C# red cross in datagridview

i am using c# and when i try to fill my datagridView most of the time a big red cross apears.

i searched for this and people say that you have to add

public class SafeDataGridView : DataGridView
{
   protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
   {
      try
      {
        base.OnPaint(e);
      }
      catch (Exception)
      {
        this.Invalidate();
      }
   }
}

i tried to just add this in a simple class file but that did not do anything.

Same question here. Use Invoke method

if (gridView.InvokeRequired)
    gridView.Invoke(new MethodInvoker(() => gridView.DataSource = YOUR_DATASOURCE));
else
    gridView.DataSource = YOUR_DATASOURCE;

In YourForm.Designer.cs look for string gridView = new DataGridView() and replace it with

gridView = new SafeDataGridView()

private SafeDataGridView portos_online;

portos_online = new SafeDataGridView();

I hope this will solve your problem. Have a nice day!
