<div class="markdown level1 remarks"><p>The <a class="xref" href="C1.Win.TrueDBGrid.C1DataColumn.EditMask.html#C1_Win_TrueDBGrid_C1DataColumn_EditMask">EditMask</a> property allows an input mask to be specified for automatic input formatting and validation. The mask syntax is similar to the one used by Microsoft Access. Setting the input mask for a column will prevent the user from entering any information in the cell that is not in the format of the <a class="xref" href="C1.Win.TrueDBGrid.C1DataColumn.EditMask.html#C1_Win_TrueDBGrid_C1DataColumn_EditMask">EditMask</a> string.</p>
