Adding Rules in Code

Create the TopBottomRuleFormatCondition class instance and specify the following settings to create a conditional format in code:

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

<dxg:TableView.FormatConditions>
   <dxg:TopBottomRuleFormatCondition Rule="AboveAverage" FieldName="Profit" PredefinedFormatName="LightRedFillWithDarkRedText" />
</dxg:TableView.FormatConditions>

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

var profitFormatCondition = new TopBottomRuleFormatCondition() {
   Rule = TopBottomRule.AboveAverage,
   FieldName = "Profit", 
   PredefinedFormatName = "LightRedFillWithDarkRedText"
};
view.FormatConditions.Add(profitFormatCondition);

Adding Rules Using Conditional Formatting Menu

  1. Select the Top/Bottom Rules item in the Conditional Formatting Menu, and choose the required conditional format in the invoked sub menu.
  2. Choose a format to define the applied rule's visual appearance. The conditional formatting menu allows you to use only predefined formats stored in the TableView.PredefinedFormats (or TreeListView.PredefinedFormats) collection.
  3. Enable the apply format to the entire row option to apply a conditional format to the entire row, if necessary.
