The DevExpress dashboard is already connected to the SalesPerson view of the Northwind database. The Grid dashboard item is bound to the Sales Person and Extended Price fields. Note that the Sales Person column is sorted by the values of the Extended Price column in descending order.
Suppose that you want to format Extended Price cells whose values exceed the predefined parameter value. To do this, perform the following steps.
To create a dashboard parameter, click the Parameters button in the Home ribbon tab.
In the invoked dialog, click Add to create a new parameter...
...and specify its settings in the following way.
Click OK to create the dashboard parameter.
This invokes the Expression dialog.
Make sure that the Extended Price measure is selected in a created condition. Then, select the Is greater than criteria operator from the list.
Click the button next to the <enter a value> operand value, then click the button. The discountValue will be selected as an operand value (note that the icon will be displayed next to the selected parameter).
Finally, select the Pale Green color in the Appearance tab and click OK.
Extended Price cells corresponding to values more than the default parameter value (150000) will be filled with a pale green color.
Specify a new value (200000) in the Value column and click the Submit button. Extended Price cells corresponding to values more than 200000 will be filled with a pale green.
