Install issues

I down loaded the reports MSi file for Q2 2009 and ran the install.

I now have a Section in my toolbok listing Telerik Preporting Q2 2009 with 3 object in it: pointer, ReportBookControl, and ReportViewer but none of the tools shown in the demo. Nor do I have the Telerin Reporting item in the menu bar but I do have the Telerik menu iteem for the ASP.NET tools.

Is there something else I need to do to get these?

Legend Series Name

How do I change the name of the series programmatically for display in the legend? (Chart Object)

I have this as my needdatasource event and every time I try to hit series(0) I get index out of range errors. I have a datatable that always returns 3 columns of label, x, y and need to name x and y to what the user selects. (x = sales, y =volume). I have seen a number of examples, and tried them, but to no avail.

    
                Private Sub Chart1_NeedDataSource(ByVal sender As Object, ByVal e As EventArgs) Handles Chart1.NeedDataSource 
        
                    Dim chart As Telerik.Reporting.Processing.Chart = TryCast(sender, Telerik.Reporting.Processing.Chart) 
        
                    Dim mydt As DataTable 
        
                    mydt = GetDTNoQ() 
        
                    Dim mycount As Int32 = CInt(mydt.Rows.Count / 8) 
        
                    Chart1.PlotArea.XAxis.LabelStep = mycount 
        
                    chart.DataSource = mydt 
        
                    'Dim mySeries As Telerik.Reporting.Charting.ChartSeries = Chart1.Series.GetSeries(0) 
        
                    'mySeries.Name = "Sales" 
        
                End Sub

Sessionstate = SQLServer, Reporting, parameters

Hi,

I changed my web project over to using a state server rather than inProc e.g.

sessionState

mode="SQLServer"

Once I implemented this my parametered reports failed, ok not too much of a problem I thought, I will use parameters to pass the information into the report, and use the NeedDataSource event to collect the correct data, this has worked for everything that is bound to controls, but on a lot of my reports I programmically set the Values of some of the text boxes, this cannot be done within the NeedDataSource event because at this point the textboxes are already set (I think?),

so in the past I was able to do the following

this.txtCompany.Value ='this is a test'

in the constructor, but this now does not work because this work is now done in the NeedDataSource event, so I have tried the following

Telerik.Reporting.Processing.TextBox MyCompany = (Telerik.Reporting.Processing.TextBox)txtCompany;

MyCompany.Text = 'this is a test'

;

of course the Telerik.Reporting.Processing.TextBox is different to Telerik.Reporting.TextBox so it does not work.

does anyone have a solution to this problem, specifically programmically assigning values to textboxes on reports in any event after the constructor, I have maybe 20 textboxes on each report so setting an event for each textbox would be slow.

thanks in adavnce.

World is not Supported?

Everything works okay in Q12009, however, after I upgraded to Q2, I got "World is not Supported" error, just seeking for any suggestions.

I use the following code to generate and preview the report

    
            Dim reportType As Type = Type.[GetType](String.Format("AgentLive.{0}, AgentLive, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null", reportName))  
        
            Dim report As IReportDocument = DirectCast(Activator.CreateInstance(reportType), IReportDocument)  
        
            Me.ReportViewer1.Report = report

And at report code-behind

    
             Private Sub dbReport_NeedDataSource(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.NeedDataSource  
        
                    Dim report As Telerik.Reporting.Processing.Report = DirectCast(sender, Telerik.Reporting.Processing.Report)  
        
                    report.DataSource = PrepareDBRPT(dbSource)  
        
                End Sub 
        
              Private Sub detail_ItemDataBound(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles detail.ItemDataBound  
        
                    Dim detail As Telerik.Reporting.Processing.DetailSection = DirectCast(sender, Telerik.Reporting.Processing.DetailSection)  
        
                    Dim section As Processing.DetailSection = TryCast(sender, Processing.DetailSection)  
        
            'Customize something  
        
                End Sub

[Solved] DataSet does not support System.Nullable<>

We've been using Telerik Reporting with a product that we have been developing for about a year. We have designed 5 or 6 reports for that product over the past several months using Q3 2008 SP1. These reports are bound to business objects that we have designed to work with NHibernate.

Today after upgrading to Q1 2009 we now get this error at design time on any report bound to an object with a nullable type such as:

'int?'

