Forms Data Controls :: Creating New Instance Of Chart Displayed In Table
May 5, 2010
I am building a .net page and need to display some data residing in a database. Some of it's working, some not. I would like to use a table to display the data with the format below..
Table
row - question data
row - answer (count)
row - next answer (count)
row - BarChart representing the answer counts for question
row - next question data
row - answer (count)
row - next answer (count)
row - BarChart representing the answer counts for question
The question data and answer count rows are generated with no issue. However, the rows containing the barchart are problematic. Not sure how to create a new instance of a chart on the fly and hook in all the methods, etc. and get the control added to and displayed in the tablecell. Been looking for examples to create the chart on the fly with no real results.
I am stuck in chart controls...Here is my prob... There is a ListBox containing some items...when user selects multiple items from the list box I want to generate a dynamic table with the number of columns same as that of the number items selected in the listbox. And for each selected item I want to show a seperate chart in the columns...Currently I want the same chart control for every selected item (i.e. a static hard coded chart that i will replace later by dynamic values)....I am using a method that draws a chart control using a sample dataset... I am calling it each time when a new column is created..Also the DrawChart method executes for the first column only and throws an index out of range exception! after the first execution...my code is not working...here
i'm trying to create a stacked bar chart on a vb web form using vs2010.My data source returns:
Error in Functionality Awaiting on Supplier
1IMT IssuesmActive6
IMT Issues,Awaiting on Supplier
2,IMT Issues,Awaiting on User 4
IMT Issues Closed 120
Login / Password Active
But I can't get this into a stacked chart. I know I must have to do quite a bit of work declaring what the series are and soforth, or having a different dataset but can't find any documentation on it.A link to some documentation or an example of a stacked chart from an sql datasource would be much appreciated.
I am trying to create a chart with three x-axis labels where the chart series x-value member is a date. That is, each data point is a day returned from a SQL Server table. The first label row is to be the day component, the second label row the month name component and the third label row the year. The returned dataset can be from any time period and of varying length. It needs to look like below so each day can be seen but the bigger picture is also shown.
x-axis label(0): 26 27 28 29 30 31 1 2 3 4 5 6
x-axis label(1): March April
x-axis label(2): 2010
I can set the first row using the design time properties as such
[Code]....
I am not sure how to create the next to custom labels at runtime. I have gone through the options using Add(Double, DateTimeIntervalType, Double, Double, String, Int32, LabelMarkStyle) and Add(Double, DateTimeIntervalType, String, Int32, LabelMarkStyle) but I just cannot get them to appear in the chart label.
I tried the other method [Code]....
however could not find how to set the DateTimeIntervalType on the CustomLabel object.
There was nothing in the ChartSamples and I am not even sure if it can be done.
I have what is turning out to be a rather complicated issue - at least for me.
I have a table with TeamID, TeamName, TotalTeamSize, ArrivalDate adn DepartureDate.
I need to create a source for a bar chart that will show the number of people deployed each month. It can be assumed that the entire team is dployed for each of the days between the ArrivalDate and the DepartureDate. Sometimes the ArrivalDate/DepartureDate spans two months (very rarely more) and sometimes it does not.
Here is what I have so far. In this setup phase, I thought I'd get the code working for one team (using a DropDownList) and then cycle through the entire table in order to get the full dataset for the bar chart.
i need to display a chart according to the table stored in the database,i have installed mschart,when i choose datasource it is working properly? can anybody give me the details how to put a chart?
apologies beforehand for what can possibly be a daft conceptual question. I have an ascx control that has a bunch of ASP labels and buttons in the ascx page and some other public methods and properties in the code behind. When I drop this ascx control in a page it all works fine. I now have a page with a placeholder and I am trying to dynamically create an instance of my ascx control and put it there. I then reference this control in code and while all public methods and properties are available (ie MyControl.TitleString = "Hello";MyControl.DoSomething();) none of the ASP controls are. Rather, they are all null. So MyControl.buttonSave is null, MyControl.LabelTitle is null, etc. Is this by design? Am I missing something? If not, what's the point of being able to create dynamically do this?
