Property Value

Boolean: true if marked as locked; false otherwise

You can specify that certain columns of cells are locked; that is, the user cannot edit them. You mark columns of cells as locked by setting this property to true. Columns of cells are not locked until the SheetView Protect property is also set to true for the sheet. Because the default value of the Protect property is true, unless you have changed the value of the Protect property, when you mark a column of cells as locked, they are locked and the user cannot edit them. When the Protect property is false, the user can still interact with cells marked as locked.

Be aware that the setting for this property can be overridden if a named style is assigned to the cell using the StyleName property, and that named style sets the locked status.

This example locks the cells in the column so they cannot be edited when the Protect property is set to True.

C#

FarPoint.Win.Spread.Column col;
int i, j;
col = fpSpread1.ActiveSheet.Columns[0, 2];
col.Locked = true;
for (i = 0; i <= col.Index2; i++)
{
      for (j = 0; j <= fpSpread1.ActiveSheet.RowCount - 1; j++)
            fpSpread1.ActiveSheet.Cells[j, i].Text = "Locked";
}

Visual Basic

Dim col As FarPoint.Win.Spread.Column
Dim i, j As Integer
col = fpSpread1.ActiveSheet.Columns(0, 2)
col.Locked = True
For i = 0 To col.Index2
      For j = 0 To fpSpread1.ActiveSheet.RowCount - 1
            fpSpread1.ActiveSheet.Cells(j, i).Text = "Locked"
      Next j
Next i
