Code Snippets

i am using VWG version 3 and this wrapper control is using version 2 i believe. when i tried to use it in my project (in VS 2008 VWG) it gave me an error about a conflect of versions i believe...

any ideas how to use this control? i am using VWG in Visual Studio 2008..

Thanks

I'm getting an error trying to incorporate this into my project. This demo runs fine - until you remove the CrystalReportViewer from the Form and try to readd it by dragging it from the Toolbox. Errors ensue. Please help! An email would be greatly appreciated.

Ok, I found the fix. The code that is generated when Dragging & Dropping the CrystalReportViewer onto a Form/User Control is incorrect. Here is the fix. Replace generated code with the code below. Enjoy!

[Put in Form/User Control ____.Designer.vb, anywhere a CrystalReportViewer is used]


Private Sub InitializeComponent()

Friend WithEvents CrystalReportViewer1 As VWGCrystal.CrystalReportViewer

Well, apparently - that code fixed the demo project contained here. I was able to remove the control from the Form and readd it, and overwrite the code generated within Designer.vb just fine. That seemed to fix the demo project.

However - when I attempted this in my own project - Visual Studio keeps overwriting my changes inside Designer.vb. I keep getting the "ToolbarStyle" "null is not allowed" error. Here is the code VS is generating, which seems to be causing the error:

--

'
'CrystalReportViewer1
'
Me.CrystalReportViewer1.Anchor = Gizmox.WebGUI.Forms.AnchorStyles.None
Me.CrystalReportViewer1.ClientTarget = "Auto"
Me.CrystalReportViewer1.Dock = Gizmox.WebGUI.Forms.DockStyle.Fill
Me.CrystalReportViewer1.DrilldownTarget = "True"
Me.CrystalReportViewer1.GroupTreeImagesFolderUrl = ""
Me.CrystalReportViewer1.HasRefreshButton = True
Me.CrystalReportViewer1.Location = New System.Drawing.Point(0, 0)
Me.CrystalReportViewer1.Name = "CrystalReportViewer1"
Me.CrystalReportViewer1.PageToTreeRatio = 0
Me.CrystalReportViewer1.PageZoomFactor = 0
Me.CrystalReportViewer1.PrintMode = CrystalDecisions.Web.PrintMode.Pdf
Me.CrystalReportViewer1.ShowAllPageIds = True
Me.CrystalReportViewer1.Size = New System.Drawing.Size(796, 789)
Me.CrystalReportViewer1.TabIndex = 0
Me.CrystalReportViewer1.Text = "CrystalReportViewer1"
Me.CrystalReportViewer1.ToolbarImagesFolderUrl = ""

How do I fix this? Please help! Email would be greatly appreciated.

Please i need a detailed example on how to use that. do i just add the DLL to my references and call the crystalreportviewer of the VWGCrystal?? or do i add a crystalReportViewer from the toolbox myself?? (when i do that, i dont see anything in the form, as if it did not add anything!!). also do i need to add anything to the web.config?? does it matter if i am using version 3 of VWG?

Please help

Thanks

To use this, you add the CrystalWrapper file to your project, then rebuild. Now go into Design view of your Form or User Control - you will see the CrystalReportViewer in your Toolbox under the name of your project. Drag this onto the Form or User Control.

Problem is - the auto-generated code in the Designer.vb files causes errors.

All I get is errors, continously. "ToolbarStyle null"

Please help!

Hi,

I figured out what seems to be the wrapper's problem. In order to stop these annoying messages from the designer, you'll have to add default values to some of its properties:

1. Return GetObjectParam("ToolbarStyle", New ToolbarStyle())
2. Return GetObjectParam("GroupTreeStyle", New GroupTreeStyle())
3. Return GetObjectParam("PrintMode", PrintMode.Pdf)

Hope it helps,

Hi,

I uploaded a new version of the ZIP file as well - for your convenient.

