Problem


How do I resize the client area of a grid view to fit the width or height of the grid?


Cause



Action


The following function will calculate the grid's width and height and resize the parent frame accordingly. You can call this function from your OnInitialUpdate() routine.

void C1stGridView::FitToSize()
{
UpdateFontMetrics();
CFrameWnd* pFrame = GetParentFrame();
CMDIChildWnd* pMDIChild = NULL;
CWnd* pMDIClient = NULL;
CRect oClientRect;

if (pFrame && pFrame->IsKindOf(RUNTIME_CLASS(CMDIChildWnd)))
{

pMDIChild = (CMDIChildWnd*) pFrame;
pMDIClient = pFrame->GetParent();
pMDIChild->MDIRestore();
pMDIClient->GetClientRect(&oClientRect);


int colTotalWidth = CalcSumOfColWidths(0,GetColCount(), oClientRect.Width());

int colTotalHeight = CalcSumOfRowHeights(0,GetRowCount(), oClientRect.Height());

// Check if the calculated value
// is more than the default
// client area of the grid.
if (colTotalHeight >= oClientRect.Height())

colTotalWidth += ::GetSystemMetrics(SM_CXVSCROLL);
colTotalWidth += 7*(::GetSystemMetrics(SM_CXEDGE));

if (colTotalWidth >= oClientRect.Width())

colTotalHeight += ::GetSystemMetrics( SM_CYHSCROLL);
colTotalHeight += 7*(::GetSystemMetrics(SM_CYEDGE));

// Add the window title bar to the height
colTotalHeight+=::GetSystemMetrics(SM_CYCAPTION);
colTotalHeight = min(colTotalHeight, oClientRect.Height());
colTotalWidth = min(colTotalWidth, oClientRect.Width());

pFrame->SetWindowPos(NULL, 0, 0, colTotalWidth,colTotalHeight, SWP_NOACTIVATE|SWP_NOMOVE|SWP_NOZORDER);

}
}
