I've created a website that allows users to register, log in, create tasks, be added to tasks. I want to the user to be able to add hours to these tasks, for a summary page that will contain a chart. I want to store all previous hours worked on the task so that the user will be able to view a chart on progress of the tasks? What would be the best way to go about implementing this? I'm using VB.

I am creating an Asp.net web site which will support dynamic data. When I am creating a dynamic web site from Scratch (from template in VS) all is working fine. But when I am trying to add dynamic entity (.edmx) file and running the application I am getting following error

We are building a financial web application which requires a real time chart. Initially an empty chart will be shown to the customer with X-Axis from 08:00 to 18:00 with a gap of 2 hours, i.e 6 points. The Y-axis should be adjusted based on the price between these timings. Now, from 08:00 the client(browser) will send a JSON/Ajax request to the server for every 15sec(configurable time) to fetch the latest price. And then, the price needs to be updated on chart based on the time.
I have seen some third party controls but really aren't successfull to satisfy this requirement. Telerik controls doesn't have client side access to the chart because it renders as an image.

I want to create a chart with more than 50 000. Up-to-date I use the dotnetcharting-chart-library. But the problem is the time to load the chart. It needs more then 20 minutes. An unbelivable event.
I load the chart with the values directly from database. The database-query needs less than 10 seconds. The rest of time the chart was created.
So my question to you. Do anybody know a chart-library for ASP.NET C# to show more than 50 000 measurements in one diagramm in a realistic time for a webuser.
I remember seeing an example explaining how you could setup the asp.net chart control to show two sets of data from different date ranges on the same chart, but I can't find it now that i need it.It showed sales for Jan, Feb Mar 2009 in one series and sales for Jan, Feb, Mar 2008 in another series and had the chart in 3D so that one series was in front of another.Does anyone know of such an example or have any pointers how to achieve it?
View 1 RepliesI am having trouble displaying a stacked bar chart with a Y-Value of 1.
See the mark-up below: The first Y-Value of the first series (the RED series) is 1. The first YValue of second series (the BLUE series) is also 1. The chart only shows the blue series. If I swap them around in the mark-up it only shows the red.
The last value (when X is 6) is 2 for both series. The charts will show both colors for the value of two. I would like this behavior when the value is 1.

Explaination in detail I have a tree view control on left of my page and AjaxToolkit:TabContainer on the right,consisting of 9 tabs in it (I have developed individual controls and added to the tab panels). On selecting a value from the tree view control the I am refreshing the values inside all the tab panels. There is a method reload written on all the controls which are called on tree view click which sets the value of the selected tree item in properties in all the controls and also refreshs them. Its a big performance issue for sure which i need to improve on but that would come later.
My problem
1. In the Main tab (ascx control) consists of asp:chart control which I am populating and it also consists of 2 buttons in which ModalPopupExtender would open up another 2 controls on button click within this control. Now on the tree view click I am calling
the reload of Main Tab which internally called the reload function of these 2 controls also
On Tree view click
Maintab.reload
{
ModalPopupExtender1.reload
ModalPopupExtender2.reload
}
Secondtab.reload
Thirdtab.reload
If I populate the asp.chartcontrol without reloading the ModalPopupExtender1.reload ModalPopupExtender2.reload it works great but when I call both ModalPopupExtender1.reload
ModalPopupExtender2.reload it shows up and goes away.
Any thing i am missing on ? How to make chart control stay on the page and not vanish. I tried making it visible again. The main page contains a chart control which comes and goes away and does not stay only if i comment out the reloading of these usercontrols it stays visible with values on the main page else goes away.
2.Performance problem- I am not sure how to lazy load the content inside the tab panels so that controls should have the selected item for tree view click and can populate thereon.
3. This is how I call my user controls to reload on the treeview click from within the main page.

How to use Chart control in visual web developer 2010?
View 7 RepliesI've just rebuilt my PC and have upgraded to visual web developer express 2010. I have imported my projects which use the charting control quite a bit. Unfortunately my projects are failing to run. In design view the control is now showing as "unknown server tag asp:chart". I can see the Chart control in the data tab in the toolbox but it is greyed out.

View 1 RepliesI like the way that the chart control seems to automatically determine the X axis range for me based on the data, but in this case, the data can only be whole numbers.
What is the easiest way to specify whole numbers for this axis?
when trying to start this in Visual Studio 2010 express I dont get any window of this tool. I wonder why, something seems to be happening as I see two new tray icons. But I cant change anything.

View 1 RepliesI have a Gridview that works and in one of the TemplateFeld EditItemField I have a checkboxlist that I dynamically create based on the row ID.

View 2 RepliesALL the server controls are not showing in Visual Studio ASP.net project. It used to be intermittent, I would restart devenv and they would show again(even if the layout was terrible) Anyhow now it's not showing at all. The only change I made to the project was to switch Membership providers to MySql. Even pages that have no reference to Membership don't display.Anything(page wise) that has a server control fails (displayes the message "hresult e_fail when creating com component") even if it's just a label with no programming logic.
