Release memory

[Lan Mo]

Hi,
VS2003, 4.4.0.51

In your sample,
C:\Program Files\Syncfusion\Essential Studio\4.4.0.51\Windows\Grid.Grouping.Windows\Samples\PerformanceSamples\GroupingPerf\CS\GroupingPerf_2003.sln

The code releases memory used by the grid by dispose it, and recreate a new grid when next time reload.
void ResetGroupingGrid()
{
if (this.grid != null)
{
this.gridPanel.Controls.Remove(this.grid);
this.grid.Dispose();
this.grid = null;
this.table.Dispose();
this.table = null;
this.LogMemoryUsage1();
}
}



My questions is:
Is there any way to release the memory used by the grid without dispose and set it to null?
Because I have a form painted GGC at designed time. There are several buttons to reload the grid by different table data or by same table with different where condition.

Thanks,

Lan

Hi Lan,

You can try resetting the datasource of the grid and then reinitialize it instead of disposing the grid.

		void ResetGroupingGrid()
		{
			if (this.grid != null)
			{
				//this.gridPanel.Controls.Remove(this.grid);
				//this.grid.Dispose();
				//this.grid = null;
				if(this.grid.DataSource != null)
				{
					this.grid.DataSource = null;
					this.grid.DataMember = "";
					this.grid.Engine.Reset();
					this.grid.Engine.ResetTableDescriptor();
					this.grid.Engine.ResetTable();
				}
				this.table.Dispose();
				this.table = null;
				this.LogMemoryUsage();
			}
		}
