be sure in SelectedValue and Item..:)
Check it by break point...:)

Use a breakpoint to see what is happening. Make sure this isn't part of an ajax postback.

if (ddlMarkUpType.SelectedValue=="Percent")
{
Label1.Visible = true;
}
this condition is always False.....

Put your dropdown list autopostback=true... and check your asp page for any colliding script or validation...

That gonna solve your problem... Further to short the code dont put the logic in another method.. simply put that in ddl's selected index changed method and try to use .selectedindex rather than selectedvalue to avoid any spelling mistake.
