Default File name with timestamp


hi fiends,

Can any one help me on this issue please. I am new to this SQL Reporting service.

Using SQL Sever 2005 , windows 2000 professional
Not able to rename the file , when i export the data into excel/pdf format. I tried with Subscription properties. It's giving the RDL name only.
My requirement is need to display filename appending with timestamp.

Steps:
1. I created RDL
2. Opening the RDL data into my GWT application with new IE window
3. Exporting the data into excel/pdf.
4. Able to popup Download file Dialog.
5. Asking the File to save. ( Here by defualt it's giving the RDL File name only. I want to display with RDL file name with timestamp)

Can you please help me.

 Hello Bhushanam,

 Even i have got the same problem. I solved the problem by overriding render method with the following code.

put below code in button click event

private void lnkexport_Click(object sender, System.EventArgs e)

{

ReportingService rs = new ReportingService();

string reportPath=/SampleDetail/TestingDetail;

// TestingDetail report must uploded in SampleDetail folder in ReportManager


TestingDetailReport testingDetailParams =this.reportParams as TestingDetailReport;

ParameterValue[] parameters = new ParameterValue[1];


parameters[0] = new ParameterValue();

parameters[0].Name="parameterName";

parameters[0].Value=parameterValue;

Byte[] result = this.LoadReport(reportPath,parameters);


string fname = "TestingDetail" + " - " +DateTime.Today.ToString("MMMM-dd-yyyy");


Response.ClearContent();


Response.AddHeader("Content-Disposition","attachment; filename=" + fname);

Response.AddHeader("Content-Length", result.LongLength.ToString());

Response.ContentType="Application/pdf";

Response.BinaryWrite(result);

Response.Flush();

Response.Close();

}



private Byte[] LoadReport(string reportPath,ParameterValue[] parameter )

{

ReportingService rs = new ReportingService();

rs.Credentials = System.Net.CredentialCache.DefaultCredentials;

string[] streamIDs;

string optionalString = null;

ParameterValue[]optionalparams =null;

Warning[] warning = null;


Byte[] output= rs.Render(reportPath,"PDF",null,null,parameter,nul l,null,out optionalString,out optionalString,out optionalparams,out warning,out streamIDs);

return output;

}
