Atlas Client Script Figure 10-10 Sys.Data.DataTable The Sys.Data.DataTable class provides all information for integration with the System.Data .DataTable. The DataTable exposes the following members that may be of interest. Members get_columns() get_keys() get_isDirty() get_length() add() clear() getChanges() getColumn() getItem() remove() dispose() Description This method will return an array of DataColumns within the DataTable. This method will return an array of DataColumns that contain various keys within the DataTable. This method will return a boolean indicating whether or not updates have been made on the DataTable object. This method will return the number of rows within the DataTable. The add method will allow the addition of a DataRow. The clear() method will clear the contents of the DataTable. The getChanges() method will provide a set of DataRows that have changed. The getColumn() method will provide the specified column. The getItem() method will provide the specified row. This method is very important. The remove() will remove the specified row. Performs the standard dispose mechanism. 271
Chapter 10 The following is some code that will iterate through the rows of a DataTable: function MethodReturn(result) { var i = 0; var str = “”; var strRowsInfo = “”; var strReturn = “”; //get a datatable var tbl1 = result.getItem(0); for(i = 0; i < tbl1.get_length(); i++) { //tbl1.getItem(i) will return the ith DataRow //getProperty(“Column Name”) will return the column value from a DataRow strRowsInfo += tbl1.getItem(i).getProperty(“ProjectName”) + strReturn; } document.getElementById(“RowInfo”).innerHTML = strRowsInfo; } In the preceding code, a dataset is returned. The first datatable is obtained by the call to getItem(0). Then the DataRows are iterated. This is done by the for() loop. To get at the value of a column in a specific row, we use the getProperty(“ProjectName”) method. This method returns the value from the column ProjectName in the example. Some example output from the preceding code is shown in Figure 10-11. Figure 10-11 Sys.Data.DataRow The Sys.Data.DataRow class is the Atlas version of the System.Data.DataRow class. The DataRow has a set of properties and is designed for accessing a single row of data from a data table. For example, the DataRow.getProperty(“ColumnName”) method shown in the previous code will return the value of that specific column in that DataRow. 272
