HI all,

I've got a grid that uses a web service as a datasource. I've got a method in the web service to retrieve and filter data as needed.
The data retrieves and filter okay but when I select a row from the filter, client-side, then try to retrieve a value from the selected row in the filter it comes up with &nbsp& or no value. However it works if I physically click on a row when I set up a row selected event to retrieve the value.

In other words, selecting a row in javascript code doesn't work. Do I need to rebind the grid or something. I've tried many different samples/solutions and nothing seems to work.

Here's the service, Grid, and Javascript from the client.

Hello Jim,

Normally the filtering requires the grid to refresh and repopulate its data. You should not get the values of the selected items immediately after filtering because they might not be populated yet. You can try this in a later event or after the page has refreshed. You can also try the selectItem method of the MasterTableView to see if it makes a difference in your case.
