E1034

The current browser does not implement an API required for saving files.

The IE8, IE9 and Safari (integrated in Mac OS) browsers do not implement an API for saving files. In this instance, the dxDataGrid widget can POST the content to a server-side proxy which will stream the file back to the end user. To enable this functionality, set the export | proxyUrl option to the proxy which will stream the file to the end user. When implementing the proxy, take the following information into account.

  • Your proxy will receive a POST request with the following parameters in the request body: fileName, contentType (the MIME type of the file) and base64 (the base-64 encoded file content).
  • The proxy should return the decoded file with the "Content-Disposition" header set to attachment; filename="".

W1001

Occurs in the dxMap widget if the key option value is changed after the widget is created.

Do not change the key after the widget is created.

W1002

Occurs in a collection widget if you try to select an item that does not exist.

Check the validity of the specified item.

Occurs in the dxList widget if you try to select an item relating to a group that does not exist.

W1004

Occurs in the dxList widget if you try to select an item that does not exist within the specified group.

W1005

Occurs when data is loaded twice when applying initial filter settings.

When both a value for the Filter Row and text for the Search Panel are set for the grid, data loading will be performed twice. The first load will be performed to learn data types for grid columns, and the second one - to apply filters. To avoid double data loading, set data types for all grid columns.
