CalcEdit - WinForms Calc Editor, DevExpress

Run Demo: CalcEdit

The following code snippet creates a CalcEdit control with the specified value:

C#
VB.NET

using DevExpress.XtraEditors;

CalcEdit calcEdit = new CalcEdit() {
    Location = new System.Drawing.Point(12, 12),
    Value = 100.5m
};

this.Controls.Add(calcEdit);

Imports DevExpress.XtraEditors

Dim calcEdit As New CalcEdit() With {
    .Location = New System.Drawing.Point(12, 12),
    .Value = 100.5D
}

Me.Controls.Add(calcEdit)

Edit Value

Use the Value property to specify a decimal value:

C#
VB.NET

calcEdit1.Value = 42.5m;
decimal result = calcEdit1.Value;

CalcEdit1.Value = 42.5D
Dim result As Decimal = CalcEdit1.Value

Use the EditValue property to work with a value of any type. The editor converts EditValue to decimal when the drop-down calendar opens or when the editor is validated.

Handle the ValueChanged event to respond to value changes.

Validation Behavior

When users move focus to another control or press Enter (if ValidateOnEnterKey is true), the editor converts the value to decimal. If the conversion fails, EditValue is set to 0.

Customize CalcEdit Settings

Use the Properties property to access and customize editor settings.
