    Hello all,
    Recently for a project i needed to install the Telerik component package because the project which was handed over to me for further development process were heavily based on Telerik components ( such as themes,Gridviews,Buttons ,ComboBoxes,etc) i tried installing RadControls_WinForms_2010_1_10_308_dev that i already had on my Visual Studio 2010Sp1 .
    after installing that and running the project for the first time , i noticed an extreme lag in using Visual Studios . even renaming a buttons name would take more than a minutes , let alone navigating through toolbox , dragging new item and start working on them! (another example is when i click on the run project in visual studio , the application takes from say 30 seconds to sometimes 2~5 minutes to execute!!, i get multiple designer time exceptions as well ! which is bad , very bad!)
    the lag is so extreme that a process which would take me only 30 minutes in a normal form application , takes more than 3 hours and so on ! which is extremely bad . 
    now i want to know if this is normal with teleriks components , since if it is that heavy and resource intensive , we should definitely put it aside and start using sth else . if it is not what would be the cause  ?
    (please note that in the current project , there are 17 RadGridViews plus other Teleriks Components such as RadTextBoxes and RadLabels and so on - i said it because i thought it might be better told )
    Ok , now what is the problem in case there is a problem ?

    Hello Hossein,

    No, this is definitely not normal. It seems to be a serious issue, however we have not observed it before and I am not able to identify it by using the provided information. I noticed that you are using a quite old version of RadControls for WinForms. That is why I recommend that you try our latest release - Q2 2012 SP1. If the issue continues to appear, please send us your application and we will research the case further. 

    Should you have any further questions, do not hesitate to ask.
    Kind regards,
    the Telerik team
