AJAX & ReportViewer

Question

Hi,

My problem is:
I want use AJAX components (AJAXControlToolkit) and it works fine. But when I put ReportViewer on my page strange things happens. ReportViewer or AjaxControls don't work properly, or even don't work at all.
I don't know what to do... Help me plz...

Answer 1

Hi,

As far as I know, ReportViewer needs a full postback to work so it won`t work inside an Ajax UpdatePanel if you don't set a full postback trigger.

A few weeks ago, I tried to insert a reportViewer inside an updatePanel, but It did not work at all, ( I had a child-parent report). After searching in this forum and over the internet, I got the answer that It doesn´t work.  Maybe one of the MSFT could clarify a bit more the issue

Hope this help

Answer 2

Last time I tried it ,about 4 months, i could get it to work as long as your report didn't require the user to interact with it at all. If I'm not mistaken I had to set AsyncRendering or something along those lines to false.  A far better solution, especially if you don't know your users resolution settings or if your rendering large reports is to use the following lines of code and place your reportviewer in a new window.

string query = "window.open('Report.aspx?passmyparamshere','new_Win');";

ScriptManager.RegisterStartupScript(Page,Page.GetType(),"wOpen", query, true);

 

Answer 3

Due to the way the report viewer uses script, it is currently not compatible with an UpdatePanel.  We are aware of this problem and looking into the necessary changes to get the ReportViewer working in an UpdatePanel.  But at present, there is no work around.  While it may appear you can get simple reports working in this scenario, some of the more subtle report viewer behavior will still be broken, such as its code that keeps the report session alive when the browser window is left open.

Answer 4

I was planning to implement ajax control with report viewer, but not any more. My main problem is cascading parameter doesn't work with rs webpart in sharepoint 2007. same problem with regular reporting services subscription and cascading parameter.

Answer 5

Does "not compatible" include scenarios where a reportViewer shares a page with an update panel, but does not reside in it?  I have the following scenario:

<update panel>

   <usercontrols for parameter input />

</ update panel>

<asp button triggering full postback and loading report />

<report viewer />

 

On the second and any subsequent postbacks a javascript alert box pops up with a Specified Argument out of range... message.  Clicking the button after triggering this message results in the full error below.  I've tested the full setup without the update panel and the update panel without the report viewer, and both parts work correctly. Only when the two co-exist on the page does the error occur.

 

If I should be able to make this set-up work and am just missing some piece, please let me know -

Answer 6

Lambrite, did you ever find a solution for this?

 

I have a page layout simliar to yours.  The problem in my application is slightly different than yours.  In my project, I have two dropdown lists, a button and a ReportViewer control.  As follows:

 

<asp dropdownlist/>

 

<asp updatepanel>

<asp dropdownlist/>

</asp updatepanel>

 

<asp button triggering full postback and loading report />

<report viewer />

 

Whatever is selected in the first dropdown list determines what gets displayed in the second dropdown list.  If I select something from the first dropdown list, select another value from the second list, then hit submit, I get the "full error" you described.  BUT, if I just select from the second dropdown list, and then hit submit, it works fine.  And then, if I select from both dropdown lists -- first dropdown list, and then the second --  and then click submit, it works fine.  As it should when I come to the page for the first time, but it doesn't.

 

This is a big bug, IMHO.

Answer 7

 

I found a solution for this.

 

In the aspx page, set the ReportViewer visibility to false.

 

<rsweb ReportViewer Visible="false"/>

 

In the button_click event, set the ReportViewer visibility to true.

 

ReportViewer1.Visible = True

 

Seems to work fine for me, so far.

Answer 8

This does work, although in my case it means that the user cannot see the parameters for the report at the same time as he sees the report, which is acceptable though undesireable.  Hopefully, they'll get a real solution worked out soon.

Answer 9

You can write a user control that calls the Report Web Service and generates an interface for the report. I thought this would be a huge project but it wasn't and I even use AJAX control toolkit items.

