MinValue Property

Specifies the minimum value that can be entered in the cell. Default value is null meaning no minimum constraint. The object assigned to this property should be the same type as the column's DataType or compatible otherwise it won't be honored.

Syntax

Visual Basic

'Declaration
 
Public Property MinValue As Object

C#

public object MinValue {get; set;}

Example

The following code shows how to set min and max constraints on a column. When the user attempts to exit the edit mode (for example by leaving the cell) after entering a value that doesn't satisfy MinValue or MaxValue constraint, the grid fires CellDataError event and shows an error message. You can show you own message by hooking into CellDataError. MinValue and MaxValue are object types, so you can assign a min value and max value for different column types.

Visual Basic

Imports Infragistics.Shared
Imports Infragistics.Win
Imports Infragistics.Win.UltraWinGrid

  Private Sub Button19_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles button19.Click

      Dim dateColumn As UltraGridColumn = Me.ultraGrid1.DisplayLayout.Bands(1).Columns("OrderDate")
      Dim numericColumn As UltraGridColumn = Me.ultraGrid1.DisplayLayout.Bands(2).Columns("Unit Price")

      ' Put min and max constraints on a date column.
      dateColumn.MinValue = New DateTime(1990, 1, 1)
      dateColumn.MaxValue = New DateTime(2010, 12, 31)

      ' Put a min value constraint on a numeric column.
      numericColumn.MinValue = 0.0

  End Sub
