AJAX :: Report Viewer Problem !!! Ajax Like Update Progress In Javascript?

Jun 12, 2010

I'm using a an Ifram that switches between several pages, each page contain a report viewer and takes time to load (about five seconds) since I'm using an Ifram the end user will not notice the loading of the page behind the seen (report pages) he will only notice a quick loading of the Ifram page ! so I tried to use the update panel and the update progress to show a waiting or loading progress image when the page loads or post back . but this doesn't work in Ajax since Ajax is not compatable with the report viewer .is there any way to show a progress waiting message during the page load using Javascript ?I Found many scripts like this that show a waiting message or image BUT the script starts after the page loads completely (a silly loop for 3 seconds maybe then hide the message )

AJAX :: File Upload Control Not Working In Update Panel?

Feb 15, 2011

I have 3 upload controls ,one listbox and two button controls in page. One button control named Attach has the code to add the files to listbox form 3rd file upload control and the 2nd button control named Save has the code to save the files of 1st and 2nd file upload controls in application folder and items of listbox to database.

The issue is couldn't maintain the state of 1st and 2nd file upload controls after browsing the files to file upload controls and clicking on Attach button control to add file name to listbox which was browsed by 3rd file upload control.So i placed the 3rd file upload control, Attach button and listbox in update panel but its not working. My requirement is when clicked on save button files of 1st and 2nd file upload controls in application folder and items of listbox to database, but 1st and 2nd file upload controls will loose the files as soon as Attach button is clicked to add filename of 3rd fileupload control to listbox.

AJAX :: Update Panel - Asp Panel Not Working Properly

Jun 8, 2010

I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.

I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.

When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.

I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.

I have an ASP.Net (.Net 2.0) application that creates Crystal Reports (version 11.5) and shows them with CrystalReportViewer control. For some reason the control isn't showing the logo image in the header of the report. It renders the following html

<img width="320" height="76" alt="Imagem" src="CrystalImageHandler.aspx?dynamicimage=cr_tmp_image_e47fba99-96fc-471b-ab11-06fd2212bbdd.png" border="0"/>

I already included the aspnet_client folder in my Virtual Directory in IIS.

Report Viewer From SQL Reporting Services In VS 2008 Report Control?

Jan 8, 2010

Report viewer from SQL reporting services in VS 2008 report control If I create a new report in VS 2008 they have a .rdlc extension and work correctly.

I have some reports that I was using in SQL reporting services. Extensions are .rdl and want to get them to work with VS 2008.

I copied the rdl files and the .rdl.data files over to VS 2008 (SP1) project but when I go to select the report in the control it does not see the file (I assume it is looking for a .rdlc file)

I tried rename the file to .rdlc and loaded the file up and got

The report definition has an invalid target namespace [URL] which cannot be upgraded.

I see this



It says

"RDL files are fully compatible with the ReportViewer control runtime. However, RDL files do not contain some information that the design-time of the ReportViewer control depends on for automatically generating data-binding code. By manually binding data, RDL files can be used in the ReportViewer control."

But the link for how to manual bind the data is broken.

SQL Reporting :: Report Viewer Not Working?

Apr 10, 2010

I had some problems with Visual Web Developer Express 2008 recently, so I decided to reinstall it.Since then I have not been able to get ReportViewer to work again.When I try top open an rdlc file in the VWD environment, it opens in source view not design view. So I can not edit it, the way I normally would.I cannot add a new report. However the reports I have already created still work when I run the application.have tried unistalling and reinstalling everything, SQL Server Express 2008 (SP1), Visual Web Developer 2008 and Microsoft Reprt Viewer Redistributable 2008.I can not seem to get the environment back to how it was before.

Crystal Report Viewer Tool Bar Options Not Working?

Jul 25, 2010

I have an ASP.NET webapplication with an Oracle11g backend using DevArt's Oracle data provider.

The application works fine however when producing Crystal Reports, the web Crystal Report viewer renders only the FIRST page and none of the toolbar buttons function (ie: next page, zoom, export, search ...) The Group-tree and Prameters views will toggle, but nothing else seems to work on the web Crystal Reports Viewer (neither on my local nor on the server). The group tree shows all of the appropriate groupings collapsed - however when clicked to expand, I get an animated gif at the expand icon (+) but nothing else happens...

Update Panel Not Working In User Control

Nov 12, 2010

I am fixing issues in a project where I was not able to figure out a solution for the below problem. There are multiple user controls in Main.aspx page. First one is header.ascx which is added directly in .aspx page. and the others are added dynamically from Page_Init event. Basing on the hyperlink clicked from the menu on the left side of the main page, the respective user control is displayed.

Now, If I try to add script-manager/update panel inside any of the dynamic user controls, the respective user control page throws error. I have noticed that the header.ascx control is using scriptmanager. Is it creating the problem? How to handle this kind of issue?
