Remarks

An item’s metadata are key-value pairs of string and object types, respectively. Use the Metadata property to specify the item’s metadata using an appropriate FileManagerFile or FileManagerFolder constructor. To access the item’s metadata, use the FileManagerItem.Metadata property.

To obtain the item’s metadata, use the following methods:

• the FileManagerItemMetadata.GetAllKeys and FileManagerItemMetadata.GetValueByKey methods (on the server side);
• the ASPxClientFileManagerItem.GetMetadata method (on the client side if the FileManagerSettings.EnableClientSideItemMetadata property is set to true).

• System.String
• System.Guid
• System.Byte
• System.Int16
• System.Int32
• System.Int64
• System.Double
• System.Boolean
• System.Single
• System.Decimal
• System.Char
• System.DateTime

new FileManagerItemProperties {
Metadata = new Dictionary<string, object>() {
{ "meta1", "value1" },
{ "meta2", "value2" }
};
});
