanel

Hello,

I have a list of items in a RadPageViewPage, in which I can select an item. A specific view for the selected item, depending on its type, is displayed in another RadPageViewPage. I then have to change the content of the panel in the second RadPageViewPage depending on the selected item, which is done simply with the following code:

           1 UserControl userControl = new UserControlRobotActionProcess();
           2 userControl.Parent = radPanel1;

I observed it took quite long to display the UserControl in the panel and measured the time of the line of code 2 above: 400ms. I then tested to display the same control, but with standard WinForms controls instead of the Telerik ones. The same line of code takes 1ms.

I think that the views I use could be optimized and could be loaded faster. I attach a screenshot of the view I have loading time issues with. Here is also the list of Telerik controls I use:

- RadSpinEditor

- RadPanel

- RadPageView

- RadPageViewPage

- RadLabel

- RadGroupBox

- RadButton

- RadRadioButton

- RadCheckBox

- RadTextBox

Do you know if I can improve the loading time of this UserControl?

Please feel free to tell me if you need more information.

Kind regards,

Antoine
