Forms Data Controls :: Unrecognized Namespace System.Web.UI.DataVisualization.Charting?
Feb 10, 2011
I'm getting a warning in my page directives saying that this namespaceystem.Web.UI.DataVisualization.Charting isn't found. I went to add a reference to the project so I could import the namespace and this namespace does not exist in the .NET tab. What do I need to do to get this working? Also, even if I add this to my Global Assembly Cache, that won't do anything for the web host web server that my website is publically on.Any guidance on this? How to get it on my local machine as well as understanding that it'll work on the actual web server?
I have a report like page which displays a gridview and a chart created from .Web.UI.DataVisualization.Charting which I want to convert to pdf. Currently I am using iTextSharp which in my opinion is really great. I managed to create the table in the pdf but cannot find a way how to display the chart as well.
I'm using MonoDevelop on Mac OS X Snow Leopard to develop an ASP.NET MVC Application. I have tested it on Visual Studio 2008 on Windows 7 and it worked fine, but when compiling it on MonoDevelop it throws the error: The type or namespace name 'Objects' does not exist in the namespace 'System.Data' under this line: public partial class MoviesDBEntities : global::System.Data.Objects.ObjectContext
I am getting a strange error over one site vs another. I have created a chart web site that works, but now I'm moving that code into an existing website. I'm getting this error (see title) and cannot figure out why. The references are the same and I have the using directives the same (as far as I can tell). I'm stumped.

I would note that I updated to VWD Express 2010 then had to revert back to 3.5 because my host at Arvixe had not updated my server yet. He then said he updated it and I reverted up to 4.0 again. It turned out he hadn't and I tried to revert back...and then this showed up and numerous other errors.

As you see above , we have more data in pie chart to plot and hence 3 DOTS appear at right bottom. Hence user cant see all the legends.Is it possible to have.say a tooltip on 3 DOTS so that when an user hovers,he sees entire / remaining legend list?
i doing one application.That is grid binding .i got this error
System.Web.Mvc.HtmlHelper<object>' does not contain a definition for 'GridView' and the best extension method overload 'MvcApplication2.Code.GridViewExtensions.GridView<T>(System.Web.Mvc.HtmlHelper, MvcApplication2.Code.GridViewData<T>, System.Action<MvcApplication2.Code.GridViewData<T>>, System.Action<T,string>, string, string, System.Action<T>, System.Action<MvcApplication2.Code.GridViewData<T>>)'
how to find this solution and how to change System.Web.Mvc.ViewPage to System.Web.Mvc.ViewPage<Model>
I am looking for a charting tool to generate charts in my ASP.Net page which will allow me to customize the charts to a great extent like changing the background of chart, specfying custom x and y axis and much more.Moreover, another major requirement is that the chart should be interactive enough. I would like to select data points on my chart, select a range of data points on charts by making a selction with mouse clicks and use these selections for further processing.
I am plotting a chart using charting control. The x-values are text values and y values are date values.
If there is same text multiple times, then the plotted chart has multiple bars of same value. I want the values for the same text to be on the same bar.
I am making a chart on a asp.net page (visual studio 2010). I am "summing" time. As long as the sum is not more than 24hours, all goes well. But if the sum is bigger than 24hours, then I get a "Not a legal Oleaut date" error.
This is my code (simplified) :
Chart1.DataBindCrossTable(_dataset._table.AsEnumerable(), "factor", "week", "time", ""); Chart1.Series[0].YValueType = ChartValueType.Time; duurhhmm is a DateTime field. "factor" and "week" are my groupings for the x-axis.
first question : what to do about the "not a legal oleaut date" ?
second question : on the axis I see 00:00,06:00, 12:00,18:00 and then again 00:00,06:00, etc... But I would like to have 24:00, 30:00.
i´m creating a webpage as a project to school. In this project i´m dynamically adding data to Placeholder (PH1). Is possible to send all the content from PH1 by using namespace System.Net.Mail?
in mscorlib.dll assembly with "System" namespace present ,why it was necessery to take the same name "System" for a assembly System.dll ? Is there any relation in choosing the same name ?
This may seem like a really simple question, but can I use the System.Threading namespace in ASP.NET web forms? I have a web page which uses HTTP GET/POST to gather page customisations (title, subtitle, etc.) from the user and numerical input which is passed to a ASMX web service. Currently they work sequentially, the customisation first followed by numerical processing. So can I use threading to do this?
I am using MS Chart control (3.5), and have a requirement where I need to display 2 pie charts. The datapoints for the pie charts is set programatically. My doubts are as follows:
1. Can I display both the pie charts in a single chart control and area, or do I have to use two controls? (Currently I am using two controls)
2. How can I maintain the same size for both the pie charts? This is my main concern, since the pie sizes keep changing, depending on the number of datapoints. I tried using custom properties like "MinimumRelativePieSize", but it's not working.
