Set or change current row

Each data set maintains the notion of a current row. By default, the current row is set to the first row in the data set. To change the current row programmatically, call the setCurrentRowNumber() method and pass the row number of the row you want to make the current row. The index of the first row is always zero, so if a data set contains 10 rows, the index of the last row is 9.

Use setCurrentRowByNumber() or setCurrentRow() to change the current row:

var dsPhotos = new Spry.Data.XMLDataSet("/photos.php?galleryid=2000", "/gallery/photos/photo");
...
dsPhotos.setCurrentRowNumber(2); // Make the 3rd row in the data set the current row.

Each row in the data set is also assigned a unique ID that allows you to refer to a specific row in the data set even after the order of the rows in the data set change. You can get the ID of a row by accessing its "ds_RowID" property. You can also change the current row by calling setCurrentRow() and passing the row ID of the row to make the current row.

var dsPhotos = new Spry.Data.XMLDataSet("/photos.php?galleryid=2000", "/gallery/photos/photo");
...
var id = dsPhotos.getData()[2]["ds_RowID"]; // Get the ID of the 3rd row.
...
dsPhotos.setCurrentRow(id); // Make the 3rd row the current row by using its ID.
