The Data Update conditional format allows you to visualize changing values in real time.

The image below shows a grid with the applied Data Update conditional formats.

To create the Data Update conditional format in code, create the DataUpdateFormatCondition class instance and specify the following settings:

Specify the data update rule that determines when date update formatting should be applied, using the DataUpdateFormatCondition.Rule property. To define a custom logic, set the DataUpdateFormatCondition.Rule property to DataUpdateRule.Custom and handle the TableView.CustomDataUpdateFormatCondition (or TreeListView.CustomDataUpdateFormatCondition) event.
Use the FormatConditionBase.FieldName property to specify the column’s field name to which to apply the conditional format.
Specify the target cells’ formatting in one of the following ways:
Add the resulting DataUpdateFormatCondition instance to the TableView.FormatConditions (or TreeListView.FormatConditions) collection.

The following code sample illustrates how to define a conditional format in markup:

XAML

xaml

<dxg:TableView.FormatConditions>
   <dxg:DataUpdateFormatCondition Rule="Increase" FieldName="Change" PredefinedFormatName="GreenFillWithDarkGreenText"/>
</dxg:TableView.FormatConditions>

The code sample below illustrates how to define the same conditional format in code-behind:

C#
VB.NET

csharp

var changeFormatCondition = new DataUpdateFormatCondition() {
   Rule = DataUpdateRule.Increase,
   FieldName = "Change",
   PredefinedFormatName = "GreenFillWithDarkGreenText"
};
view.FormatConditions.Add(changeFormatCondition);

Dim changeFormatCondition = New DataUpdateFormatCondition() With {
   .Rule = DataUpdateRule.Increase,
   .FieldName = "Change",
   .PredefinedFormatName = "GreenFillWithDarkGreenText"
}
view.FormatConditions.Add(changeFormatCondition)
