</code></pre>
<p>Invalid information in the column layout string is ignored.</p>
<p>This property can be used to persist column layouts defined by users so they
are preserved across sessions, and it can also be used to implement undo/redo
functionality in applications that allow users to modify the column layout.</p>
<p>In order for the <a class="xref" href="C1.WPF.FlexGrid.C1FlexGrid.ColumnLayout.html#C1_WPF_FlexGrid_C1FlexGrid_ColumnLayout">ColumnLayout</a> property to work correctly, columns
should have unique names (see <a class="xref" href="C1.WPF.FlexGrid.Column.ColumnName.html#C1_WPF_FlexGrid_Column_ColumnName">ColumnName</a> property) or binding paths.</p>
