    I want to create a web control that has a RadInputmanager , and i am having the follow exception .
    [NullReferenceException: Object reference not set to an instance of an object.]
    System.Web.UI.Control.FindControl(String id, Int32 pathOffset) +219
    System.Web.UI.Page.FindControl(String id) +38
    Telerik.Web.ChildControlHelper.FindControlRecursive(Control searcher, String ID) +68
    Telerik.Web.UI.RadInputManager.PopulateInputCollection() +401
    Telerik.Web.UI.RadInputManager.OnPreRender(EventArgs e) +454
    System.Web.UI.Control.PreRenderRecursiveInternal() +90

    here is the base code
       private RadInputManager inputManger = new RadInputManager();
            private TargetInput target = null;
            CPFTextString cText = new CPFTextString(); // ibased om  public class CPFTextString : RegExpTextBoxSetting
            public CPFControl()
                : base()


            protected override void OnInit(EventArgs e)
                target = new TargetInput(cBox.ID,true );

    Hello Ricardo,

    Could you please try first adding the RadInputManager to the controls collection and then adding target inputs for its setting? Give it a try and let me know if it makes any difference.

    All the best,
    the Telerik team
