Dear Support,

I need to prevent the user from changing the height of CExtPropertyGridCtrl rows.

Thanks,
Ron.

The property grid control contains two tree grid windows initialized by default: categorized property tree and sorted property tree. Both cannot be resized by default. We can guess you have custom trees in the property grid. If it is the case, could we take a look at the code that initializes these tree grids?

My mistake - I meant width.

The CExtPropertyGridCtrl control is a container for one or more tree grid windows. By default, there are two tree grids in it: CExtPropertyGridWndCategorized and CExtPropertyGridWndSorted. So you should get pointers to these grids and change their settings:

void EnablePropertyGridColumnResizing( CExtProperyGridCtrl * pPGC, bool bEnable = true )
{
CTypedPtrArray < CPtrArray, CExtPropertyGridWnd * > arrGrids;
    pPGC->OnPgcQueryGrids( arrGrids );
DWORD dwStylesAdd = bEnable ? (__EGBS_RESIZING_CELLS_INNER_H|__EGBS_DYNAMIC_RESIZING_H) : 0;
DWORD dwStylesRemove = bEnable ? 0 : (__EGBS_RESIZING_CELLS_INNER_H|__EGBS_DYNAMIC_RESIZING_H);
INT nGridIdx = 0, nGridCount = arrGrids.GetSize();
    for( ; nGridIdx < nGridCount; nGridIdx ++ )
    {
        CExtPropertyGridWnd * pGrid = arrGrids[ nGridIdx ];
        ASSERT_VALID( pGrid );
        pGrid->SiwModifyStyle(
            dwStylesAdd,
            dwStylesRemove
            );
    }
}
