Separate Date and Time report parameters in SSRS 2005



Is it possible to declare separate report parameters in SSRS 2005 as Date and Time?

I want the user to be able to enter a date and a time.

When I declare the parameters in my stored procedure as datetime, in SSRS the parameter just shows as a Date only.


Typed DataSets in .NET

we can specify the data type when we create a DataColumn for a DataTable. This is to enforce the runtime type-safety for the column so that only data of specified data type can be stored in the column

UnTyped DataSets and Strongly Type DataSets

We all are use datasets as a means of carrier of data from one layer to another. Most of the time we are using weakly typed datasets. In this article I will explain the differences between weakly typed datasets and strongly type datasets

Alternating row background for first column of a report


is there a way to make the first column of a report use the an alternating background color? 

I have the background color set for the entire row however it does not work for the first column if the color is set to an expression.  If I just set it to a color i.e. red it works just fine. If I insert a dummy column to the left it works just fine (but the dummy column does not work, presumably because it is first??).

In the file below only the textbox for part number does not show an alternating background.  All others work correctly.

                    <Textbox Name="PartNumber">

Need Syntax To Make Results of LINQ Union Return Non-Generic Type



I have the below SQL which works just fine:

SELECT     Message, CreateDate, AccountId, AlertTypeId
FROM       dbo.Alerts
SELECT     TOP (100) PERCENT Status, CreateDate, AccountId,
                          (SELECT     10 AS Expr1) AS AlertTypeId
FROM         dbo.StatusUpdates
WHERE AccountId = PassedInParameter

I have been going about trying to convert the above into a LINQ method and am having problems with return types.
As the above SQL illustrates, I am querying two distinct LINQ tables - Alerts and StatusUpdates -
and then attempting to perform a Union on them. In order to do the union in LINQ, I have to have agreeing types. So, I
am using "var" to make the results of "alerts" and "updates" generic before the union.  

public IList GetStatusUpdatesAsAlertsByAccountId<T>(Int32 accountId)
            using (WorkbookDataContext dc = _conn.GetCont

Hi all

I have a button "Show Report" to show some data from table

A connection could not be made to the report server http://localhost/ReportServer.



  • I created a Report using Business Intelligence Studio. Its working working well, i can able to view records. But when i try to deploy the report an error occurs specifying that "A connection could not be made to the report server http://localhost/ReportServer. (Microsoft Report Designer)".
  • I open the IIS 7 and find out virtual directories "Reports" and "ReportServer" are available.
  • I check on the browser and type "http://localhost/reports".  I find the browser direct to this url: http://localhost/reports/Pages/Folder.aspx and find error specifying the following one:

         Error:The report server is not responding. Verify that the report server is running and can be accessed from this computer.

  • when i type http://localhost/reportmanager, i found the error:

    HTTP Error 404.0 - Not Found

    The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

Printing crystal report from webservice



I am trying to print crystal repot directly from a C# application, which is calling webservice. I am able to display report in crystalreportviewer by passing the webservice call to datasource. However, is there anyway, I can print directly without showing the report?

Alternatively, I was trying return ReportDocument object from webservice, which would solve my problem, but I was unable to return the ReportDocument because of serialization issue. Is it even possible? Thank you
