deleting selected button that are in gray color

Hi, you have not mention that button where in place. I mean in grid view and place holder. I assume that your button place on windows form. If am wrong plz correct to me.

Listlist=newList();
GetAllControl(this,list);
foreach(Controlcontrolinlist)
{
if(control.GetType()==typeof(Button))
{
Buttonbutton=typeof(Button);
if(button.ForeColor==Color.Gray)
{
button.Visible=false;//Hidebutton
button=null;
this.Controls.Remove(button);//RemoveButton
}
}
}
privatevoidGetAllControl(Controlc,Listlist)
{
foreach(Controlcontrolinc.Controls)
{
list.Add(control);
if(control.GetType()==typeof(Panel))
GetAllControl(control,list);
}
}
