So far I have the following code: (which works)
sqlLookup = "SELECT * FROM locations";
string connectionString = WebConfigurationManager.ConnectionStrings["LocationDatabaseConnectionString"].ConnectionString;
SqlConnection myConnection = new SqlConnection(connectionString);
myConnection.Open();
SqlCommand myCommand = new SqlCommand(sqlLookup, myConnection);
SqlDataReader myReader = myCommand.ExecuteReader();
while (myReader.Read())
{
locationCode = myReader["locationCode"].ToString();
locationName = myReader["locationName"].ToString();
notes = myReader["notes"].ToString();
}
In the past I used to inject HTML into a DIV element via the WHILE loop but this always creates a huge delay when renering the page. Is there a better method?

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?

View 2 RepliesThis 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 need to display binary data (that is stored in the database) in the aspx page. The file types are word and pdf. Since there might be multiple files, what I did was created IFrames dynamically and tried to embed the binary data. The problem is rather than embeding the word doc or pdf doc in the page, it displays the open/save dialog box.
is there any way to solve this (embed the word/pdf doc in the page itself)?

I am using Visual Studio 2005 and want to show a graph on a webpage using CrystalReportViewer.I have successfully shown the graph. But in the CrystalReportViewer i find that the entire crystal report page including the graph is shown in the viewer.In my report the graph occupies just the header section. I have no use for the rest of the sections.So the CrystalReportViewer includes a lot of white spaces that has been left empty.My understanding is that when we create a report the report uses the page format(A4, A5, etc). Hence the large page with white spaces.
???>> Is there any workaround to this?
My graph is a small one i think page size(A7). I am currently looking for a printer driver to install in my PC which supports A7 paper. So i can change the paper size from the printer setup. So that the report does not occupy extra space than required.
I have datatable like
Name Sub
abc x
dfe y
abc z
I need the out put as
Name sub
abc x
abc z
and
Name Sub
dfe y

I'm creating dynamic controls based on a tree structure I built from a database.
Basically each part number in my tree, I want to be able to type in a serial number for, so the form will look something like this:
Part 1 [textbox] [save button]
Subpart of Part 1 [textbox] [save button]
Subpart of Part 1 [textbox] [save button]
Part 2 [textbox] [save button]
and so on. I have the generating of the controls correct right now. However, all of the controls just come out in one line like the following:
Part 1 [textbox] [save button] Subpart of Part 1 [textbox] [save button] Subpart of Part 1 [textbox] [save button] etc..
How do I go about putting a break in between each "row" I'm making so I can obtain the tree format I am looking for?
