Standard Formatting Mechanism
- 2 minutes to read
Display values can be formatted using the standard formatting mechanism described in MSDN. It allows you to format values using standard format patterns. For instance, a numeric value can be represented as a currency amount, a hexadecimal value, in scientific notation, etc. A date/time value can be represented in the standard Short Date, Long Date or Full Date/Time form.
Data Cells
To format cell values using this approach, use a column editor’s EditPropertiesBase.DisplayFormatString property.
<dxwgv:GridViewDataSpinEditColumn FieldName="Budget" VisibleIndex="2">
<PropertiesSpinEdit DisplayFormatString="c2" NumberFormat="Custom">
</PropertiesSpinEdit>
</dxwgv:GridViewDataSpinEditColumn>

Summary Values
Values displayed within summary cells can be formatted using a summary item’s ASPxSummaryItemBase.DisplayFormat property.
<TotalSummary>
<dxwgv:ASPxSummaryItem DisplayFormat="Count: {0}" FieldName="ID" ShowInColumn="ID"
SummaryType="Count" />
<dxwgv:ASPxSummaryItem DisplayFormat="Max Budget = {0:c2}"
FieldName="Budget" ShowInColumn="Budget"
SummaryType="Max" />
</TotalSummary>

Group Rows
The ASPxGridViewSettings.GroupFormat property allows you specify the text pattern for group rows. The text pattern can include static text plus predefined placeholders.
By default, this property is set to “{0}: {1} {2}“. The {0} character sequence is the placeholder for the grouping column’s caption. The {1} sequence is the placeholder for the grouping column’s value, which corresponds to the current group row. Finally, the {2} character sequence is the placeholder for the group row’s summary text.
<dxwgv:ASPxGridView ID="ASPxGridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="AccessDataSource1" FilterEnabled="True" KeyFieldName="ID">
...
<Settings ShowFooter="True" ShowGroupPanel="True" GroupFormat="{1}: {2}" />
<GroupSummary>
<dxwgv:ASPxSummaryItem DisplayFormat="{0} Departments" FieldName="Department"
SummaryType="Count" />
</GroupSummary>
</dxwgv:ASPxGridView>
