I have a gridview that I loop through to get the x and y values of the chart control, and upon the first execution of this code, it looks great. But when the page posts back and it "refreshes" data, the original points on the chart control are still there, as well as the new values.
Is there any way to "delete" all data in the chart control to ensure this doesn't happen?
I have two gridviews, say 'A' and 'B'...I want to add all the rows of 'A' to 'B' while avoiding the duplicates....For eg:

How does one go about removing the data labels from a pie chart with the new chart control in .net 4?
I can get these to display as tooltips absolutely fine, but ultiamtely I'd like the labels not to be present as it looks rather busy.
I've searched previous answers and seen code behind resolutions but surely there must be some sort of code infront option to turn these labels off?
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'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

IMT Issues,Awaiting on Supplier

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 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).

View 1 RepliesI've a form where I'd like to impede the user from entering any alphabits or special characters. The user can only enter numbers between 0 & 3( both inclusive) no more no less.
How can i achieve this ? I've used RangeValidator. Would this alone be suffice or do we also need to use Expression Validator ?
Here is what I've used :
<asp:RangeValidator ID="RangeValidator0" runat="server" ErrorMessage="Enter values between 0 & 3" ForeColor="Red" ControlToValidate="q1tb1" MinimumValue="0" MaximumValue="3" SetFocusOnError="true" Type="Integer"
ValidationGroup="rangeCheck">
I just want the focus to be in the same texbox if the user enters other than 0,1,2,3.

View 1 RepliesI have a simple .aspx page.
I want to show the data either in Chart control or Gridview control. When the user selects an option to see the data either in chart control or grid view control, that specific control has to show up and other control has to become invisible.
So far, I am able to populate data successfully in the chart control. If the user chooses "Grid view" option, how can I show the data in grid view control in the same location. I don't want the gridview control to be shown in a pop up window or any other window.
Is there a way to add a legend to the chart it creates? I have created a line chart and by default it has created different colors for the different y - axis data.
I would like a legend on the side that displays what data goes with which line color.
I'm using MS Chart Controls, i want to add a feature to my charts, im primarily using Bar charts. I will have a large numnber of Data points on my chart for example 20 bars etc, i want to limit the display to 10 so if there is more than 10 it will only show the last 10 bars and display a scrolling bar to scroll back and fort to see all the charts. I have the code to do this, and it works extremely well, only problem is. the code is in VB.NET I've converted it to C# and I am not getting any errors on page_load but my code doesnt seem to affect my chart in anyway, basically it doesnt work. Just wondering could some one have a look at my code and give me any pointers where i may have gone wrong or if anyone has ever got something similair to this working in c#. Im going to post both the VB.NET and the C#,

I am using a Chart Control, and I have 2 series. In my case 1 for month and 1 for year. The problem is when the chart control is displayed during run time for some reason the legend has 4 entries 1 says Mont, 1 says Year, 1 says Series 1, and 1 says series 2. My question is why are there 4 entries for the legend?

I am working with a chart control and on the Y axis i have numbers that fall between millions and billions.
The numbers on the axis themselves are not formatted and as such can be difficult to read. I wanted to know if there was a way for me to format the value that appears on the axis itself to be coma seperated?
here's what the Y axis looks like
600000000
300000000
100000000
numbers are just hard to read. How do i format them with coma's or even add a label saying (Millions) and then displaying only 100, 300, 600 etc
I can't figure out how to get the legend to populate all the "strReason" and get the correct percents to show for each column. This is where I'm at right now.

I have a DevExpress WebChart Control that binds to a DataTable. The chart control renders fine from the DataTable until I try to import data from a details view(i think the chart control renders before the detailsview?).
Here is three renderings.
Chart 1. just rendering from the datatable
Chart 2 The sqldatasource gets its para. from the values of two label controls to render the detailsview. The detailsview renders fine
Chart 3, the problem comes in when I try to extract the values from the DetailsView to populate the Chart, I loose the value. I am assuming the the datatable is built before the rendering of the detailsview? Lost at this point.
