# Highlighting Rules

Spread for ASP.NET allows you to create Highlighting rules to highlight the data that meets a specified condition.

## Content

You can use this rule to highlight data that meets one of the following conditions:

* is greater than a value
* is less than a value
* is between a high and low value
* is equal to a value
* contains a value
* is a date that occurs in a particular range
* is either unique or duplicated elsewhere in the worksheet

After you choose one of the options above, enter a value or formula against which each cell is compared. If the cell data satisfies that criteria, then the formatting is applied.
You can select a predefined highlight style or create a custom highlight style. The following rules are highlight style rules:

* [BlankConditionalFormattingRule](/spreadnet/api/latest/online-asp/FarPoint.Web.Spread/FarPoint.Web.Spread.BlankConditionalFormattingRule.html)
* [ErrorConditionalFormattingRule](/spreadnet/api/latest/online-asp/FarPoint.Web.Spread/FarPoint.Web.Spread.ErrorConditionalFormattingRule.html)
* [FormulaConditionalFormattingRule](/spreadnet/api/latest/online-asp/FarPoint.Web.Spread/FarPoint.Web.Spread.FormulaConditionalFormattingRule.html)
* [TextConditionalFormattingRule](/spreadnet/api/latest/online-asp/FarPoint.Web.Spread/FarPoint.Web.Spread.TextConditionalFormattingRule.html)
* [TimePeriodConditionalFormattingRule](/spreadnet/api/latest/online-asp/FarPoint.Web.Spread/FarPoint.Web.Spread.TimePeriodConditionalFormattingRule.html)
* [UnaryComparisonConditionalFormattingRule](/spreadnet/api/latest/online-asp/FarPoint.Web.Spread/FarPoint.Web.Spread.UnaryComparisonConditionalFormattingRule.html)
* [UniqueOrDuplicatedConditionalFormattingRule](/spreadnet/api/latest/online-asp/FarPoint.Web.Spread/FarPoint.Web.Spread.UniqueOrDuplicatedConditionalFormattingRule.html)

## Using Code

Set the properties of the rule class and then apply the formatting.

## Example

This example code creates the between values rule and uses the [SetConditionalFormatting](/spreadnet/api/latest/online-asp/FarPoint.Web.Spread/FarPoint.Web.Spread.SheetView.SetConditionalFormatting.html) method to apply the rule.

```csharp
protected void Page_Load(object sender, System.EventArgs e)
{
    FpSpread1.Sheets[0].Cells[0, 0].Value = 3;
    FpSpread1.Sheets[0].Cells[1, 0].Value = 2;
    FpSpread1.Sheets[0].Cells[1, 1].Value = 5;
    FpSpread1.Sheets[0].Cells[0, 2].Value = 1;
}

protected void Button1_Click(object sender, EventArgs e)
{
    FarPoint.Web.Spread.BetweenValuesConditionalFormattingRule between = new FarPoint.Web.Spread.BetweenValuesConditionalFormattingRule(false);
    between.FirstValue = 10;
    between.SecondValue = 20;
    between.IsNotBetween = true;
    between.BackColor = Color.Bisque;
    FpSpread1.ActiveSheetView.SetConditionalFormatting(1, 1, between);
}
```

```vbnet
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    FpSpread1.Sheets(0).Cells(0, 0).Value = 3
    FpSpread1.Sheets(0).Cells(1, 0).Value = 2
    FpSpread1.Sheets(0).Cells(1, 1).Value = 5
    FpSpread1.Sheets(0).Cells(0, 2).Value = 1
End Sub

Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Dim between As New FarPoint.Web.Spread.BetweenValuesConditionalFormattingRule(False)
    between.FirstValue = 10
    between.SecondValue = 20
    between.IsNotBetween = True
    between.BackColor = Drawing.Color.Bisque
    FpSpread1.ActiveSheetView.SetConditionalFormatting(1, 1, between)
End Sub
```

## Using the Spread Designer

1. In the work area, select the cell or cells for which you want to set the conditional format.
2. Under the **Home** menu, select the **Conditional Formatting** icon in the **Style** section, then select the **Highlight Cells Rules** option, and then choose the condition.
3. From the **File** menu choose **Apply and Exit** to apply your changes to the component and exit Spread Designer.
