To access individual rows in Jquery Easy UI for making specific ajax requests, you can use the selectedIndex property of the datagrid object, which returns the index of the selected row. Once you have the index of the selected row, you can retrieve the row data by using the getData method of the datagrid object. This will return an object that represents the data for the selected row. You can then use this data to make an ajax request.

Alternatively, you can use the getRowIndex method of the datagrid object to get the row index of a specific row based on some criteria, such as the value of a particular column. Once you have the row index, you can retrieve the row data using the getData method as described above.

Here's an example code snippet that demonstrates how to access individual rows in Jquery Easy UI for making specific ajax requests:

// Get the datagrid object
var dg = $('#datagrid').datagrid({
   // your datagrid options here
});

// Attach a function to the click event of a button that makes an ajax request using the data from the selected row
$('#my-button').click(function() {
    // Get the index of the selected row
    var rowIndex = dg.datagrid('getRowIndex', $('#datagrid').datagrid('getSelected'));

    // Get the data for the selected row
    var rowData = dg.datagrid('getData').rows[rowIndex];

    // Make an ajax request using the data from the selected row
    $.ajax({
        type: 'POST',
        url: 'myUrl',
        data: {
            // use the rowData object to pass data to the server
        },
        success: function(data) {
            // handle the response from the server
        },
        error: function(jqXHR, textStatus, errorThrown) {
            // handle the error
        }
    });
});

Note that this is just an example, and you may need to adapt it to your specific use case.
