{parameters}
{param:arrayData}A rectangular array of objects to use as the data source. By default, the first dimension corresponds to row and the second to column \(that is, Object\[row,column\]\).{param}
{param:columnNames}The names of the columns to get from the data source. If the {{columnNames}} parameter is null, field binding can only be performed by ordinal \(for example, \%\%=DSN.\#1 or \%\%=$DSN\). If {{columnNames}} is specified, both ordinal field binding and named field binding can be used.{param}

{param:dataSourceName}The name of the set of data markers at which to insert the values imported from the data source. {{dataSourceName}} must be specified, but can be left as null or an empty string if this is the first data source bound AND the data markers in the template use the [short data marker syntax|http://wiki.softartisans.com/display/EW8/Creating+Data+Markers#CreatingDataMarkers-short] or refer to the datasource by number rather than name. Note: {{dataSourceName}} does not include a data marker's column name, for example, the {{dataSourceName}} for {{%%=Products.ProductID}} is "Products."{param}
{param:property}The [DataBindingProperties|DataBindingProperties] object which contains information about how the data should be bound to the template.
{param}

{param:property}The [DataBindingProperties|DataBindingProperties] object which contains information about how the data should be bound to the template.  {{property}} Must be specified, but the {{DataBindingProperties}} need not be set beforehand.  To bind data to a template with the default {{DataBindingProperties}}, pass in {{ExcelTemplate.CreateDataBindingProperties()}} as the {{property}} value.  Otherwise, use the {{ExcelTemplate.CreateDataBindingProperties()}} method to generate a new {{DataBindingProperties}} object and set the [DataBindingProperties.MaxRows|DataBindingProperties.MaxRows], [DataBindingProperties.Transpose|DataBindingProperties.Transpose], and/or [DataBindingProperties.WorksheetName|DataBindingProperties.WorksheetName] properties for the workbook.{param}
{exceptions}
{exception:ArgumentNullException}{{BindData}} will throw this exception if {{null}} \(C\#\) or {{Nothing}} \(VB.NET\) is passed to the method.{exception}
{exception:ArgumentException}{exception}
{exception:SARuntimeException}{{BindData}} will throw this exception if the data source contains more rows than the worksheet can hold.
 If there is more than one data marker referring to a data source and the data source is forward only, the exception will be thrown only if the source is larger than all bindings can hold.

{exception}
{remarks}You can set several data sources for a single template. Use the following methods to set template data sources: [BindCellData|ExcelTemplate.BindCellData(Object, String, DataBindingProperties)], [BindColumnData|ExcelTemplate.BindColumnData], [BindRowData|ExcelTemplate.BindRowData], and [BindData|ExcelTemplate.BindData].

Parameters
Param
arrayData
arrayData

A rectangular array of objects to use as the data source. By default, the first dimension corresponds to row and the second to column (that is, Object[row,column]).

Param
columnNames
columnNames

The names of the columns to get from the data source. If the columnNames parameter is null, field binding can only be performed by ordinal (for example, %%=DSN.#1 or %%=$DSN). If columnNames is specified, both ordinal field binding and named field binding can be used.

Param
dataSourceName
dataSourceName

The name of the set of data markers at which to insert the values imported from the data source. dataSourceName must be specified, but can be left as null or an empty string if this is the first data source bound AND the data markers in the template use the short data marker syntax or refer to the datasource by number rather than name. Note: dataSourceName does not include a data marker's column name, for example, the dataSourceName for %%=Products.ProductID is "Products."

Param
property
property

The DataBindingProperties object which contains information about how the data should be bound to the template.

Param
property
property

The DataBindingProperties object which contains information about how the data should be bound to the template. property Must be specified, but the DataBindingProperties need not be set beforehand. To bind data to a template with the default DataBindingProperties, pass in ExcelTemplate.CreateDataBindingProperties() as the property value. Otherwise, use the ExcelTemplate.CreateDataBindingProperties() method to generate a new DataBindingProperties object and set the DataBindingProperties.MaxRows, DataBindingProperties.Transpose, and/or DataBindingProperties.WorksheetName properties for the workbook.

Exceptions
Exception
ArgumentNullException
ArgumentNullException

BindData will throw this exception if null (C#) or Nothing (VB.NET) is passed to the method.

Exception
ArgumentException
ArgumentException

Exception
SARuntimeException
SARuntimeException

BindData will throw this exception if the data source contains more rows than the worksheet can hold.
If there is more than one data marker referring to a data source and the data source is forward only, the exception will be thrown only if the source is larger than all bindings can hold.

Remarks

You can set several data sources for a single template. Use the following methods to set template data sources: BindCellData, BindColumnData, BindRowData, and BindData.
