What do you mean by drag? Reordering the columns or changing the column size?

Reordering of report list columns is enabled by setting the extended style LVS_EX_HEADERDRAGDROP of the list control:
SetExtendedStyle(GetExtendedStyle() | LVS_EX_HEADERDRAGDROP);

to change column size am unable to drag the header..

As far as I know the resizing feature is always enabled. But it may be disabled by two methods:

1. Removing the HDS_DIVIDERTRACK style for the header control or using a subclassed header control that did not have this flag set.

2. Handling the HDN_ITEMCHANGING notification and returning TRUE.

Did you have done one of the above?

Also, does the cursor change when moving the mouse over the dibider area?

nothing as above two methods.and the cursor is changing bt cant drag to change..

I forgot one more handler:
When a HDN_BEGINTRACK handler exists and returns TRUE, tracking of the divider is prevented.

You may check whether the problem is specific to your list control or your application by adding another report list somewhere and see if it shows the same behaviour.

that handler also not there in code anywhere.

remaining are working fine.have to check the possibilities by comparing.
