Recently we had the requirement in our project where the customer wanted to execute the Export To Excel feature for an editable grid that we implemented. The following in an overview of the requirement.
1. There is a custom jQuery Grid which shows a consolidated view to customer for a custom entity and its related child entities. The grid is an editable grid which was accomplished through a CRM webresource.
2. For that grid, the customer wanted an export to excel feature with the following functionality
- Excel report in the same format as the grid is appearing
- Excel report would give the user option to
1. Export selected rows
2. Export all records on the current page
3. Export All records.
To meet the above requirement we did the following.
1. Created a webresource in CRM with the same look and feel as OOB Export To Excel pop-up, with the options the user was looking for.
2. Created custom SSRS reports in the same format as the grid and deploy it to the report server
3. Set up a custom website (CRM 2013) or Web application under ISV folder (CRM 2011), call the website page with the user choices passed as the querystring and execute the SSRS report based using asp.net code in the page
The following is the code to render the ssrs report to the client in excel format. Add a reference to Microsoft.ReportViewer.WebForms dll in your code and include the namespace Microsoft.Reporting.WebForms.
// Parse the query strings. The querystrings would be basically your user choices
<Your logic goes here>
var reportViewer = new ReportViewer();
reportViewer.ProcessingMode = ProcessingMode.Remote;
// Set the username and password for connecting to reportserver
var domain = ConfigurationManager.AppSettings[“ServerDomain”].ToString();
var userName = ConfigurationManager.AppSettings[“ServerUsername”].ToString();
var password = ConfigurationManager.AppSettings[“ServerPassword”].ToString();
IReportServerCredentials irsc = new CustomReportCredentials(userName, password, domain);
reportViewer.ServerReport.ReportServerCredentials = irsc;
// set the reportserverurl. Typically it would be in the format of http://<servername>/ReportServer
reportViewer.ServerReport.ReportServerUrl = new Uri(ConfigurationManager.AppSettings[“ReportServerUrl”]);
// set the report path i.e the path where the report has been deployed in the report server. You do not need to specify .rdl extension here.
reportViewer.ServerReport.ReportPath = “/TestReportFolder/TestReport”;
//populate the parameter list if any paramter is required by the report from the querystring.
var paramList = new System.Collections.Generic.List<Microsoft.Reporting.WebForms.ReportParameter>();
//for example, here i am passing the loggedin userid and the report is expecting a parameter @UserId
paramList.Add(new ReportParameter(“UserId”, userid));
reportViewer.ServerReport.SetParameters(paramList);
// declare variables
string mimeType, encoding, extension, deviceInfo;
string[] streamids;
Microsoft.Reporting.WebForms.Warning[] warnings;
string format = “Excel”;
deviceInfo =
“<DeviceInfo>” +
“<SimplePageHeaders>True</SimplePageHeaders>” +
“</DeviceInfo>”;
byte[] bytes = reportViewer.ServerReport.Render(format, deviceInfo, out mimeType, out encoding, out extension, out streamids, out warnings);
// set the excel file name
var fileName = “ExcelFile.xls”;
Response.ContentType = “application/excel”;
Response.AddHeader(“Content-disposition”, “attachment;filename=” + fileName);
Response.OutputStream.Write(bytes, 0, bytes.Length);
Response.End();
and following is the code for the class CustomReportCredentials
internal class CustomReportCredentials : IReportServerCredentials
{
private string _UserName;
private string _PassWord;
private string _DomainName;
public CustomReportCredentials(string UserName, string PassWord, string DomainName)
{
_UserName = UserName;
_PassWord = PassWord;
_DomainName = DomainName;
}
public System.Security.Principal.WindowsIdentity ImpersonationUser
{
get { return null; }
}
public ICredentials NetworkCredentials
{
get { return new NetworkCredential(_UserName, _PassWord, _DomainName); }
}
public bool GetFormsCredentials(out Cookie authCookie, out string user,
out string password, out string authority)
{
authCookie = null;
user = password = authority = null;
return false;
}
}
And the user would get a pop-up from the browser to download the excel file.
Hope this helps!
