I read the "Understanding Events" article and have been researching different posts on this subject and I'm still a little confused.  I want to use the runtime value of txtElement in a query to return an amount.  I then want to set the value of txtEncumbrance to the amount that is returned.

All of my fields are in the group footer section.  But I know I need to get the value of my text box in the ItemDataBound event of my text box first using the sender object.  Should all my code go there?  Or should I put the rest of my code in the group footer ItemDataBound section? 

Please see attached files.  Thanks for your help!

Hello,

    I'm new to Telerik Reporting, heck I'm still using a trial... but I'm getting this error while trying to put a Report Viewer onto an aspx page within an already built web application as a trial run.....
    

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)

It is an ASP.NET 2.0 web page that has a master page.... 

I did build the report in a separate class library, and it works fine (connecting to a MySQL database and retrieving a simple set of data).

this is the code for the aspx page..... I've added no code to the aspx.cs ..... as it is not needed to view a report (I've done a trial run on a new web site earlier as another test, but now i'm trying to incorporate a report into a system)

===========================================================================================================

<%@ Page Language="C#" MasterPageFile="~/ApplicationLayout.master" AutoEventWireup="true" CodeFile="TestReporting.aspx.cs" Inherits="TelerikTest_TestReporting" Title="Telerik Test" %>

<%@ Register Assembly="Telerik.ReportViewer.WebForms, Version=4.0.10.423, Culture=neutral, PublicKeyToken=a9d7983dfcc261be"
    Namespace="Telerik.ReportViewer.WebForms" TagPrefix="telerik" %>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
    <div>
        <telerik:ReportViewer ID="ReportViewer1" runat="server">
        </telerik:ReportViewer>
    </div>
</asp:Content>

======================================================================================================

At the moment.... I'm not connecting it to any report, as I just need to know if the viewer will display.... but it does not, I just get that error.

Oh, and I have searched this forum earlier for anything related to this error..... If I take the runat="server" away from the report viewer, the viewer does not show up on the page at all, but I don't see that error message come up.....

what do I do to get the viewer to display..... after I have it working can I attach a report to it.....   please help

hi,

i have a very simple report and i have a window with ReportViewer.
in design time at the XAML source - defining the report viewer ZoomMode to Pagewidth i noticed that later on runtime the vertical scroll doesn't work, it's just stuck, sometime the scroll locks, looks like disabled, only when i change the zoom from the report viewer the scroll functionality returns.
it only happen when in full screen and only in PageWidth ZoomMode.

can you plz help?

thanks,
lior.

hello,
i create a telerik report using telerik report table follow the wizard, but when i export data to excel or any format a error occur like the attached files

I cannot get the Designer to work anytime I have report logic that references an external DLL.  This includes using the Enterprise Library DLLs for data access and also using user-defined functions that reference external dlls for formatting.

Here's a sample _NeedDataSource event.  It works fine at run time in the viewer, but the designer does not work at all.  (just like with external format functions I reference). 

 

 

 

Any suggestions?

Hi,

Is there a way to retain the printer settings?

I generate and print a report.  I change the printer settings in the printer properties dialog box for example select a colour print.
When I generate another report I must then make changes to the printer properties again.

Is there a way to keep the changes I made the first time?

Cheers,
Gary

But I get the error below on ReportParameter:


Is there something I need to add?
