Grid of Custom Controls??

Chris Foley

I have an application that needs an interactive editor. The editor is basically a "spreadsheet" grid that only contains colors and geometric shapes drawn by the code. I need to have events tied to each of the "cells". I have seen grid and spreadsheet classes out there but my needs are so basic that the overhead of these sheets is burdensome.

My question is, do I make each cell a custom control? I will need several hundred available at one time. During the actual editing process, speed is no real issue. But when the programs switches from edit mode to run mode, I need to be able to just display each graphic quickly in a scrolling fashion. I am concerned that creating a large number of custom controls will be a large processor issue. The screen would only show a several hundred of a total of several thousand data points.

I hope this makes sense!

Thanks

I am trying to look into this. However, it was done in 2003 and I cannot get a clean compile in 2010.

Sample Error:

Error 13 'System.Windows.Forms.AutoSizeMode' does not contain a definition for 'EnableStretch' and no extension method 'EnableStretch' accepting a first argument of type 'System.Windows.Forms.AutoSizeMode' could be found (are you missing a using directive or an assembly reference?) C:\Documents and Settings\chris.foley\My Documents\C# Examples\SourceGrid2\SourceGrid\Grids\GridVirtual.cs 480 81 SourceGrid2

SourceGrid2 is referenced and the dll is in the proper place so I am still looking for the issue.

Hi

You can refer following code for grid of custom control.

private void frmSample15_Load(object sender, System.EventArgs e)
{
  gridVirtual1.GettingCell += new SourceGrid2.PositionEventHandler(
    gridVirtual1_GettingCell);
  gridVirtual1.Redim(1000,1000);
  string[,] l_Array = new string[gridVirtual1.RowsCount, 
    gridVirtual1.ColumnsCount];
  m_CellStringArray = new CellStringArray(l_Array);
  m_CellStringArray.BindToGrid(gridVirtual1);
