yValue

Enumerable datasource object that provides the  Y-value(s).


Enumerable objects with Y values.
yFields

Data source field(s) to bind data point(s) to. Note that a comma can be embedded as part of a column name by using a double comma.


Name of the field(s) for Y value(s).

Data binds the Y-value(s) of the data points to the specified column(s) of the specified data source.


Data bind Y values of the data points to the data source. Data source can be the Array, Collection, Ole(SQL)DataReader, DataView, DataSet, DataTable or DataRow.

Syntax

Visual Basic (Declaration)  
Public Overloads Sub DataBindY( _
   ByVal yValue As IEnumerable, _
   ByVal yFields As String _
) 
Visual Basic (Usage) Copy Code
Dim instance As DataPointCollection
Dim yValue As IEnumerable
Dim yFields As String
 
instance.DataBindY(yValue, yFields)
C#  
public void DataBindY( 
   IEnumerable yValue,
   string yFields
)

Parameters

yValue

Enumerable datasource object that provides the  Y-value(s).


Enumerable objects with Y values.
yFields

Data source field(s) to bind data point(s) to. Note that a comma can be embedded as part of a column name by using a double comma.


Name of the field(s) for Y value(s).

Remarks

This method binds the Y-values of the collection's data points to the specified fields(s) of the data source.

To bind only to the first field in a data source you can also use the DataBindY Method (IEnumerable).

You can bind to several fields by setting the yFields argument to multiple field names that are comma-separated. Note that the first field will be used for the data point's first Y-value, the second named field will be used for the data point's second Y-value, etc.

If Y-values are not provided by the datasource, or the wrong number of values are provided an exception will be thrown.

The following is a list of objects that you can use as the datasource (yValue  parameter):

  • DataView

  • Data readers (SQL, OleDB)

  • Arrays

  • Lists

  • All other objects that use the IEnumerable interface.

Requirements

Target Platforms: Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family, Windows Vista, Windows Server 2008 family
