Removing Empty Tables
Removing objects from a collection during iteration causes errors. This snippet collects all-empty tables into an ArrayList in a first pass, then iterates the list to safely call Tables.Remove() for each one, setting InputPosition to the first cell of each table before calling Remove.
I thought that I would quickly share this code with you that removes all empty tables in a document.
An ArrayList is used to collect all tables in which cells are empty. This is required, because it is not possible to remove an object from a collection when iterating through this collection. Therefore, we are using two loops: The first to get the empty tables and the second loop to remove the tables from the collection.
private void removeEmptyTables()
{
ArrayList deleteTables = new ArrayList();
foreach (TXTextControl.Table curTable in textControl1.Tables)
{
deleteTables.Add(curTable);
foreach (TXTextControl.TableCell curCell in curTable.Cells)
{
if (curCell.Text != "")
{
deleteTables.Remove(curTable);
continue;
}
}
}
foreach (TXTextControl.Table delTable in deleteTables)
{
textControl1.InputPosition = new TXTextControl.InputPosition(delTable.Cells.GetItem(1, 1).Start);
textControl1.Tables.Remove();
}