Our objects have had nullable types for quite some time now and we have never had any problems. We are excited about the new Table and Crosstab controls that were introduced with Q1 2009 and are looking forward to using them, but we must be able to bind to our business objects at design time and they must include nullable data types.

How to dynamicly add a summary banner by testing each added Item

Hi,

I need to find out if there is some way for me to do checks in my report when it is generated. Currently I'm generating a report that receives a collection of objects as its datasource(via a bindingsource). Each of these objects in my collection is of type ITenderLineItem. This is an interface that I wrote. So basicly this list contains objects of different datatypes. They are: TenderSeries, TenderSection and TenderItem. All three these classes implements ITenderLineItem. Now in my report I'd like to display:

Series/Section Nr	Item Nr	Description	Unit	Qty	Rate 1	Amount 1	Rate 2

1000		General			0		0 --> Series
1000		Section 1			0		0
	10.1	Item 1			1000		1000
	10.1	SubItem 1			2000		3000
Summary Here	(i)	SubSubItem 1	mm2	5	4000		7000
2000		Housing			0		0 --> Series
2100		Section 1			0		0
	21.1	Item 1	UNIT	100	0		0
	(i)	SubItem 1			0		0
	(i)	Sub-SubItem 1			0		0

Summary Here

But at the moment I'm just getting my report to display all Items:

Series/Section Nr	Item Nr	Description	Unit	Qty	Rate 1	Amount 1	Rate 2

1000		General			0		0
1000		Section 1			0		0
	10.1	Item 1			1000		1000
	10.1	SubItem 1			2000		3000
	(i)	SubSubItem 1	mm2	5	4000		7000
2000		Housing			0		0
2100		Section 1			0		0
	21.1	Item 1	UNIT	100	0		0
	(i)	SubItem 1			0		0
	(i)	Sub-SubItem 1			0		0

The way I see it is that I'd need to have some sort of check in my report to determine if the Item being added is a Series Item and then to insert a summary section to summarize the totals per series etc. This I can do by castig the object or calling the ToString() method and checking what gets returned. Problem is I don't know how to do this sort of testing in my report. What events should I use and what expressions do I need to add to my TextBoxes.

Regards

Jacobus

        Me.SqlDataAdapter1.SelectCommand.Parameters("@EndEffDate").Value = Me.ReportParameters("@EndEffDate").Value

Dim dataSet As New DataSet()
SqlDataAdapter1.Fill(dataSet)

        Dim ChartInc As Telerik.Reporting.Processing.Chart = CType(sender, Telerik.Reporting.Processing.Chart)
        Dim DefChart As Telerik.Reporting.Chart = DirectCast(ChartInc.ItemDefinition, Telerik.Reporting.Chart)
        ChartInc.DataSource = dataSet

I am trying to have 2 different charts: one showing TotalIncurred and one showing ClaimCount as the series. I want to show them by Policy Year and by Line on the same chart, but group them. I thought I could use the DataGroupColumn, so I tried

setting PlotArea->XAxis->DataLabelsColumn to PolicyYear and DataGroupColumn to Line. It isn't working. Any ideas on how to do this?

Step 1, i create a new class lib
step 2, i add a new item of type Telerik report 2009 Q1
when the design view comes up i get

To prevent possible data loss before loading the designer, the following errors must be resolved:

No data in Design Preview

If the table adapter in dataset use connection string stored in Web.config, the report works OK when running the web page but show no data while previewing in Design mode.

I tried the solution proposed in forums but didn't work.

    
                        ConnectionStringSettings connSettings = ConfigurationManager.ConnectionStrings["myConnectionString"]; 
        
                        if ((connSettings != null) && (connSettings.ConnectionString != null)) 
        
                        { 
        
                            this.hospitalDataSetTableAdapter1.Connection.ConnectionString = ConfigurationManager.ConnectionStrings["myConnectionString"].ConnectionString; 
        
                        }

I debug Design Preview with a MessageBox like this...

    
                        } 
        
                        catch (System.Exception ex) 
        
                        { 
        
                            // An error has occurred while filling the data set. Please check the exception for more information. 
        
                            MessageBox.Show(ex.Message); 
        
                            System.Diagnostics.Debug.WriteLine(ex.Message); 
        
                        }

and I get "Object not set to an instance of an object"

What am I missing?
Thanks a lot!
