Dear All,

I am working on Visual Studio 2008, .NET Framework 3.5 SP1, C#.

I have a form which contains many fields and created a crystal report to display those fields by passing them as parameter fields.

I have updated the form in order to include multiple vendors to it. However the number of vendors is not fixed and vary according to the user. For that reason I should allow the user to edit this at runtime. Based on that I included a stack panel in my form and created a user control called VendorInformation and added to it some fields, let's take as example VendorName, VendorNumber, VendorCostPrice.

At runtime, if the forms supports this implementation, one vendor subform is displayed in the stackpanel. In addition, I have added an add and remove buttons.

Everytime the add button is clicked, an additional vendor is added to the stackpanel and if the remove button is clicked the vendor will be removed.

We could have 3 vendors and remove the one in the middle not necessarily the last one.

How can I include these details in my main report at runtime?

First, I should be able to add a condition based on one field to see whether the vendors should be included or not in the report.

Second, if the user adds one additional vendor, I should be able to directly update the report when he decides to print it. He can always add a vendor at the end of the others however he can remove any vendor in the middle.

The problem also is that the usercontrol created contains the same field names, and for each new vendor, an instance of that usercontrol is created so how to set the fields in the report for the right vendor?

I would appreciate any help and detailed instructions to follow because I am late and don't know how to handle this issue. Thank you in advance!

Regards,
Lara

Thank you for the reply.
The problem is that I need to add multiple sections at runtime, each section is related to one vendor and the parameter names are the same.
Can I add a section at runtime and set the locations of the fields in it based on a condition?

Thank you again for the reply!
I was able to populate the datatable at runtime and added it to the dataset in the crystal report.
The problem is that how shall I display the fields in the section I have?
I have dropped the parameters to the section but it is displaying only the last row in my datatable!
How shall I display all the rows in my datatable in the section in my report?

I am sorry I didn't get clearly what you said.
I have added the fields in a detailed section however it is just displaying the last row.
The number of rows is specified at runtime so how shall all the data in the rows be displayed?

I added a detail section and have my datatable under Database Fields in the menu and it is filled at runtime.
How to display it in the section I created?

Yes there are 2 datatables and they are linked however they do not need to be but don't know why I wasn't able to remove the link.
They both belong to the same dataset.

How shall I fix this?
