i am using asp.net chart control, problem i am facing is that it automatically generates values in Y-Axis.
As you can see in image , values 0, 3 and 4 are automatically generated. how to hide these automatic generated values.
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 can't find how to set font-style for titles on x and titles on y axes in the chart control? This titles are values, that are bind to chart control from database.
I tried this, but it only changes font-style for values on the top of each column.

i have a question, suppose i have a table 'tblImage' which have 3 rows of data and my auto increment is not +1.
imageId imageName
1 a.gif
2 b.gif
4 c.gif
i want to query '2' using LINQ C# to the table in MS SQL and show the record which i have done easily BUT now i want to get the next auto incremented value to make Next button on the sane web form, which is in this case is '4' and i also want the previous imageId as well.
I'm trying to get an IDENTITY column to auto-increment with each new row inserted, so that the field (userid in this case) can be used as a unique identifier.
However, I'm getting this error:

I don't understand - if I have to explicitly insert something into my auto-increment column, how do I know what to insert? Isn't the point of an auto-increment column that it's... auto?

View 1 RepliesI 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've created a stacked bar chart - so there are multiple series in a line. The series display the value, but when the value is 0 I don't want the value to be displayed because if there are multiple 0 value is starts to look like 0|0|0|0 i.e. not very nice on the eyes. I'm wondering if there is a way i can say if the value of the series is 0 dont display the value.

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 am using LINQ to store and retrieve data from tables with a clustered index key. However, I also need to know how to obtain an inserted table row identity with an auto-increment Primary key.

public partial class DataClassesDataContext : System.Data.Linq.DataContext

View 12 RepliesI got a table PartsMedia where I can insert all the images related to a product. The table has the columns :
PartsMediaID , auto-increment
PartsNo
MediaLink
MediaDescription
CatalogCode
SortCode
I want to insert a complete row with automatic increment and the PartsNo should be the same as the PartsNo from the PartsMaster table.
The medialink should be the PartsNo + '-2.jpg'
The mediadescription is for example 'image2'
The CatalogCode should be 'catalog'
and the sorting code should be '0'
From The partsMaster table I Just need the PartNo So I can add this to the PartMedia Table. The PartNo is the foreign key in the PartMedia table.
The following I got so far but no luck
insert into dbo.PartsMedia (PartNo,MediaLink,MediaDescription,CatalogCode, SortCode)
values (dbo.PartsMaster.PartNo, PartsMaster.PartNo+'-2.jpg','image2', 'catalog','0')
I use SQL Server and when I create a new table I make a specific field an auto increment
primary key. The problem is some people told me making the field an auto increment for the primary key means when deleting any record (they don't care about the auto increment field number) the field increases so at some point - if the type of my field is integer for example - the range of integer will be consumed totally and i will be in trouble.
So they tell me not to use this feature any more.The best solution is making this through the code by getting the max of my primary key then if the value does not exist the max will be 1 other wise max + 1.Any suggestions about this problem? Can I use the auto increment feature?I want also to know the cases which are not preferable to use auto increment ..and the alternatives...note :: this question is general not specific to any DBMS , i wanna to know is this true also for DBMSs like
