IMapTableInfo Interface

Provides access to the Table Info.

Members

	Name	Description
	DisplayField	Primary display field.
	Fields	Array of attribute fields contained in the table.
	HasAttachments	Indicates if the layer has attachments.
	HasSubtype	Indicates if the layer has Subtype.
	HTMLPopupType	Indicates if the layer has HTML popups enabled.
	ID	The table ID. This is a unique ID among layers and tables, and is used to identify the table in a number of methods.
	Name	Descriptive name of the table.
	OIDFieldName	The name of the OID Field.
	RelateInfos	Array of relates associated to the table.

IMapTableInfo.DisplayField Property

Primary display field.

Public ReadOnly Property DisplayField As String

public string DisplayField {get;}

Remarks

When DisplayExpression is used in the source map document, MapServer returns the first field used in the expression.

IMapTableInfo.Fields Property

Array of attribute fields contained in the table.

Public ReadOnly Property Fields As IFields

public IFields Fields {get;}

Remarks

Note: ObjectID field is always included even when the field is invisible in the source map document.

IMapTableInfo.HasAttachments Property

Indicates if the layer has attachments.

Public ReadOnly Property HasAttachments As Boolean

public bool HasAttachments {get;}

IMapTableInfo.HasSubtype Property

Indicates if the layer has Subtype.

Public ReadOnly Property HasSubtype As Boolean

public bool HasSubtype {get;}

Remarks

Note: in case when the subtype field name is invisible in the source map document, HasSubtype will return False even though the layer has Subtypes.

IMapTableInfo.HTMLPopupType Property

Indicates if the layer has HTML popups enabled.

Public ReadOnly Property HTMLPopupType As esriServerHTMLPopupType

public esriServerHTMLPopupType HTMLPopupType {get;}

Remarks

StandaloneTable does not support HTMLPopup

IMapTableInfo.ID Property

The table ID. This is a unique ID among layers and tables, and is used to identify the table in a number of methods.

Public ReadOnly Property ID As Integer

public int ID {get;}

IMapTableInfo.Name Property

Descriptive name of the table.

Public ReadOnly Property Name As String

public string Name {get;}

IMapTableInfo.OIDFieldName Property

The name of the OID Field.

Public ReadOnly Property OIDFieldName As String

public string OIDFieldName {get;}

IMapTableInfo.RelateInfos Property

Array of relates associated to the table.

Public ReadOnly Property RelateInfos As IRelateInfos

public IRelateInfos RelateInfos {get;}

Remarks

In order for MapServer to advertise a relationship, both source and destination layer/standalone table must be added to the source map document. For example, Layer A is related to Table B in the GeoDatabase; Layer A is added to the map while Table B is not, in this scenario, MapServer will not publicize this relationship and therefore QueryRelatedRows function cannot be used to get related row(s) for feature from Layer A.

Example: Printing a list of all relates a layer or table is participating

IRelateInfos pRIs = null; 

IRelateInfo pRI = null;

pRIs = pMTI.RelateInfos;

if (pRIs == null) 

{

    Console.WriteLine("No relationship is available"); 

    return;

}

for (int j = 0; j < pRIs.Count; j++)

{

    pRI = pRIs.get_Element(j);

    Console.WriteLine(pRI.Name + ", " + pRI.RelationshipID + ", " + pRI.RelatedTableID);

}
