I'm using Asp.Net AJAX UI controls to display a RadGrid on a page with a ReportViewer underneath.  When the user selects a row in the RadGrid I want to capture the ID field from the selcted row and update the ReportViewer by passing that same ID to the newly instantiated report.

Has anyone done anything like this?

I can capture the needed ID from the client-side of the RadGrid, but I can only update the ReportViewer on the server-side.  I guess if I knew how to capture the RadGrid selected row on the server-side I could manage just fine.

i set up a new development machine and now i am getting the following error when i try to open the design view of a report:

Value cannot be null. Parameter name: instance

the sources, assemblies and web.config is all the same as on the other machine where it works.
i tried to rebuild the project, restart VS2008 but nothing helps.

any hint would be highly appreciated
regards

Hi,

I'm getting an exception when I close the form containing a report viewer,
while it's generating the report.
On slow machines, the generating of the report can take some time,
and users might close the form before the generation is completed.

How should that exception be handled ?

Thanks,

Hello,
         I had used report viewer in Telerik:Popup control,
         I have bound data to report viewer through data source with wizard.
         But, it takes too muck time to load the data in the report viewer.     

         Please reply me as soon as possible.

         Is there any problem with the use of report viewer in Pop Up
         or it can be problem with the use of data source, as i bring data from many tables with the use of inner join.
  
Thanks,

Hi team:
      I have set the report to page break,and show well in aspx web page,but after export to excel all the data show in one sheet,I think the data should come on a different sheet. Example Sheet1, Sheet 2,etc Any ideas.

thanks

Hi...
May i assign more than one reports to  the same report viewer ?
If yes then how ?

For some reason I am struggling to use / in certain circumstances. For instance I have two calculations:

=SUM(IIf(Fields.[DAYS_DELINQUENT]>29, Fields.[PRINCIPAL_BALANCE],0)) / SUM(Fields.[PRINCIPAL_BALANCE])

=SUM(IIf(Fields.[DAYS_DELINQUENT]>29,1,0)) / Count(Fields.[LOAN_NUM])

The first expression works without a problem. The second expression always comes back with an answer of 0.

What I have found for the problem expression is:

1. If I take out the 1 and replace it with a field (but not a report parameter) it then calculates
2. If I take out the / and put in a + then it calculates properly
3. What I put in the divisor is irrelevant based on about a dozen different tested changes (other functions, fields, static number, etc.)

Has anyone experienced this issue or know what I could be doing wrong?

Thanks for any help you can provide

Hi there
   I am newbie to this Telerik Reporting and trying to get use to simple reporting stuff with crosstabs. I have a simple datatable that need to be shown as exactly in report and counting the totals.
Design:

•  Having a cross tab control with text fields as exactly populated in DataTable, in the Detail Section.
• Having a Chart control in the Detail Section
• DataFields are assigned in the Value Property of textboxes like "=Fields.<ColumnName>"

Code:

• At the constructor level, i loaded the Report Page datasource with the DataTable i have.
• Chart NeedDataSource event also loads the chart's datasource with the datatable.

Problem:

•  Though the Chart loads the data perfectly, the cross tab throws instantiation error (Object reference not set) on each of the textbox those value property are set to "=Fields.<ColumnName>".
• And also i see chart and this cross tab with one data row (with error text on each bounded column) per report page and is repeated in seperate Report Pages for the number of rows i have in the DataTable.

Questions:

• Please explain me the behaviour of why the report page is repeated the times of records.Is that because i load the datasource to the page  like this.Datasource = dataTableObj;  in the Report Page constructor. But i referred the examples you guys gave in CSharp.ReportLibrary Dashboard example for loading the crosstabs in Detail Section and i just followed that. Please correct me where i am wrong
• Also suggest me the best way to show simple tabular data in reports that can extend more than a page.

I greatly appreciate any guidance from this active community sooner.

Thanks in advance
