I have a button " TrnsButton" in ViewComplaint.aspx page. Now i wanna access the button from my usercontrol which is caseStageTransition.ascx.cs. so I did the below code in the user control class.Im casting the page to Viewcomplaint then i was able to get the fincontrol intelisence. and now I''m trying to pass the button in findcontrol. the error i''m getting is

Button v = ((ViewComplaint)Page).FindControl("TrnsButton");

1)错误非静态字段，方法或属性``System.Web.UI.Control.Page.get''需要对象引用
2)错误无法将类型"System.Web.UI.Control"隐式转换为"System.Web.UI.WebControls.Button".存在显式转换(是否缺少转换?)

1) ErrorAn object reference is required for the nonstatic field, method, or property ''System.Web.UI.Control.Page.get''

2) Error Cannot implicitly convert type ''System.Web.UI.Control'' to ''System.Web.UI.WebControls.Button''. An explicit conversion exists (are you missing a cast?)

推荐答案

对于错误2，您需要转换为Button

For error 2 you will need to cast to Button

Button v = (Button)((ViewComplaint)Page).FindControl("TrnsButton");
