View 1 RepliesI have an arraylist that contains some values. (e.g. playerName). I also queried for values in the database (e.g. playerName, playerSales) and I need to match the playerName in the arraylist to the corresponding ones that I did a query from the database. (match those with the same playerName). From there, I need to create a bar graph with the respective playerName and their sales (playerSales).
A portion of the code is shown below:
[Code]....
The arraylist I mentioned was saved to a session to be used in another page. Is my code right? And how can I create the graph from the values?
I have a gridview on a web page as shown below
[Code]....
On checking the checkbox, the user will actually be selecting the products that he/she wants. The selected products will be stored in an arraylist by using a foreach loop through the gridview. The arraylist will then be saved to a session before being redirected to another page. (a button will be clicked after the selection of products to proceeed to another page)
On the redirected page, a bar graph needs to be generated based on the products selected previously and also the product sales (this is retrieved from the database).
How can I generate this bar graph without having to code the whole graph out?
I have a web page where a GridView will be shown with a column of different products and another column with checkboxes. Checking on the checkboxes will be equivalent to selecting the products. The selected products are saved to an arraylist. Then, the user has to click on a button located on the same page to analyze the selected products. On clicking the button, he/she will be directed to another page where a bar graph will be shown. The bar graph will be the result of having analyzed the products. How do I create the bar graph where the products are taken from the arraylist but I can make use of the datasource within the chart control to retrieve more detailed info(such as product sales) from the database, taking into account the products from the arraylist?

Reason i dont want to use auto postback is - by using it the controls didnt get selected in very first time hence behaving unexpectedly.

View 10 RepliesI wondered how the more experienced .netters out there would go about creating something whereby users could create online surveys? I can't get my head around it at the moment as I have my survey object but need to store different object types of questions within it. Also does anyone think that creating some custom controls could be the way to go? (survey question controls)

Which chart component should i use for drawing graph and how do i make sure that the data will be refreshed very fast on the graph web page.
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 begginer and I would like an example how create a simple custom control that only needs DLL reference like this:
<%@ Register Assembly="myControl" Namespace="myControl" TagPrefix="cc1" %>
<cc1:myControl ID="myControl1" runat="server" name="" size=""..... />

View 1 RepliesI am trying to find duration of an mp4 file using direct show component of windows using the Dotnet wrapper(directShow-lib 2005). But the method i used was GetDuration of IMediaSeeking interface. But this returns zero as duration.After searching i found the following statement:"It doesn't matter whether it's in a container or not, it only matters whether you have a parser/reader for it. There is no stock DirectShow parser to read raw H.264 files and no third-party one I can think of. Also, whether IMediaSeeking would work with such a raw file is implementation-dependent. Last, most H.264-related filters use MPEG2Video or
VideoInfo2 and neither works with MediaDet, so you would have to build the graph yourself."
I am building a web application using sql server reporting services. As part of my application, I present the report onwards to the end user using the report viewer control.
The reports that I have created are mostly very squeezed. That means that I have several graphs on the same single report.
What I want to do, is give the user the ability to focus on a single report. I've created the appropriate client side code, though now I am faced with a rather tedious problem. The image that the report reviewer renders is relatively small (as I needed to fit several graphs on the same single report). when I try enlarging the graph's image on the client side, it gets stretched. The image is rendered small!
How can I instruct SSRS to create a bigger image of the graph? Can I specify anything in the underlying querystring?
