I am developing application in C# Windows Forms, i make crystal reports on the basis of data collection list in c#, for example i have a table having EmpID, Name, Sponsor, Job Title, Nationality etc. I bring them in collection in c# and pass it to crystal report, where i see my attributes in Database fields, if i drag and drop those fields on the report, for example Name, Job Title, Nationality, then i can see their columns coming in Details section, but the issue is, i have about 25 attributes and i have made a check list of 25 attributes in c#, if i check 13 attributes, it should make a report of 13 columns, the problem is, we make report in crystal report on the basis of drag and dropping fields, how can i dynamically do this, means if there are 13 fields selected in c# check list, there should be just 13 columns in report. Please find the image attached, “How currently i am doing” Please zoom it by right click on it, and open in new window.

I think that the easiest way to approach this, considering data type representations and all of the Crystal complexity under the covers, is to layout your report with all 25 fields sized appropriately.
Then, at runtime, you will need to reposition the report objects, which could be a little tricky due to the relatively unstructured way in which crystal provides the information.
The way I would approach this is to loop through the report objects and generate one SortedList for the data fields and one SortedList for the header fields. They should be sorted on their Left position so that you can process them in appearance order.
Once you have the sorted lists of objects, you can cycle through each one and, if it was not selected by the user, set the Width to 0.
As you are moving through the fields, you will keep track of the current left position. The first field that you process will set your starting point, even if it is not visible. Then, for all subsequent fields, if the field is visible, you will set its left value to the current left position, then add its width plus some separator space to the current left position for the next field.
Hopefully this will help you solve your problem.
