<%@ Register tagprefix= "SharePoint" assembly= "Microsoft.SharePoint, version=14.0.0.0, Culture=neutral, publickeytoken=71e9bce111e9429c "namespace=" Microsoft.SharePoint.WebControls "%>

<%@ Register assembly= "Ewebeditorcontrol" namespace= "Ewebeditorcontrol" tagprefix= "Ewebeditorcontrol"%>

<sharepoint:renderingtemplate id= "egewebeditorctrl_renderingtemplate" runat= "Server" >

<Template>

<ewebeditorcontrol:ewebeditor id= "EWebEditor1" runat= "Server" basepath= "ewebeditor/" >

public class Egewebeditorfieldtype:spfieldmultilinetext

{

#region//Construction

Public Egewebeditorfieldtype (Spfieldcollection, String fieldName)

: Base (Fields, FieldName)

{

}

Public Egewebeditorfieldtype (spfieldcollection fields, String typeName, String displayName)

: Base (Fields, TypeName, DisplayName)

{

}

#endregion

#region//Construction controls

<summary>

Constructing controls

</summary>

public override Basefieldcontrol Fieldrenderingcontrol

{

[SharePointPermission (SecurityAction.LinkDemand, ObjectModel = True)]

Get

{

Basefieldcontrol FieldControl = new Egewebeditorfieldtypecontrol ();

Fieldcontrol.fieldname = this. InternalName;

return FieldControl;

}

}

#endregion

}

}

5. inherit Basefieldcontrol, such as:

Code section:

Namespace TCL. Ep. Extendfield

{

public class Egewebeditorfieldtype:spfieldmultilinetext

{

#region//Construction

Public Egewebeditorfieldtype (Spfieldcollection, String fieldName)

: Base (Fields, FieldName)

{

}

Public Egewebeditorfieldtype (spfieldcollection fields, String typeName, String displayName)

: Base (Fields, TypeName, DisplayName)

{

}

#endregion

#region//Construction controls

<summary>

Constructing controls

</summary>

public override Basefieldcontrol Fieldrenderingcontrol

{

[SharePointPermission (SecurityAction.LinkDemand, ObjectModel = True)]

Get

{

Basefieldcontrol FieldControl = new Egewebeditorfieldtypecontrol ();

Fieldcontrol.fieldname = this. InternalName;

return FieldControl;

}

}

#endregion

}

}
