Syntax

Visual Basic
C#

'Declaration
 
Public ReadOnly Property NonEmptyColumnCount As Integer

'Usage
 
Dim instance As SheetView
Dim value As Integer
 
value = instance.NonEmptyColumnCount

public int NonEmptyColumnCount {get;}

Property Value

Integer number of columns that have data

Remarks

This property is dependent on the data model for the sheet (Models.Data) implementing the INonEmptyCells interface. If this interface is not implemented on the selection model, then this property returns -1.

This property is available at run time only.

Example

This example illustrates the use of this member by returning a value that is one more than the index of the last column and row containing data.

Random r = new Random();
int countc, countr;
int i, j;
for (i = 0; i<=50; i++)
{
    for (j = 0; j<=3; j++)
        fpSpread1.ActiveSheet.SetValue(i, j, r.Next(1, 200).ToString());
}
countc = fpSpread1.ActiveSheet.NonEmptyColumnCount;
countr = fpSpread1.ActiveSheet.NonEmptyRowCount;
label1.Text = "The number of the first non-empty column is " + countc.ToString() + " and the number of the first non-empty
row is " + countr.ToString();

Visual Basic

Dim r As New Random()
Dim i, j, x As Integer
Dim countc, countr As Integer
For i = 0 To 50
    For j = 0 To 3
        FpSpread1.ActiveSheet.SetValue(i, j, r.Next(1, 200).ToString())
    Next j
Next i
countc = FpSpread1.ActiveSheet.NonEmptyColumnCount
countr = FpSpread1.ActiveSheet.NonEmptyRowCount
Label1.Text = "The number of the first non-empty column is " & countc.ToString() & " and the number of the first non-empty
row is " & countr.ToString()
