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

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

VB.NET

    Dim profitFormatCondition = New FormatCondition() With {
        .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.
