In the sample project, I want to be able to pass the selected value from the comboBox SelectedIndexChanged event to a method in the code behind.
This method will use the parameter passed to fetch the amount from a database and return it to the Amount column. There is a condition that when the selected value is "Tax" then the value for amount is set to 99. This value 99 is hard-coded and I don't want that. I want it to be fetched from a database.
Currently the a value is returned using custom jsproperties but everything is hard-coded. I want to be able to pass a parameter and use it to fetch the some data from the server and pass it back to another column which is the Amount column.
Hope my explanation is clear.
