The Grid Control

By , , , , 5 Jun 2000
 

Introduction

After pushing the CListCtrl to its limits in trying to display and edit tabulated data I decided what was really needed was a dedicated grid control. I started writing my own grid control from scratch but decided to save time by modifying Joe Willcoxson's free WorldCom grid control. I tore apert his code and rebuilt it from the ground up in order to get it to do all the things I needed. The code has gone through so many modifications that I'm not sure if there is even a single original line of code. In any case Joe's code was a great framework on which to build.

Since the initial release at the beginning of 1998 there have been many, many versions of the grid - some better than others. There have also been ports to CE, an ATL version, and extensions that include a tree-list control.

The list of all those who have contributed and provided fixes, bug reports and suggestions is too huge to mention - thanks everyone!

Chris is the Co-founder, Administrator, Architect, Chief Editor and Shameless Hack who wrote and runs The Code Project. He's been programming since 1988 while pretending to be, in various guises, an astrophysicist, mathematician, physicist, hydrologist, geomorphologist, defence intelligence researcher and then, when all that got a bit rough on the nerves, a web developer. He is a Microsoft Visual C++ MVP both globally and for Canada locally.
 
His programming experience includes C/C++, C#, SQL, MFC, ASP, ASP.NET, and far, far too much FORTRAN. He has worked on PocketPCs, AIX mainframes, Sun workstations, and a CRAY YMP C90 behemoth but finds notebooks take up less desk space.
 
He dodges, he weaves, and he never gets enough sleep. He is kind to small animals.
 
Chris was born and bred in Australia but splits his time between Toronto and Melbourne, depending on the weather. For relaxation he is into road cycling, snowboarding, rock climbing, and storm chasing.

QuestionBug fix for frozen columnsmemberDavid Pritchard13 Sep '11 - 4:58 
Hi all,
 
Not sure if someone already mentioned this (or if it's fixed in a more recent version of the code than the one I have), but there's a bug in the painting of vertical column lines when the first non-fixed column is hidden (width 0).
 
In CGridCtrl::OnDraw(CDC* pDC), in the section that draws the lines, look for:
 
	 // draw vertical lines (drawn at ends of cells)
	 if (m_nGridLines == GVL_BOTH || m_nGridLines == GVL_VERT)
	 {
		.
		.
		.
		// LUC - frozen col stuff
		if(col == (m_nFixedCols + m_nFreezedCols))
 
 
Change this last line to:
 
		// DP 13/09/2011: Fix - this fails when the first non-fixed column is invisible - 
		// we skip past it in the previous line, and the column never gets shifted to  
		// minVisibleCol
		if(col >= (m_nFixedCols + m_nFreezedCols) && col < minVisibleCol)
 
- Pfft. Coddled kids. In my day, we used to telnet to port 80, then render the page with pencil and paper-- and that's the way we liked it!
- Pshaw! Youngster. Your UID barely fits inside 16 bits. In _my_ day we had to whistle the 1's and 0's through an acoustic coupler!
 
Tools that support "all of UTF-8 as long as it starts with ASCII" and tools that cannot handle these three [BOM] bytes at all are not really supporting UTF-8.

Sorry, forgot to mention that the error happens when you scroll to the right. That's when the painting gets screwed up.

GeneralNumbers onlymemberMember 2608808 May '11 - 7:44 
I may be blind.. looking at code for too long. But, how do I limit data entry to just numbers (no alpha, etc)? And how about just limiting to a dollar value? I.e. 10.45?

Message:- Any one can tell me how to remove flickering occurring in my grid view.
 
Problem is that I am fetching some data and refreshing it directly into my grid but when it populate data then, due to refreshing it, it is flickering in the grid view.
