Hi,my problem is that I have to use more than one stored procedures for different parts of my report.
For example if I have three parts in the report I have to use three stored procedures which provide the data.

Hi there,
I am using the web report viewer. My report has one parameter called 'ClassName' which is added to the report by code. The data source of this parameter is from a query. if the data source is an empty collection, the report viewer shows '<select a value>' in the parameter combo box which is fine. If I click the Preview button it shows 'Please input data for all parameters' which is also fine. However, whenever I click the refresh button or click the Export button(after selecting a format) on the viewer tool bar, I will get the following error:
Exception Details: System.Exception: Invalid value of parameter 'ClassName'.
Source Error:
Stack Trace:
Is there a way to handle this error? It should show 'Please input data for all parameters'.
Please help.
Thanks,
Richard

I have a group summary item that has the following expression:
= (Sum(Fields.ActualAttendance) / Fields.DaysTaught)
Actual attendance and DaysTaught are integers. i would like to display the result with single precision decimal. How can I do this in an expression? The problem is that the integer arithmetic is returning a tuncated integer so using the format option always display .0
What I need is to cast the integers to decimals beforehand.
Thanks

Hello,
When I create a new report using the Telerik Reporting Template in Visual Studio 2010, there are a number of changes I need to make each time. Can the VS Template be modified to avoid this repetition or is there another recommended technique?
Thanks!

Hi,
I am slightly confused with multi select parameters - can these be automatically passed through to a SqlDataSource (referencing a stored procedure) as a comma delimited list, or do I have to manually create this string in the NeedDataSource event?
Thanks

Hello,
I have an untyped data source (and no I can change it) where all my columns are strings. I have a "date" column which I would like to format specifically so I am trying to convert the field value to a date using the following:
=IIf(Fields.MinDate='', 'blank string', CDate(Fields.MinDate))
The problem is that the one record I have with a blank string as a value is erroring out on the CDate conversion, which it shouldn't because it evaluates to "true".
If I use:
=IIf(Fields.MinDate='', 'blank string', Fields.MinDate)
then the record does display 'blank string' so I know that it is evaluating to "true" for that record.
Any ideas on how I can convert this string field to a date so I can apply special formatting (without having to write a user function)?
Thank you.

Hello,
I have following problems with telerik reporting (web report), so every help is appreciated.
1. Visibility with conditions is not working properly - when textbox, panel or datatable is by default set to visible=false,
then conditions won't trigger to show it (condition is ok, because it works other way -> default=visible, script hides it)
2. When two panels are same width and height, and are overlapping completely, one is hidden, one isn't (with script) then it causes rendering problems (none of them is visible)
3. Impossible to hide datatable column with conditions, even if i can set condition on table title and column record definition cell.
4. Impossible to control position of the item using conditions. (this is a wish to feature) Ideally telerik should be able to control with conditions every parameter of an object, or atleast those that are related to showin/rendering.
5. Instead of this semi-script language, full c# lang. syntax could be supported including direct calling public methods from any c# object
