i am using mschart in vs2008 in that i want set our own color for each datapoint using c#. This for the pie chart etc.. and also if there is no data for data point i want point out that field in unique color.
View 3 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.
I am using the .net 3.5 chart controls and I am binding a chart to a datatable datasource. How do you keep the charts displayed after a postback has ocured. I bind my chart control. The on the page i make a change to a dropdownlist that issues a postback to the server. When the page reloads the charts have no data. How can you make the chart object persist it's data during postback?
View 1 RepliesDoes anyone have an example of using MSChart with a stored procedure? I have a chart control on the web page and have bound it to the stored procedure. I have also set the parameters for the stored procedure. However nothing shows in the chart. All the examples I can find only show adding points one at a time, but this seems to defeat the purpose of binding the chart to the stored procedure.
Some of the problems I am trying to solve:
The stored procedure returns about 6 columns of data. I only need to use two of them. How do I select which of the columns will be displayed in the chart?
I want to use two or more series on the chart. Do I have to run a separate stored procedure for each series or can I make one call to the stored procedure and then display the data in the two series? If so, how?

View 1 RepliesI have several gridviews on an aspx and each has a hyperlinkfield. All of them redirect to another page with a single gridview. I am trying to figure out how to get each hyperlinkfield to redirect to the actual point on the receiving page with the corresponding value. In the sample data below, I need to be able to click on 'def' and open aspx page 2 to the point on the page where 'def' is located. All values still need to be visible. Can anchors be used in gridviews?

This seems like it should be extremely simple. I have a list of x,y cords in SQL table that I am pulling out into a reader. I am then trying to bind my points to a point (have to use it since I can't find scatter) chart control.
Chart1.Series("Series1").Points.Databind(myReader, "Xpos", "Ypos", "Tooltip=CName")
Where Xpos = the x cord column and Ypos = the y cord column.The chart generates but my problem is that I am getting multiple x values that are the same. For example I have (67, 45) and (67,54).I would think there would be one x value for 67 with the two points on it, at 45 and at 54.Instead I am getting 2 x values listed, both for 67, one with 45 and one with 54.
Just as a test I listed these values in excel (in 2 columns) and did a scatter plot and it generated what I expected (2 items plotted on the same x value, one above the other. Is there a setting I am missing or does the chart control "Point" not have this capability.
I'm using SqlDataSource and at the point of adding a record, I've called SqlDataSource_UploadNewsLetter_Inserting. In here, I'm testing a value, and if it's true, I need to stop the insert from taking place. But how can I stop the database insert at this point?

I am developing a scheduling system in which customers are alloted 15 minute timeslots (see example below). During rowdatabound event I know how to change the value of Cell(1) to NULL by using e.Row.Cells(1).Text = "" so Select option is not available for that timeslot. This works fine for someone who has taken only 1 timeslot.
Question is, when a Customer has for example 1:00 hour appointment (which is 4 x 15 minute time slots), how do I make the next 3 rows Cell(1) value NULL?
Is there anything like e.Row+1.Cells(1).Text = "" or some loop that I can run to take care of next few rows?
