    <p>I sort using column name to set any sorting specifics that may need to be handled based on data type stored in the column and or if the column has already been sorted on(asc/desc). Here's a snippet from my ColumnClick event handler. </p> <pre><code>private void listView_ColumnClick(object sender, ColumnClickEventArgs e) { ListViewItemComparer sorter = GetListViewSorter(e.Column); listView.ListViewItemSorter = sorter; listView.Sort(); } private ListViewItemComparer GetListViewSorter(int columnIndex) { ListViewItemComparer sorter = (ListViewItemComparer)listView.ListViewItemSorter; if (sorter == null) { sorter = new ListViewItemComparer(); } sorter.ColumnIndex = columnIndex; string columnName = packagedEstimateListView.Columns[columnIndex].Name; switch (columnName) { case ApplicationModel.DisplayColumns.DateCreated: case ApplicationModel.DisplayColumns.DateUpdated: sorter.ColumnType = ColumnDataType.DateTime; break; case ApplicationModel.DisplayColumns.NetTotal: case ApplicationModel.DisplayColumns.GrossTotal: sorter.ColumnType = ColumnDataType.Decimal; break; default: sorter.ColumnType = ColumnDataType.String; break; } if (sorter.SortDirection == SortOrder.Ascending) { sorter.SortDirection = SortOrder.Descending; } else { sorter.SortDirection = SortOrder.Ascending; } return sorter; } </code></pre> <p>Below is my ListViewItemComparer</p> <pre><code>public class ListViewItemComparer : IComparer { private int _columnIndex; public int ColumnIndex { get { return _columnIndex; } set { _columnIndex = value; } } private SortOrder _sortDirection; public SortOrder SortDirection { get { return _sortDirection; } set { _sortDirection = value; } } private ColumnDataType _columnType; public ColumnDataType ColumnType { get { return _columnType; } set { _columnType = value; } } public ListViewItemComparer() { _sortDirection = SortOrder.None; } public int Compare(object x, object y) { ListViewItem lviX = x as ListViewItem; ListViewItem lviY = y as ListViewItem; int result; if (lviX == null &amp;&amp; lviY == null) { result = 0; } else if (lviX == null) { result = -1; } else if (lviY == null) { result = 1; } switch (ColumnType) { case ColumnDataType.DateTime: DateTime xDt = DataParseUtility.ParseDate(lviX.SubItems[ColumnIndex].Text); DateTime yDt = DataParseUtility.ParseDate(lviY.SubItems[ColumnIndex].Text); result = DateTime.Compare(xDt, yDt); break; case ColumnDataType.Decimal: Decimal xD = DataParseUtility.ParseDecimal(lviX.SubItems[ColumnIndex].Text.Replace("$", string.Empty).Replace(",", string.Empty)); Decimal yD = DataParseUtility.ParseDecimal(lviY.SubItems[ColumnIndex].Text.Replace("$", string.Empty).Replace(",", string.Empty)); result = Decimal.Compare(xD, yD); break; case ColumnDataType.Short: short xShort = DataParseUtility.ParseShort(lviX.SubItems[ColumnIndex].Text); short yShort = DataParseUtility.ParseShort(lviY.SubItems[ColumnIndex].Text); result = xShort.CompareTo(yShort); break; case ColumnDataType.Int: int xInt = DataParseUtility.ParseInt(lviX.SubItems[ColumnIndex].Text); int yInt = DataParseUtility.ParseInt(lviY.SubItems[ColumnIndex].Text); return xInt.CompareTo(yInt); break; case ColumnDataType.Long: long xLong = DataParseUtility.ParseLong(lviX.SubItems[ColumnIndex].Text); long yLong = DataParseUtility.ParseLong(lviY.SubItems[ColumnIndex].Text); return xLong.CompareTo(yLong); break; default: result = string.Compare( lviX.SubItems[ColumnIndex].Text, lviY.SubItems[ColumnIndex].Text, false); break; } if (SortDirection == SortOrder.Descending) { return -result; } else { return result; } } } </code></pre>

    2. COWhen creating your ListViewitemComparer based on the link that I provided above you will need to add this code to get Ascending/Descending sorting: string itemXText = itemX.SubItems[Column].Text; string itemYText = itemY.SubItems[Column].Text; //sorting if (itemX.ListView.Sorting == SortOrder.Ascending) { return String.Compare(itemXText, itemYText); } else { return String.Compare(itemYText, itemXText); }

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
