Vb.net - Capture Mouseover Of An Individual Bar / Datapoint In Chart Control?
Jan 5, 2011
I have a single series bar chart created programmatically in codebehind which I would like to display the Y point value (somewhere above the bar, or maybe as a tooltip) when the user hovers their mouse over a bar. Is there a native onmouseover event for the bars of the chart, or is it something that should be added through series.MapAreaAttributes?
Edit After some experimenting I've found the points.tooltip attribute which I can add at the same time I add the point which will do what I want it to do, but it would still be nice to know if you can capture events for the bars, just for future reference.

In 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.

Am I going mad/blind? Probably a combination of the two.
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
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 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).

im trying to create simple pie chart using the MS Chart controls. When my pie chart gets rendered in the browser i get padding around the pie chart that i cant get rid of. i would like the pie chart to sit up against the edge of the image with no padding or margin. in my code below the padding is highlighted in blue. i.e Chart1.BackColor = System.Drawing.Color.Blue;
<script type="text/C#" runat="server">
protected void Page_Load(object sender, EventArgs e)
{
//Set the chart type
Chart1.Series["Series1"].ChartType = SeriesChartType.Pie;
//add points
Chart1.Series["Series1"].Points.AddY(12);
Chart1.Series["Series1"].Points.AddY(45);
Chart1.Series["Series1"].Points.AddY(67);
//set back color of chart object
Chart1.BackColor = System.Drawing.Color.Blue;
//set back color of chart area
Chart1.ChartAreas["ChartArea1"].BackColor = System.Drawing.Color.Green;
}
</script>
<asp:Chart ID="Chart1" runat="server">
<Series>
<asp:Series Name="Series1" ChartType="Pie">
</asp:Series>
</Series>
<ChartAreas>
<asp:ChartArea Name="ChartArea1">

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 using the validation controls, and I would like to display nothing for each individual control, but a message box summary. However, my validators are within a Repeater (see below) and each row can have up to 2 errors, and I want some way to be able to show in my summary whether ANY row has Error 1 or ANY row has Error 2. I.e. I want my summary to say 'The Grid contains Error 1 (new line) The Grid contains Error 2'. At the moment my summary gives me a separate line for each row where there is an error. Here is my code:
[Code]....
<asp:ValidationSummary ID="valSum" runat="server" ShowMessageBox="True"
ShowSummary="false" DisplayMode="BulletList" HeaderText="The following errors have been made in the order numbers:" />

I also have a working application that popukates my datagrid with valid data rows from my DataBase. What I cant figure out is how to get each of the hyperlink lables to NAVIGATE to the correct and corresponding aspx page!
For example I have 5 rows in the datagrid and each row has its own hyperlink, each row contains contact and a short profile on 5 diffrent companies. For example when i click on let say row 3 that has (eg) Jimmy's Big Prawn's Restaurant listed in the the datagrid, I want to be navigated to a webform page dedicated to Jimmy's Big Prawn Restaurant.
[Code]....
I am guesing it has to do with the bolded text above, but "details.aspx" is just an empty webform, I would like the hyperlink to point to (eg) JimmBigPrawnRestaurant.aspx.
