SummaryFunc Property

Gets or sets the summary function type used to process the DataField values.

Syntax

Visual Basic
C#

'Declaration
 
Public Property SummaryFunc As SummaryFunc

public SummaryFunc SummaryFunc {get; set;}

Property Value

SummaryFunc enumeration value that specifies the type of summarization to be performed on the field. Default is SummaryFunc.Sum

Remarks

You can use this function to create subtotals, grand totals and other summary values. SummaryFunc has no effect unless the SummaryType property is set to either SubTotal or GrandTotal.

Note: When a summary function is used on a control, the CanGrow and CanShrink properties will have no effect since the summary is calculated after the control height has been determined and finalized.

Example

private void detail_Format(object sender, System.EventArgs eArgs)
{
    this.TextBox1.SummaryFunc = SummaryFunc.Sum;
    this.TextBox1.SummaryGroup = null;
    this.TextBox1.SummaryRunning = SummaryRunning.None;
    this.TextBox1.SummaryType = SummaryType.None;
}

Visual Basic

Private Sub Detail1_Format(ByVal sender As Object, ByVal e As System.EventArgs) Handles Detail1.Format
   Me.TextBox1.SummaryFunc = SummaryFunc.Sum
   Me.TextBox1.SummaryGroup = Nothing
   Me.TextBox1.SummaryRunning = SummaryRunning.None
   Me.TextBox1.SummaryType = SummaryType.None
End Sub