 

Answer 10

Can you elaborate?

 

I'm running into a plethora of problems trying to simply refresh a report with parameters.

using Microsoft.Reporting.WebForms;

using System.Collections.Generic;

namespace MaskanProject.Common.Controls

private string EmumProperties()

{

string paramsString = String.Empty;

ReportParameterInfoCollection collect = null;

if (ProcessingMode == ProcessingMode.Local)

{

//???

}

else

{

collect = ServerReport.GetParameters();

}

if (collect != null)

{

foreach (ReportParameterInfo param in collect)

{

paramsString += "&"

+ param.Name

+ "=" + param.Values.ToString();

}

}

return paramsString;

}

public string BuildUrlString()

{

string url = string.Empty;

if (ProcessingMode == ProcessingMode.Local)

/// Render the report in an IFrame

/// </summary>

/// <param name="output"></param>

protected override void Render(HtmlTextWriter output)

{

// Create IFrame if the user enters ServerUrl and ReportPath

output.WriteBeginTag("iframe");

output.WriteAttribute("src", this.BuildUrlString());

output.WriteAttribute("width", this.Width.ToString());

output.WriteAttribute("height", this.Height.ToString());

output.WriteAttribute("style", "border: 1 solid #C0C0C0");

output.WriteAttribute("border", "0");

Hi there. Note that the ReportViewer control in the upcoming VS2010 release will be an AJAX control, fully compatible with UpdatePanels.

Did anyone have any luck in trying to get the reportviewer in VS2010 work in an updatepanel?

I tried but could not get it to work.

Answer 21

Can you elaborate on "could not get it to work"?

Answer 22

In VS2008 like others have mentioned in the thread above ReportViewer was not compatible in an updatepanel.
In many of the forums I have seen assurances that in VS2010 this would be address.
So my question was has anyone tried to make it ReportViewer work in an updatepanel in VS2010? I tried but could not get it to work.

 

Answer 23

Still not sure what "could not get it to work" means. Errors? UI behavior?

I just tested the following steps and they do work. Let me know if these are the same steps for you.

1) Drag a ScriptManager to the form

2) Drag an UpdatePanel to the form

3) Drag a ReportViewer to the form inside the UpdatePanel

4) Configure the ReportViewer for the appropriate report

5) Run the app

Answer 24

Hi Craig,

I have the the same problem with ReportViewer control and RadAjaxManager. The solution what you said is helped me in solving my problem.

Thanks!

Answer 25

I got it to work too Cephalin thanks. I think I know why my initial attempt failed.
The project that I was working with was built in VS2008 and I upgraded it to VS2010. I am still having issues with that one.
But when I create a new project it VS2010 I have no issues.

 

Answer 26

For your upgraded VS2008 project, you'll need to update your references from the 9.0 viewer to the 10.0 viewer. This needs to be done in the project's References in solution explorer, in the Web.config, and at the top of your ASPX file.

Answer 27

Craig, et al - 

I was able to get the RadAjaxManager to help with a bunch of controls (stop page postback after each control update) and then click a button and show and run the report using the visibility = false and true switch.

However, when the user goes back and tries to change a value in one of the controls, the code behind is not working and I am getting the 'specified argument out of range' error again.

Does anybody know of a way around this?

I tried to use some events to make the reportviewer.visibility false again, but it isn't working.

So frustrating.

How can we use ajaxified controls and the reportviewer on the same page?!

Thanks for any help.

-M

 

Answer 28

Hi All,

Even I am struck with the same issue with ajaxified control and a reportviewer on a page. (report viewer 10 )

when some dropdown value is changed in the control, the reportviewer used to load back with the updated parameter, thou I stopped that by using some variables..

but the still ther reportviewer gets disabled and enabled when the page post back happens and the scroll bar is set top of the page

Please let me know if any of you have any solution for this issue..

Thanks in Advance
