How to: Highlight Column Values that Match a Condition
- 2 minutes to read
This example illustrates how to apply conditional formatting to a Market Share column in a GridControl to highlight cells that match a specific condition. Cells containing values that are less than 20% will be highlighted.
- Create a new FormatCondition class instance.
- Set this object's FormatConditionBase.FieldName property to MarketShare. This column provides values to test against the formatting rule and the specified format will be applied to this column.
- Assign one of the predefined formats to the FormatConditionBase.PredefinedFormatName property. All available format names are listed in the Predefined Format Names document.
- Specify the comparison operator by setting the FormatCondition.ValueRule property. In this example, the Less operator is used for constructing the rule's criteria.
- Set the FormatCondition.Value1 property to 0.20. This means that the format should be applied to cells with market share less than 20%.
- To apply a conditional formatting rule represented by the created FormatCondition object, add this object to the GridControl.FormatConditions collection.
using DevExpress.Mobile.DataGrid; using DevExpress.Mobile.Core.ConditionalFormatting; // ... FormatCondition condition = new FormatCondition (); condition.FieldName = "MarketShare"; condition.PredefinedFormatName = "RedText"; condition.ValueRule = ConditionRule.Less; condition.Value1 = 0.20; grid.FormatConditions.Add (condition);
