How can I change the chart type of the chart control in ASP.NET 4. I have a drop down list that contains name of all the chart types. This is the code I came up with :
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
Chart2.Series["Series1"].ChartType = (SeriesChartType) Enum.Parse(typeof(SeriesChartType),DropDownList1.SelectedValue);
}
I'm having problem with MS Chart chart type column. If there are only 9 bar in the chart like the following picture, then the axis-x label show up properly.
However, there are more than 9 bars bar the chart, the axis-x label wont show up properly, some of them just dissappear.
Here's my mark-up for the chart:
[code]....
I don't know it works with only 9 bars? Is there any way to make the chart work properly? Also, if possible, how to make each bar have different color.
I have a details view in asp.net which I am dynamically replacing some of the controls using code behind (e.g. converting some text boxes to dropdowns). My problem is that I am unsure how to bind these to the field from the database on postback. I.e. I am trying to find the code behind equivalent bind('currency');
I can populate the dropdown with the current value from the database but cannot find how to save a new value on updating the detailsview.
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.

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).
I have X and Y data columns coming from database.
I have to show scatter plot chart with Linear, Exponential, Log, power using asp.net chart control.
How to do that?
Do anyone knows how to change the x-axis and y-axis of graph using dropdownlist which is being binded to a datasource and group according to years/months?
View 2 Repliesim trying to create simple pie chart using the MS Chart controls.

I am a novice programmer using ms chart control for my dashboard, I have a problem displaying chart series.
Here is my sample query & result
Sample Query: "SELECT Brand, sales, Manufacturer From TABLE"
Sample Result:
[code]....
How can I display BrandA for XValueMember & Salesvalue(10000) for YValueMembers as Series1 having a column chart type.
And to display BrandY & BrandZ for XValueMember ; Salesvalue for YValueMembers as Series2 having a line chart type.
I want my chart to have 2 Y-axis; Series1 for primary Y-axis & series2 for secondary Y-axis.
My problem here is how can I display BrandA in Series1 and BrandY,BrandZ in Series2 where the values are in the same field?
Or is it possible to set more than one data source for the chart control?
I've been working on this for two days but I wasn't able to get the desired result.
I am having a requirement, where I need to have a pie-chart, i need text around pie-chart , the text should be a hyperlink. Ex: we have 3 three fields A,B,C. A's ratio is 30%, B's ratio is 40%, c's ratio is 30% So pie chart gets divided into 3 parts, outside the graph , we should get the label A(in A's area only), when we point on , tool tip should say "A's ratio is 30 %'. I am working in .Net 3.5, VS 2008, using MS chart control(added explicitly by executing MSChart.exe.
View 1 RepliesIn my web forms application I have a site.master page with an update panel (Java Script ToolKit). Inside the update panel I have a survey and a columns chart to show its results. The chart properties are
visible = false
ImageStorageMode = UseImageLocation
RenderType = ImageTag
When the user votes, his/her vote is stored in a sql server table The chart is rebound to its data source
The chart visibility is set to true and the survey's questions are hidden. I've been trying to set the columns for the maximum and minimum values to a different color using the code I found in "Samples Environment for Microsoft Chart Controls" [URL] under Working with Chart Data Data Manipulation Finding Data Points Find Maximum and Minimum Values:
[Code]....
I have not got the columns to change their color. I have put the code inside every event handler I could think of (after it failed to work inside the page load event handler): Inside the chart Init, load, and pre_render handlers. Inside the click event handler for the voting button (before and after I call the chart.DataBind() method). Inside the page pre_render handler. Inside the ToolKitScriptManager pre_render handler. I checked the code behind the environment samples. All, to no avail.

How can I change the parameter value from Interger to String.
Here below is the part of the code that creates problem; the constant "sqlStatement" is as string, but when the parameters "@ProdColor" read the value it returns an integer instead of the proper type which is a string. I have tried every ting like: CType(sqlStatement(splitItems(1)), string)
Or convert or parse, but it keeps returning the wrong type.
Const sqlStatement As String = "INSERT INTO ProductDetails (ProdID,ProdColor,ProdSize) VALUES"
If item.Contains(",") Then
splitItems = item.Split(",".ToCharArray)
cmd.Parameters.AddWithValue("@ProdID", SqlDBType.Int).Value = sqlStatement(splitItems(0))
cmd.Parameters.AddWithValue("@ProdColor", SqlDBType.NVarchar).Value = sqlStatement(splitItems(1))
cmd.Parameters.AddWithValue("@ProdSize", SqlDBType.NVarchar).Value = sqlStatement(splitItems(2))
I have a custom implementation of Application_PreRequestHandlerExecute which is applying a deflate/gzip filter to the response. However, on IIS7, this is failing on my "script generator" pages. These aspx pages take in Query String values and return a custom bit of script, changing the response type to text/javascript. I think it is failing because of the way iis7 uses mime types, but I'm unsure how to fix it short of turning all compressio off.
View 1 RepliesI have static html paypal buynow button that works great, but it's static.
[Code]....
But it is possible to change the values for the hidden inputs from .net codebehind code? I found this post which takes a different approach of sending these hidden fields instead as a query string to paypal. Not sure I like that though as would this not possiby explose some of those fields like the return page?
http://www.makaistudio.com/mksBlog/post/ASPNet-and-Paypal-buy-now-button-Offer-discount-at-checkout-in-code-behind.aspx
Basically what id like to do change the important parts of the button and info I'm sending to make it dynamic.I know I can do something like this in the markup, but that would mean having to fetch data mulitple times was hoping I could somehow adderss the field values directly in the codebehind. Or possibly dynaically generate and insert the entire changing input type fields from the codebehind
<input type="hidden" name="invoice" value="<%= getinvoice()%>">
Possible to add them with something like this: myform.Attirbutes.Add (???). If so how do I contruct these input types in .net?As far as return logic security, I've tested that it's solid, i just need to automate the button process so I don't have to create a buy now page and button for each product.
