Do you delete the row by clicking a row header and pressing the delete key?

Can you reproduce this in one of our samples, or can you post a sample with the problem?

[Christian Pogea]

bug1_4410.zip use the attached sample. select the first row, press the delete key and push the "speichern" button and then you get the exception.

When you press delete the following code gets executed:

public virtual void RemoveRecords(int first, int last)
{

	TraceUtil.TraceCurrentMethodInfoIf(Switches.Development.TraceVerbose,
		first, last);
	inRemoveRecords = true;
	try
	{
		if (List != null &&
			GridListUtil.GetAllowRemove(List))
		{

			gridModel.BeginUpdate(BeginUpdateOptions.InvalidateAndScroll);
			for (int index = last; index >=
				first; index--)
			{
				if (listManager != null)

					ListManager.RemoveAt(index);
				else

					List.RemoveAt(index);
			}
			if (this.bindToCurrencyManager)

				this.listManager_PositionChanged(ListManager, EventArgs.Empty);

			this.OnRowChanged(EventArgs.Empty);

			this.OnRecordsRemoved(EventArgs.Empty);
			gridModel.EndUpdate(true);
		}
	}
	finally
	{
		inRemoveRecords = false;
	}
}

The exception gets thrown when

ListManager.RemoveAt(index);

Is called. It is the following exception:

The reason for this exception is that the DateTimePicker is bound to the same ListManager as the grid. When the grid removes the only record by calling ListManager.Remove the ListManager resets all values for the record and notifies all controls that are bound to the ListManager. Therefore it also notifies the DateTimePicker and assign a null value to it. The DateTimePicker then throws an exception.

You can workaround the problem by making sure that one row remains in the CurrencyManager when you delete the last row.

In the bmb_PositionChanged you can check for CurrenyManager.Count = 0

private void bmb_PositionChanged(object sender, EventArgs e)
{
	CurrencyManager cm = sender as CurrencyManager;
	if (cm != null && cm.Count == 0)
	{
		this.NewSerienauftrag(0);
	}
	RefreshRadioButtons();
	BeginEnableDisable();
}
