ColumnCount Property (RowHeader)
Example 


Gets or sets the number of columns in the row header.
Syntax
'Declaration
 
Public Property ColumnCount As Integer
'Usage
 
Dim instance As RowHeader
Dim value As Integer
 
instance.ColumnCount = value
 
value = instance.ColumnCount
public int ColumnCount {get; set;}

Property Value

Integer number of columns in the header
Exceptions
ExceptionDescription
System.ArgumentOutOfRangeException Specified column count is less than 0 or greater than 256.
Remarks

Use this property to specify the number of columns in the row header. When you set this property to a value greater than 1, additional columns are added to the row header. The maximum value allowed is 256. The minimum value allowed is 0.

This property is equivalent to the SheetView RowHeaderColumnCount.

The added columns display the row header appearance (the background, text, and border colors) but are blank by default. Use the Text property to add content to the additional columns.

If you set this property to a value greater than 1, you can specify which column displays the automatic text by setting the AutoTextIndex property. The right-most header column displays the automatic text, as defined in the AutoText property, unless another header column is specified by the AutoTextIndex property.

This property does not have an effect unless the Visible property (or the SheetView RowHeaderVisible property) is set to true and the row header columns are not hidden.

Tip: If the Spread component displays multiple header columns such that the row headers fill the entire view of the spreadsheet, users cannot scroll to the data portion of the spreadsheet. Keep this in mind when sizing the Spread component and adding multiple row header columns.

Set the ColumnHeader RowCount property (or SheetView ColumnHeaderRowCount property) to specify the number of rows to display as the column header.

For more information about headers with multiple columns or rows, see Creating a Header with Multiple Rows or Columns.

Example
This example sets the row header to have four columns and changes the background color of the first four row headers.
Dim r As FarPoint.Win.Spread.RowHeader
r = FpSpread1.ActiveSheet.RowHeader
r.ColumnCount = 4
r.Cells(0, 0, 3, 3).BackColor = Color.Teal
FarPoint.Win.Spread.RowHeader r;
r = fpSpread1.ActiveSheet.RowHeader;
r.ColumnCount = 4; 
r.Cells[0, 0, 3, 3].BackColor = Color.Teal;
