[liu qingshui]

Now I got a problem that I didn't know how to change another page's control property.

I tried below, but it didn't work.

Label label = (Label)Page.FindControl("chkSpecial"); // I want to change a  label control's Enabled propety,but this control is 

lable.Enabled = true;                                                   //  in another page,I don't know how to find the control in another page.

Thank your kind help!
