Hello all, I'm writing my very first Telerik report. I am trying to hook up one of the parameters to a "Business Object" datasource.
My datasource is defined as:


My report parameter is defined as (from the report codebehind):


When i run the report in the browser, in the area where the report would normally render, it tells me: "The expression contains object 'Fields.Value' that is not defined in the current context." I have tried using Value, Fields.Value, Item.Value, ... and just can't figure out what to put for the DisplayMember and ValueMember to get them to pull the Text and Value properties of the ListItem objects respectively. I even tried leaving them blank, but then it tells me: "Parameter 'DeviceId' has defined AvailableValues, but no ValueMember is specified. Use 'Item' if binding to Array."

Can someone tell me what to put for the DisplayMember and ValueMember properties???
Thanks in advance! 

I have a report generated through the report wizard. I have set up three parameters, Service, Mod. Number and Status.

I have the filters working properly, but I would like for the user to have the selection to see Open, Closed or All in the status field.

The user can now select Open or Closed. If I set the MuliValue to true on the third parameter (status) and allow the user to "Select All", I get the following error on all selections:

An error has occured while processing Report: Cannot perform '=' operation on System.String and System.Collections.ArrayList.

Any help on this would be greatly appreciated.

Hi,
    I am generating cross-tab report for whole month. so based on status, i want to show colors. e.g. for 0-Green, 1-Red, 2-LightGreen, 3-Orange, 4-LightYellow, 5-LightPink. when i have given condition formating to first column, it wrote this many lines of code in to the designer. but i want to do it for 31 columns. what is the alternative for this? Also there is limitation of code is, my field will be changed at runtime. it is not fixed that, for txtD1, always field is Fields.D01.

please let me know. following is the code sample.

formattingRule1.Filters.AddRange(new Telerik.Reporting.Data.Filter[] {
            new Telerik.Reporting.Data.Filter("=Fields.D01", Telerik.Reporting.Data.FilterOperator.Equal, "3")});
            formattingRule1.Style.BackgroundColor = System.Drawing.Color.Orange;
            formattingRule1.Style.Color = System.Drawing.Color.Transparent;
            formattingRule2.Filters.AddRange(new Telerik.Reporting.Data.Filter[] {
            new Telerik.Reporting.Data.Filter("=Fields.D01", Telerik.Reporting.Data.FilterOperator.Equal, "1")});
            formattingRule2.Style.BackgroundColor = System.Drawing.Color.Red;
            formattingRule2.Style.Color = System.Drawing.Color.Transparent;
            formattingRule3.Filters.AddRange(new Telerik.Reporting.Data.Filter[] {
            new Telerik.Reporting.Data.Filter("=Fields.D01", Telerik.Reporting.Data.FilterOperator.Equal, "0")});
            formattingRule3.Style.BackgroundColor = System.Drawing.Color.Green;
            formattingRule3.Style.Color = System.Drawing.Color.Transparent;
            formattingRule4.Filters.AddRange(new Telerik.Reporting.Data.Filter[] {
            new Telerik.Reporting.Data.Filter("=Fields.D01", Telerik.Reporting.Data.FilterOperator.Equal, "2")});
            formattingRule4.Style.BackgroundColor = System.Drawing.Color.LightGreen;
            formattingRule4.Style.Color = System.Drawing.Color.Transparent;
            formattingRule5.Filters.AddRange(new Telerik.Reporting.Data.Filter[] {
            new Telerik.Reporting.Data.Filter("=Fields.D01", Telerik.Reporting.Data.FilterOperator.Equal, "5")});
            formattingRule5.Style.BackgroundColor = System.Drawing.Color.LightPink;
            formattingRule5.Style.Color = System.Drawing.Color.Transparent;
            formattingRule6.Filters.AddRange(new Telerik.Reporting.Data.Filter[] {
            new Telerik.Reporting.Data.Filter("=Fields.D01", Telerik.Reporting.Data.FilterOperator.Equal, "4")});
            formattingRule6.Style.BackgroundColor = System.Drawing.Color.LightYellow;
            formattingRule6.Style.Color = System.Drawing.Color.Transparent;
            this.txtD1.ConditionalFormatting.AddRange(new Telerik.Reporting.Drawing.FormattingRule[] {
            formattingRule1,
            formattingRule2,
            formattingRule3,
            formattingRule4,
            formattingRule5,
            formattingRule6});

I'm dynamically building a report from a set of parameters in an xml file.  I have categories defined in one drop down list and the list of reports in a second drop down list.  Changes to ListBox1 should only update the values in ListBox2 and changes to ListBox2 should only add textbox controls to Panel1.  However, when I change the values in either box the ReportViewer refreshes the current report.  Even if I change the value in ListBox2 I have to wait for the old report to refresh before I can hit the run button for the second report.

Any ideas?

Thanks,

Paul

I want to use reports in silverlight so I need  Telerik.Reporting.Service.dll 
and I didint fint it .

any help please ?

Hi

What is the best way to view Telerik reports inside a silverlight application, also i wish to pass parameters for the report from the silverlight gui ( dates etc. )

Regards,

Hello, this going to be a very specific scenario that I can't find any documentation on.

I created a Subreport that builds a chart that accepts a parameter  ( TerritoryId ),
when I run that report by itself it works fine. (see subreport.png )

When I create a Master report and pass in the parameter, the parameter seems to pass in ok. But the chart,
says Specified cast is not valid. (see master.png)
You can see from the msater.png that the parameter is being passed to the text box on the subreport, but not the chart.



The code for the  chart NeedDataSource on the subreport:

The attached images are the subreport by itself, and the subreport inside a master report, passing in the parameter.

This just uses the AdventuresWork DB
The following  is the StoredProc used for the dataset.


Here's how the designer code for the Master:

And the desinger code for the SubReport:

Basically the subreport has a textbox that echos out the passed in parameter and the chart.
running it alone the textbox populates and the chart populates.

Running the MasterReport with the Subreport , the textbox populates but the chart causes the cast error.

Dear Telerik,

Can you please help me, how do I do a group footer textbox which value based on group header textbox value.

For example. if the headerGroup textbox value is an "A" then the footerGroup textbox value should be the sum of "A".

Thank you for you Help
