i m sure like i had, most of you are dreaming to have data-driven chart gauge, right? here you go with the steps you need to do:
1. add a form view on your visual studio page
2. bind this form with the SQL data source as usual using the sql query will bring the value you want to show on the gauge
3. edit form template using edit template option from the form view smart tag options
4. add a chart gauge into the form view
5. for the value parameter, add the following code like below for the main indicator needle
<
ChartFXGauge:Needle Style="Needle02" Value='<%# ltrim(str(Eval("field name goes here"))) %>' />6. after adding this code, your chart gauge wont show on the visual studio, but DONT WORRY, just publish your page and view.
THAT'S IT!!!
