Hello All;
I have got a task regarding parameter passing to Crystal Report via Crystal Report, I would like to find best way to achieve it.
Imagine that I have got parameterized and non reports-parameterized. I am developing a report manager that will enable users to subscribe to the reports and schedule them with their parameters. I have got a subscription web page with the list of reports. When a user wants to subscribe to a report and schedule it, if there is no parameter in the report, it is fine but if there is any parameter that needs to be passed to the report(which we can find from rpt file), user should be able to enter these parameters values via a panel in the page. and I will save those parameters' values to the database.
Effectively, I need to create a parameter entry panel to get the parameters and save them to the database with their type, value and so on, then I need to use these parameters programmatically for exporting reports to the different file formats.
Basically, I must develop parameter entry panel run time in accordance with the parameter types that the corresponding report has.
Does anyone have any idea what the best way is to achieve it?
Thanks for your help from now on and please ask for further clarification if needed/
Kind Regards.

Of course by code. Just generate the Dynamic Html from your code to get values for your parameters.
This is no big deal.
If you create an object of Textbox and render it to the client, it will be added to the page. Even you can create custom html using StringBuilder and paste any container control to produce the same output.
Dont worry about all these, just start your coding. You will definitely find the wayout yourself.
Cheers.

Dear Abhishek
Thanks for your reply, I appreciated really.
But the problem is I could not figure out, if the parameters are primitive types, this is fine I can use the way you have told.
I there any way to get list of the parameter values of a parameter of a report via code behind? Why I need to do is that, for instance, let's say reports need EmployeeID for generating report, then I will have to create a dynamic dropdown list and populated with the employees. So, that would be good if there is any way to get possible values of a parameter via c#. or will I have to do it statically?
What would you think about it? thanks for your help.
Cheers.

I think you need to somewhat figure out what are the parameters that it should be passed.
Other than premitive types how could you send data. I dont know if a complex type could be send as parameters to crystal report, but AFAIK it cant be.
I think the better way to create a list of all the available Reports that the crystal Report viewer might load and generate the parameters based on what is loading. If you know what data to be passed, you can easily generate the interface.

Dear All,
In download data module of my application(with asp.net2.0/sqlserver2005)one of the function is returning a datareader object having 7 hundererd thousands plus record. It returns the datareader without an exception but when i am iterating through the datareader to take its values to a string bulider type varible to write a csv file, it throws an 'System.OutOfMemoryException' due to huge records. I can not filter the record as it is required to write a csv file of the whole data. how can i avoide this error and improve the efficency of the system so that it takes less resources. The compilation debug is set to false. Also when there a few hundered thousand records the download is working ok. Thanks in advance for the help form any esteemed member.
Thanks,
Safvi

When you use a datareader, data is not fetched from the database until you use the Read() method to read the next row, therefore you may not receive an error when you open the datareader. The problem seems to be with StringBuilder. You can split the result into batches of say 10000 rows and then write them. For example, open the csv file write 10000 rows, close it, then append the next 10000 rows and so on. You could do this using a loop counter. Each batch would use a new StringBuilder instance to write to the csv file.

Hi everyone,
Please read the xml file below. Thanks.
(1). Given id="100" and quantity=2. id="100" exists in the xml file. Then update quantity (i.e., 1+2 = 3) in the xml file.
(2). Given id="300" and quantity=1. id="300" does not exist in the xml file,
then insert this new record (i.e., <item id="300"><itemName>Bike</itemName><price>150.99</price><quantity>1</quantity></item>)
into the xml file.
(3). Given id="200". id="200" exist, then delete this record (<item id="200"><itemName>Car</itemName><price>99.99</price><quantity>1</quantity></item>)
<products>
<item id="100">
<itemName>Car</itemName>
<price>99.99</price>
<quantity>1<quantity>
</item>
<item id="200">
<itemName>Car</itemName>>
<price>99.99</price>
<quantity>1</quantity>
</item>
</products>

The postback data won't be cleared and when you refresh, it will be resend. To work around this, consider redirecting the page after insert.
Response.Redirect("success.aspx")

but sir,i have a grid in that page and i want to show the values in the grid

This is the way ASP.NET postback works. When you refresh, your browser submits the same page with the same postback information. The only way you can avoid it is by redirecting it to a different page.
