The reason for this is that RadChart does not support DateTime values
out of the box. However, you can use their ToOADate equivalents. You
can find an example here
. In order to use this with SqlDataSource you will need to create your query so, that it returns the OleAutomation equivalents of the date values -- this is done like this:
SELECT CAST(MyDate as FLOAT) + 2 as MyFloatDate.....
Please, find attached a sample page, showing a gantt chart databound to a SqlDataSource control. I have chosen the date columns in the Employees table in Northwind. Hope this helps.
