Property Value

Type	Description
String	A string value that specifies the expression used to apply a conditional format.

Remarks

The XAML snippet below illustrates how to change the font color to green for positive values in the Profit column.

XAML

<dxg:GridControl.FormatConditions>
    <dxg:FormatCondition FieldName="Profit" Expression="[Profit] &gt; 0" PredefinedFormatName="GreenText"/>
</dxg:GridControl.FormatConditions>

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

C#

var profitFormatCondition = new FormatCondition() {
    FieldName = "Profit",
    Expression = "[Profit] > 0",
    PredefinedFormatName = "GreenText"
};
gridControl.FormatConditions.Add(profitFormatCondition);

The image below shows the result.

Use the ValueRule property to specify a predefined rule for conditional formatting.