Shlomi

perfect...i got it to work on my machine finally :) but now i have a small problem!! when i run the application on the deploying machine (which doesn't have crystal installed) i get this error:

"Could not load file or assembly 'CrystalDecisions.Web, Version=10.5.3700.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' or one of its dependencies. The system cannot find the file specified."

does anyone have the msi file to add these dlls to the deploying machine? the deploying machine only have these dlls in version 10.2.3600.0

Please help...i need this ASAP

Thanks alot for all the hard work!

First of all I would like to excuse me for my English.

I have add as reference, the VWGCrystal.dll. I drag and drop the CrystalReportViewer(the control that was generated from the dll) on the form and when the project is being compiled an exception is shown at the mozila

I'm getting the same error today like oti @ Tuesday, May 27, 2008 4:21 AM above is.

I'm using IE7 and Crystal 11.5.3700.0

Help!!!

Also, the .Zip file does not contain the two tester projects that are referenced in the Solution File - ASPCrystalTester and VWGCrystalTester.

How can I acquire?

Ok, I have everything working great on Crystal 10.x

I've created a demo project for you all. Hopefully it works on 11.x as well.

PS. I wish I could upload code to this VWG website instead of my own. Permission denied when I tried adding a Code Snippet.

Also, To install Crystal Reports on the deployment server using MSI Redistributable - you can find the MSI file in your local Visual Studio folder:

C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\BootStrapper\Packages\CrystalReports\CRRedist2005_x86.msi

Ryan, thanks for the code, it helped.

Hi Dennis,

What build of VWG are you using?

I'm using v6.0.2 and that code works fine for me.

Ryan

Ryan,

I'm using .Net 2.0 build 5.84.2

Will do upgrade and advise.

Thanks...

Ryan,

I upgraded to v6.0.2 and form rendered!

I did however, had to add the following to
VWGCrystalViewer.Designer.vb:

Dim myToolbarStyle As CrystalDecisions.Shared.ToolbarStyle = New CrystalDecisions.Shared.ToolbarStyle
Me.CrystalReportViewer.ToolbarStyle = myToolbarStyle

The only other thing to do is find the images to
add to the ToolbarImagesFolderUrl property.

Thanks again for the help.

Glad you got it to work!!

To get the Crystal Toolbar Images - simply copy the aspnet_client folder from my project into the root folder of your VWG project.

Should be good to go.

Ryan

When I add images to a crystal report, the embedded images are not shown when the application is running.

Is there a specific folder that this images should
be in.
Currently for the images I'm using the default resources/images folder

This cystal wrapper, is avaible on VWG version 3 and VS 2008 VWG??

when i try to open the 'VWGCrystal.vbproj' file i face this problem:


Microsoft Development Environment
---------------------------
Unable to read the project file 'VWGCrystal.vbproj'. The file 'D:\E_Books\VB.net\CrystalReportCode\Gizmox.WebGUI.CrystalReports.CrystalReportViewer.1.2\VWGCrystal.vbproj' is not a valid project file. The project file is missing the 'VisualStudioProject' section.

Hi,

I'm having problem in printing the report. The pint button points to a dialog which always exports the report in PDF. When I changed my default printer from Adobe PDF to some other it doesn't work. It shows page cannot be displayed error.

Gizmox - can you please post the newer Crystal Reports wrapper here? This is an old version of the Crystal Wrapper. I have a demo here:

http://support.visualwebgui.com/issue/ViewIssue.aspx?ID=3764

However - I do not see how Design-time is NOT supported now - but it was supported previously in older versions of this wrapper.

Ryan

i'm using this control
so far is good enough

but when i'm working with chart report and i deploy it on server why my chart doesn't appear on report?
is there some of u guys know why

Thanks
warm regards,

Rochmad

Hi Rochmad -

This code is now deprecated. Please see new Crystal Reports Viewer here:

Ryan

Hi Ryan,
Thanks very much,
i'll try it
