Hello,

I'm using the trial version and trying to find out if Telerik Reporting is right for me. For the most part it's seemed like an excellent choice, but I do have one issue that I haven't been able to figure out.

For the most part, my binding will be to business objects. One item that often comes up in my business objects is a generic list of IP Addresses (System.Net.IPAddress). When I try to do this, I get a red box on my report that says

"An error has occured while processing TextBox 'TextBox1':
The expression contains object 'Item' that is not defined in the current context.

Textbox1 is within the details section, and the details section is the only section on the report.

To test this, I created a class called Addresses in 3 different ways, and used this code in my report's constructor:

Then I tried 3 different versions of the Addresses() class.

Version 1:
This produced the error above.

Version 2:
I tried the list as a string, just because that's how all the samples I saw on the site are. This produced the expected results of a nicely formatted list of IP Addresses. However, my business objects do not have the IP Addresses as Strings, they are System.Net.IPAddress objects. I just tried this one for proof of concept.

Version 3:
I tried this to to see if an IP Address as a property would render properly on the report, and it did.

With all 3 versions, I left the constructor the same way, and the textbox in the details section. It seems that as a standard property, the System.Net.IPAddress object could be rendered properly, and it also seemed that Telerik Reporting can understand a generic list, however, when I combine the two, it does not seem that Telerik Reporting can understand a Generic List of System.Net.IPAddress objects. Is this correct, or is there another method I am missing?

As an aside, if you are not familiar with System.Net.IPAddress, the familiar format of an IP address (ex. 192.168.0.1) is returned with the .ToString() method. It does not have a property to return it.

Thanks for any help you can give.

I dont know what I have done wrong. I have a chart, the chart needs a datasource. This is my NeedDataSource-method

private

 

void companyBooking_NeedDataSource(object sender, System.EventArgs e)

 

{

Telerik.Reporting.Processing.

Chart companyBookingChart = sender as Telerik.Reporting.Processing.Chart;

 

companyBookingChart.DataSource =

this.bokadoktornDataSetTableAdapter1.GetData();

 

}

In the InitializeComponent()-method I have this eventHandler.
this.companyBookingChart.NeedDataSource += new System.EventHandler(this.companyBooking_NeedDataSource);

This is my database-sqlquery, (Works fine)

SELECT YEAR(BookedDate) AS Year, MONTH(BookedDate) AS Month, CONCAT(u.FirstName, ' ', u.LastName) AS FullName, Count(*) AS NoOfBookings
FROM         Bookings b
INNER JOIN Users u ON u.Id = b.BookedById
INNER JOIN CompanyUsers cu ON cu.Id = u.Id
WHERE cu.CompanyId = 1
GROUP BY u.Id, MONTH(BookedDate), YEAR(BookedDate)
ORDER BY NoOfBookings DESC;

When I preview my report nothing happends. I dont know why, everything worked fine until I added my chart. Is it something wrong with my NeedDataSource-method.

Thanks

Hi
In a textbox in detail section, i have to display either low or medium or high based upon the value of another textbox(in detail section), which takes value from the database. Where should i write the if condition statements?

Hey folks,

I got a weird and annoying problem here in my report:

When using a CheckBox element in a Telerik Report it alway appears blue in color. To avoid that, I decided to create my own icons for CheckedImage and UncheckedImage. Unfortunately I can't attach this gifs to this post. But they are just squares with a border of 1px and a widht/height of 13px. The checked one is just a filled square.

But whatever I do - in mein PDF Export. The icon is a little bit bigger than the original one. An ugly effect is then, that my square has either a 2px border on the left, on the right, on top OR at the bottom, which doesn't look nice on the screen and on a printed out document.

What am I doing wrong?

Thanks in advance

In the help file (Telerik_Reporting_2009_2_701_manual.chm) you say that "All exporting format extensions and the data processing are part of Telerik.Reporting.Processing.dll" However in the KB (http://www.telerik.com/support/kb/reporting/general/deploying-telerik-reporting.aspx) you do not mention that file.

I have a previous version running.
 -- What old Telerik dlls can I remove from the references?
 -- What references do I need to deploy the Q2 2009 reports in win forms?

Thanks,

Hi,
I was testing the latest build (3.1.9.807) for the medium trust support with this code:


But I'm getting security exception:

Hi,

I have a StackedBar100 chart in my report, everything works fine, but the problem is the appereance of the percentage result in the Bar.
For example: If I have a bar divided in two or more... the first value appears in the botton of the second part of bar and the other value appears in the top of the second part of the bar. I'd like to see each value appearing inside the correct bar.
Is that possible??

Another Question: I think this code is not good... maybe there is an easy way to do that with the same result.. isnt there??

Thanks...

Code:


    DataTable GetData()
        {
            DataTable dataTable = new DataTable();
            dataTable.Columns.Add("Descricao", typeof(string));
            dataTable.Columns.Add("Qtd1", typeof(int));
            dataTable.Columns.Add("Qtd2", typeof(int));
            dataTable.Rows.Add(new object[] { "A", 3, 5 });
            dataTable.Rows.Add(new object[] { "B", 2, 5 });
            dataTable.Rows.Add(new object[] { "C", 5, 5 });
            return dataTable;
        }


    private void chart2_NeedDataSource(object sender, EventArgs e)
        {
            try
            {
                DataTable dt = new DataTable();
                dt = GetData();


                Telerik.Reporting.Processing.Chart chart = sender as Telerik.Reporting.Processing.Chart;
                chart2.Series.Clear();
                
                ChartSeries s = null;

                for (int i = 0; i < dt.Columns.Count -1; i++)
                {
                    s = new ChartSeries();
                    s.Type = ChartSeriesType.StackedBar100;
                    s.Appearance.LegendDisplayMode = ChartSeriesLegendDisplayMode.Nothing;
                    s.DefaultLabelValue = "#%";
                    
                    
                    chart2.Series.Add(s);

                    foreach (DataRow row in dt.Rows)
                    {
                        ChartSeriesItem item = new ChartSeriesItem();
                        item.YValue = Convert.ToDouble(row[i+1]);
                        s.AddItem(item);

                    }
                    
                }

                foreach (DataRow row in dt.Rows)
                {
                    s.PlotArea.XAxis.AutoScale = false; //false permite gerar o xaxis com os valores que eu definir
                    s.PlotArea.XAxis.AddItem((string)row["Descricao"]);

                }


            }
            catch (Exception ex)
            {
                throw new Exception(ex.Message);
            }
        }

I need to include hyperlinks in my reports when they are rendered in the Web Viewer.  I'm currently using Q3 2008 and everything works fine.  I set the text of the textbox to include HTML like <a href="google.com">Click Me</a>.

I'm in the process of upgrading to Q1 2009, but it looks like my approach doesn't work anymore.  It seems the size of the textbox gets calculated based on the size of the text (including all the HTML code) so the textbox gets really large (even though when the browser processes the text, it's considerably smaller). 

So if I have a textbox who's Text is set to <a href="http://AReallyReallyReallyReallyReallyReallyLongLink.com">Q</a>, the textbox takes up a huge area but it ends up being only 1 characeter.

I thought I might be able to use the HtmlTextBox but it seems to completly ignore (and remove) hyperlinks.

Any suggestions?

Thanks,
-Stephen
