Question : SQL Reporting Services - UK Date Format and Parameters

I have a report that I've developed that accepts several datetime parameters.
 In the Report properties, I've set the report Language to English (United
Kingdom).

I am calling my report via the Web Service from an ASP.Net application.  The
ASP.Net application Culture and UICulture are set for en-GB.

What is happening is that when a date is passed to one of the report
parameters (gEndDate) as "14/12/2004" (December 14), I get the following
error:

The value provided for the report parameter 'gEndDate' is not valid for its
type

If it helps any, my Visual Studio .Net environment where I am developing the report and Asp.Net application are on my laptop in the en_US language setting.  The test machine where I am having the error is en-GB.

Answer : SQL Reporting Services - UK Date Format and Parameters

Simple option first... can you not just set your laptop settings to en_GB ?

I've had similar problems with date formats in the past and ended up converting the date within my dataset to a different format so that the parameter would pass correctly.  Try something like : DATENAME(day, YourDateField) + ' ' + DATENAME(month, YourDateField) + ' ' + DATENAME(year, YourDateField) on the datafield that is used in your report, and then set your parameter to show the same format.