I am using asp.net charts in my application, i have given the axis values from code behind. I added the on page load but the problem when i go directly to that page the graph will not appear but if i reload the same page it will appeare. this happens when i publish the application and try on IIS, but there is no problem before publish (while run in VS).
I'm a bit of an ASP.NET newbie and I am creating a data table in memory and binding this to a gridview control. The code is as follows:
Dim DstBasket As New DataSet, TblBasket As New DataTable With TblBasket .Columns.Add("BskPrdCd", System.Type.GetType("System.String")) .Columns.Add("BskPrdDesc", System.Type.GetType("System.String")) .Columns.Add("BskQty", System.Type.GetType("System.Int16")) .LoadDataRow(Split("12345,Test product 1,1", ","), True) .LoadDataRow(Split("122,Test product 2,2", ","), True) .LoadDataRow(Split("123A,Test product 3,5", ","), True) .LoadDataRow(Split("44,Test product 4,1", ","), True) End With DstBasket.Tables.Add(TblBasket) With LfnGridView("GdvBasket") .DataSource = DstBasket .DataBind() End With
The data displays in the gridview control fine with both edit & delete options but when I attempt to delete, it has no effect. How do I force removal of the relevant row from both gridview and table? Most of the documentation I have unearthed shows how to achieve this when connected to a SQL table which is clearly not the case here.
I have an issue in using dot net chart control. In chart last column is not completely shown which give bad appearance and on right side of chart it looks like TickMark are enabled. I set MajorTickMark of AxisY2 disabled but still tick marks on right side.
I have a drop downlist,and next to it there is an MS bar chart.i want to change the datate of the MS chart ,once the user selects another year from the dropdownlist.
When the page loads ,the chart displays the default year(2011) and it works.The problem is that is does not change the data when you select another year from the dropdownlist.
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.
I started using the awesome chart controls with my asp.net apps recently and so far they've been nothing short of breath taking. Right now I have a weird problem, on the first load of my page, the chart control appears correctly and the tooltip is correct, however, when I update it with new data, the chart displays correctly, but the tooltips are for the previous set of data.
I hope this makes sense. The first time I load the chart, the pie chart segments and tooltips are correct, after a partial postback (to get the new data), the pie chart segments are correct but the tooltips are for the previous data set.
Basically once the tooltips are set the first time, they can't be updated after that without a full page postback.
Here's how I set the tooltip:
[Code]....
Anyone else noticed this behaviour and have a work around?
Currently my only workaround is to check for a partial postback and not render the tooltip, which I'd rather not do as the tooltip display actual statistical data as opposed to the pie itself (which uses percentages).
I want to make a bar chart from the google analytics data. Current implemetation of the bar chart in my site is by See Analytics I am developing an ASP.NET website and this See Analytics is using PHP and jQuery to conjure the chart. It is also paid. What my client would like is a similar tool that draws chart from analytics, without a PHP Component in it. ie. A similar tool using ASP.NET and jQuery/javascript. What I would like is to get that tool for free(open source).
i've got a project requirement in which a webpage developed in asp.net+C# - (used for information gathering from the end user) can be changed to a report view of the same page (after submitting) with dynamic html formatting without affecting the original page can it be done by creating an object of that webpage and modifying its properties or creating an instance of the page or something like that.
im trying to build two charts from a sql query. this is the table i have.
table name services in sql server 2005, with some fields like.
service name categorie creation date status, (status here is boolean, true when the service is finished and false when the service is pending)
this is the interfase i got so far:
and ill place two chart pies below this image, to display charts dependin on the selections.
one chart should display the count of services from the selected categorie in the dropdownlist in relation to the dates selected in those textboxes and if no categorie is selected, it would display the total of services in each categorie in the first pie webchart,
and the other pie webchart should display the number of services that are finished or pending according to the selected categorie in the dropdownlist and the date range especified.
but the problem is that i dont know how to count in the sql query and assign the results to the charts.
I am dynamically creating initial rows and cells in a asp:table on Page Load, whose cells need to have embedded user controls.
I have an Add Row button, where in, whenever I click I need to add rows to existing table and also persist viewstate of the user controls already added earlier to cells during initialization.
When I click on Add button, the controls disappear. how to recreate tables with their embedded user controls and populate the viewstate.
This is the basic piece of code I have currently and I am stuck -
