Hi Everyone,

I want to make a cross tab report in c#.
The table columns in cross- tab report must contain two or more columns.
<img src="http://i40.tinypic.com/27ytmib.jpg" border="0" alt="Image and video hosting by TinyPic">

And these columns Column 1, Column 2, Column 3 represents the device. And we have three devices here. Like Column 1 is a device1 and on 10-08-2013 it runs for 13 hours and consume 120 liter of diesel. And the Column2 and Column3 also have their running hours and consumption details.

And the Column1, Column2 ,.... are dynamic. Means they can increase or decrease.

But the problem is that I am not able to get the functionality in Crystal report that how I manage RUN and Consumption columns under single device column in Cross-Tab.
Because to generate crystal report I am using a xsd dataset. In which I have to defined the columns. But due to increasing and decreasing in Device Columns it is hard to change the dataset.

Hope it helps to understand the question.

Thank You.
