	when removing rows from a table, the flowchart control crashes with an Index out of range Exception. how to reproduce this error with the flowchart.net demo application (version 4.3.1): - select "Table-related diagrams" - select the "ERM Diagram" - click on (select) "Entity4" box - in the lefthand property window, select the "Rows" property and open the "Row Collection Editor" by clicking on "..." - remove all three members in the row collection editor - apply the changes the application now crashes with beforementioned exception. Is there a way to tell the flowchart control that the box content has changed or should the control figure this out by itself ? tnx

	Hi, At this time the control does not track changes that you do directly to the Rows or Columns collections of a table. Use them only for read access to the rows and columns. You must call the DeleteRow method to delete a row, or you could set the table's RowCount property to a smaller value. Stoyan

	tnx for the answer. If I remember correctly, when displaying the chart I can't prevent the user from deleting rows from a table. Am I right or can this be prevented ? cu Stoyo wrote on Oct 31^st, 2007 at 3:32pm: Hi, At this time the control does not track changes that you do directly to the Rows or Columns collections of a table.

	If you display the table properties in a property grid, the user will be able to delete rows by setting a smaller RowCount value. You could display only a subset of the table properties as shown in the Flowcharter sample project. Stoyan
