question about CRI in reporting service

[saraMoghazy]

i have question please and need your help

i have developed Custom Reporting item , i have make simple user control and sure it is done in win form , and then i took this control and have made design time component and run time component and i deploy me item,and it appear in report item toolbox , but when i tried to drag this control in the report there is an error appear : the method or operation is not implemented

please can any one tell me what is the cause of this error

best regards,

Sounds like something in the in the Constructor trying to do it's job before the item is loaded.

Can you move code from the constructor to the Load event?

If you have custom/override on the On_Paint event, that could also be a source of the problem.

re: question about CRI

Dear tlhintoq :

thanks for your fast reply , actually my constructor dont' do job excpet intilze varabile , and about on paint event could you please explain in more detial what do you mean by this cause

this is my design time class

    public class mapDesigner : CustomReportItemDesigner
    {
        private mapControl map_control;
        private DesignerVerbCollection _verbs;

        public mapDesigner()
        {
            map_control = new mapControl();
        }

        public override void InitializeNewComponent()
        {
            SetDefaults();
        }

       public void SetDefaults()
        {
           // intial values 
            Microsoft.ReportDesigner.Drawing.ReportColor outlineColor = new Microsoft.ReportDesigner.Drawing.ReportColor();
            outlineColor.ColorRgb = Color.Black;
            this.Style.BorderColor.Default = outlineColor; 
           Microsoft.ReportDesigner.Drawing.ReportColor barColor = new Microsoft.ReportDesigner.Drawing.ReportColor();
           barColor.ColorRgb = Color.Green;
           this.Style.Color = barColor;
           IComponentChangeService changeSvc = (IComponentChangeService)this.Site.GetService(typeof(IComponentChangeService));
           changeSvc.OnComponentChanged(this, null, null, null);
        }

         // OVERIDE METHODS
         // override onpaint 
       public override void OnPaint(PaintEventArgs e)
       {
            // give control some values
           map_control.FillColor= this.Style.BorderColor.Default.ColorRgb;
           map_control.Height = this.Height.Pixels;
           map_control.Width = this.Width.Pixels;
           map_control.DrawControl(e.Graphics);
       }

         // override default size
       public override Microsoft.ReportDesigner.Drawing.DesignSize DefaultSize
       {
           get
           {
               return new Microsoft.ReportDesigner.Drawing.DesignSize(new RSDrawing.Unit(150),new RSDrawing.Unit(30));
           }
       }

       public override Adornment Adornment { get { throw new NotImplementedException(); } }
       public override DesignerVerbCollection Verbs
       {
           get
           {
               if (_verbs == null)
               {
                   _verbs = new DesignerVerbCollection();
                   _verbs.Add(new DesignerVerb("Reset Defaults", new EventHandler(OnCustomAction)));
               }

               return _verbs;
           }
       }

       private void OnCustomAction(object sender, EventArgs e)
       {
           switch (((System.ComponentModel.Design.DesignerVerb)sender).Text)
           {
               case "Reset Defaults": SetDefaults(); Invalidate(); break;
               default: MessageBox.Show("Not supported"); break;

           }
       }


        //
       public override void BeginEdit() { }
       public override void Dispose() { }
       protected override void Dispose(bool disposing) { }
       public override void DoDefaultAction() { }
       public override void EndEdit() { }
       public override void OnBackgroundColorChanged() { }
       public override void OnColorChanged() { }
       public override void OnDragDrop(DragEventArgs e) { }

       public override bool ShowContextMenu(int x, int y) 
       {
           return true;
       }
    }

hint : i override all these methods cause they are virtual in parent class (do i have to do so???)

and this is my run time class :

public class mapRender : ICustomReportItem 
    {

       private CustomReportItem _cri;
        private Microsoft.ReportingServices.ReportRendering.Image _image;

        }

       // Initialize

       private void Initialize()
       {
           if (null == _progress)
           {

           }

          }
      }

    public ChangeType Process_public()
       {
           // initialize CRI from properies in RDL
           Initialize();

           // create a memory stream to save the image

           _image.MIMEType = "image/bmp";

           // serialize the image stream into the RS image
           _image.ImageData = stream.ToArray();

           _image.Sizing = Microsoft.ReportingServices.ReportRendering.Image.Sizings.AutoSize;

           return ChangeType.None;
       }

    Action ICustomReportItem.Action
    {
        get { return Action_public; }
    }

    CustomReportItem ICustomReportItem.CustomItem
    {
        set
        {
            _cri = value;
        }
    }

    ChangeType ICustomReportItem.Process()
    {
        return Process_public();
    }

    ReportItem ICustomReportItem.RenderItem
    {
        get { return RenderItem_public; }
    }

    }

can you please tell me if i have problem on this implementation

TIP: When you first created your question you were asked to wrap your code with [code] tags.

[imgnothumb]http://files.me.com/tlhintoq/10jihf[/imgnothumb]

It really does help a bunch. Look how much easier it is to read now that someone has done it for you. Its the button with a '#' on it. [imgnothumb]http://clint.stlaurent .net/bytes/tags-code.jpg[/imgnothumb]More on tags. They're cool. Check'em out.

[tlhintoq]

Personally, I wouldn't do this

 map_control.Height = this.Height.Pixels;
           map_control.Width = this.Width.Pixels;

in the OnPaint. It means you are sizing every time the control is painted. I would put it in the SizeChangeCompl eted event. So when your parent control is resized, so is the encapsulated child control... but not every time it is painted.

Things like this can cause a problem with the designer. As soon as the designer tries to paint this control, your OnPaint override is executed. But if 'this' doesn't exist... then you cannot do this.width .. and so on.

See how this trickles down?

i have done that

[saraMoghazy]

i have done that

but stil the same error appear

[tlhintoq]

public mapDesigner()
        {
            map_control = new mapControl();
        }

Just as a test, comment out this part. Don't make the mapControl when you make the Designer.

I've had this be a problem in a few cases when I nested one control inside another. The constructor for the nested control had some issue because it couldn't find a DLL it was dependent on in the new parent project and so on.

i have done it , the same error appear when i drag the control to report layout , do you think this may be problem in deployment , let me say my steps in deploy :

1- i have copy the CRI dll to 2 folders

C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\P rivateAssemblie s

&&

C:\Program Files\Microsoft SQL Server\MSRS10.M SSQLSERVER\Repo rting Services\Report Server\bin

2- i have copy in the RSReportDesigne r this

 <ReportItems>
		  <ReportItem Name="mapControl" Type="MapCRI.mapRender,MapCRI"/>
	  </ReportItems>


	  <ReportItemDesigner>
		  <ReportItem Name="mapControl" Type="MapCRI.mapDesigner,MapCRI"/>

where MapCRI is the namespace and mapDesigner , mapRender classes inside this solution

3- copy in rsreportserver this :

<ReportItem Name="mapControl" Type="MapCRI.mapRender,MapCRI"/>

in
in rssrvpolicy

<CodeGroup class="UnionCod eGroup" version="1" Name="CRICodeGr oup" Description="Co de group for the ProgressTracker CRI" PermissionSetNa me="FullTrust" >
<IMembershipCon dition class="UrlMembe rshipCondition" version="1"
Url="C:\Program Files\Microsoft SQL Server\MSRS10.S QLSERVER2008\Re porting Services\Report Server\bin\MapC RI.dll"/>

is that the compelete deploy
