Hello!
I just update my reporting here, and It won't return the DataContext...
that was my code:

private ReportViewerModel Model

{

get { return DataContext as ReportViewerModel; }

}

I tried to use this code snippet, but still don't work, 'coz I calling the DataContext in a partial class who complements the ReportViewer class

var layoutRoot = (FrameworkElement)VisualTreeHelper.GetChild(this.ReportViewer1, 0);

var rvm = (ReportViewerModel)(layoutRoot.DataContext);

I need to call the DataContext to print my report.. I can see it, in reportviewer, but can't print...
There's something I can do?

Functionality like master - detail nested grid?

With the GRID asp.net component you can set up a nested grid so that each row in the master table has a nested detail table under it. I would like to reproduce this functionality in a report that is only intended for PDF output so no collapsing is necessary. This is for a assembly ticket that shows part kits to be assembled and their component parts. So it looks something like this

MASTER: Bin - Part Number - Description - Qty Ordered - Qty Backordered - UOM
MASTER: Bin - Part Number - Description - Qty Ordered - Qty Backordered - UOM
Detail:    Bin - Component Part - Quantity - UOM
Detail:    Bin - Component Part - Quantity - UOM
Detail:    Bin - Component Part - Quantity - UOM
MASTER: Bin - Part Number - Description - Qty Ordered - Qty Backordered - UOM
Detail:    Bin - Component Part - Quantity - UOM

Note that sometimes a part may not have any components, so nothing would need to be shown under those.

Ideally the master table and the detail tables would have separate datasources just like the GRID implementation.

Wish so may options (crosstabs, subreports etc... ) it's hard to get started down the right path. Can someone point me in the direction of a tutorial or sample of a solution of a solution for this?

Simple Grouped Output?!?!?!

I am becoming VERY frustrated with this reporting tool and the way it deals with grouping. The documentation is no help at all. It throws lots of concepts at you without really explaining what they mean.

What I want to do should really be very basic. This is a simple assembly output, with a master part, and then it's component parts. This should be the simplest type of group to produce yet I've been struggling with days on this and I am way past my deadline. PLEASE HELP.

Here is what I want:

PART NUMBER                                  QTY
ASSEMBLY_PART_NUMBER              1
COMPONENT_PART_1                      2
COMPONENT_PART_2                      3
ASSEMBLY_PART_NUMBER_2          2
COMPONENT_PART_1                      4
COMPONENT_PART_2                      6

Based on what I'm reading, I should be able to accomplish this easily with a table.

How I would expect it to work is:
The heading row is outside the group. The assembly part rows are the grouped row by the assembly part number, then the component part rows are a child detail group under the assembly part group.

This is not at all the behavior I am seeing. When I try to add parent and child groups it doesn't add a new row as I expect, it adds a new column, which just doesn't make any sense to me at all.

Please help me get on the right track with this!

Dynamic table creation

I guess I'm just lost as to how I can do this if it is even possible. I have my poco that I would like to bind to the datasource of the table. But I can't figure out how to create the table/crosstable layout to look like the attached image. The problem I'm facing is that I may have n approaches with each approach having n lengths. All approaches have the same number of lengths. Example, I have five approaches with 4 lengths each. From there I have a count for each hour for each approach/length.

Any help on how I can dynamically create the table?

Robert

Here is my model:

public class CrosstabClassificationModel

{

public class ApproachModel

{

public ApproachModel(List<int> lengthGroups)

{

Lengths = new List<LengthModel>();

int prev = 0;

foreach(int i in lengthGroups)

{

Lengths.Add(new LengthModel()

{

Min = prev,

Max = i

});

prev = i + 1;

}

public string Name

{

get;

set;

}

public ApproachTypes ApproachType

{

get;

set;

}

public List<LengthModel> Lengths

{

get;

private set;

}

public void Add(int length, DateTime time)

{

foreach(var l in Lengths)

{

if(length.IsBetween(l.Min, l.Max))

{

l.Add(time);

break;

}

public override string ToString()

{

return Name;

}

public class LengthModel

{

public LengthModel()

{

Events = new List<EventModel>();

}

public string Title

{

get

{

if(Max == int.MaxValue)

return string.Format("{0} and greater", Min);

else

return string.Format("{0} - {1}'", Min, Max);

}

internal int Min

{

get;

set;

}

internal int Max

{

get;

set;

}

public List<EventModel> Events

{

get;

private set;

}

internal void Add(DateTime time)

{

var @event = Events.FirstOrDefault(x => x.Time == time);

if(@event == null)

{

@event = new EventModel()

{

Count = 0,

Time = time

};

Events.Add(@event);

}

@event.Count++;

}

public override string ToString()

{

return Title;

}

public class EventModel

{

public DateTime Time

{

get;

set;

}

public int Count

{

get;

set;

}

public override string ToString()

{

return Time.ToShortTimeString() + " Total: " + Count.ToString();

}

public CrosstabClassificationModel()

{

Approaches = new List<ApproachModel>();

}

public DateTime Date

{

get;

set;

}

public List<ApproachModel> Approaches

{

get;

private set;

}

public ApproachModel this[string Name]

{

get

{

return Approaches.FirstOrDefault(x => x.Name == Name);

}

public override string ToString()

{

return Date.ToShortDateString();

}

404 from ReportService.svc using https and silverlight

Hello,
I went through many 'Enable SSL for Telerik Reporting WCF service' posts and articles. Still, when accessed through ReportViewer - ReportService.svc returns 404. If I use the same url in IE – it works.
I’m using 'reportViewer.ReportServiceClientFactory = this' and as soon as I create binding using: new BasicHttpBinding(BasicHttpSecurityMode.Transport) – I get this error.
Not sure where to look anymore… All other wcf services (same web app) do work with https.

Thanks,Sergey

Set Table column headings from DataTable column headings

I have created a Report in the Designer which contains a Table with a fixed number of columns. When I added the columns, it set the column heading to the default "string= same as the database field name". In the application, we create a DataTable object(called DetailsTable) populating the column headings from a resource file and the table rows with the data. The Report DataSource is set through the NeedDataSource event shown.

What I would like to know is what expression can I use to bring in the column headings from the DataTable object?
The objective is to remove all "hardcoded" strings from our reports.

private void table1_NeedDataSource_1(object sender, EventArgs e)

{

var objectDataSource = new ObjectDataSource();

objectDataSource.DataSource = ((BestFitStepDetailsReportView)this.DataSource).StepDetailsTable;

(sender as Processing.Table).DataSource = objectDataSource;

}

Report preview stops working after changing entity data model

I created a report using an EntityDataSource. Whenever I make a change to the model and rebuild the solution, my report previews no longer work. To get them to work, I have to close Visual Studio and reopen the project. Before restarting Visual Studio, here's the error message I get in the report preview:

The number of members in the conceptual type 'DataModelNS.ChangedEnityType'
does not match with the number of members on the object side type
'DataModelNS.ChangedEntityType'. Make sure the number of members are the
same.

javascript error in demo : unexpected token &

The demo Web viewer generates a javascript error in Chrome. Haven't tried IE yet. This error also occurs in my web app when I use the web forms viewer.

It doesn't seem to cause a problem showing the report, but it is still an error in the console none the less. The attached is a screen shot of the Chrome debugging console. This is the first pass through this function. There's a second pass through that succeeds with an actual valid URL to the .axd handler to, presumably, render the report in the iframe. However, why on the first pass are you trying to load the iframe from javascript:void(0);&RenderID= ?

Just to clarify, this is the demo c# solution, setting the WebDemo as the startup project.
