View 3 RepliesI'm trying to create a public arraylist that references a single field inside an sql table.

I need to create a public bool that checks a string for items in an arraylist.

I'm not experienced enough with the foreach statement to quite figure out what I'm doing wrong here.
I have a GridView control of 5 columns out of which 2 are actually computed (there cell values comes from column 1, 2 and 3) columns. I want to save all the values of my gridview columns in a 5 dimension ArrayList and then lateron bind that ArrayList with a repeator control.

At the point where rows are added to dt, i'm trying to get arraylist (Tweet) to be read row by row to insert each of it's fields into dt. There is no error but when run in browser, each cell of the gridview shows 'DataExtraction.Tweet'.I'm not sure where to go from here.
I 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:

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 that contains template fields with textboxes that is used to look up inventory items. The page loads using an arraylist to display a gridview control with a predetermined number of rows. There is also drop down control that allows the user to add additional rows to the gridview if needed.
Currently when a user has already entered some data if you use the drop down to add more empty rows all the original entrys are removed. I want to save the original data and then add empty rows at the end.

Private Sub LoadDataGrid(ByVal numberOfRows As Integer)
Dim Counter As Integer
Dim GridList As New ArrayList
For Counter = 0 To numberOfRows
GridList.Add(New LibVB.Form2VB(Counter))
Next
gvEnterParts.DataSource = GridList
gvEnterParts.DataBind()
End Sub

When I check off create columns automatically at runtime the DataGrid is populated with the correct values from the arraylist, however I'm not sure how to reference them.

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 3 RepliesI have looked through the website and google about crystal reports and MVC. It seems that crystal reports does not goes well with MVC framework. Is that true? If that's the case, what is the best solution for me? I am assigned to generate graphs and reports by getting data directly from a database (Oracle) and populate them into a report document. Other than crystal report, what can i use.
Is crystal report capable of generating graphs? or do I need to download other add-ons in order to have a graph generation on my reports.
I'm new to asp.net and I'm trying to implement a shopping cart.With the following code (. Vb):
PartialClass a Inherits System.Web.UI.Page Protected Sub Page_Load(sender As Object, eAs System.EventArgs) Handles Me.Load Dim FileNames As ArrayList =Session("SessionCarrito") If FileNames IsNot Nothing Then For Each Fname As String InFileNames ListBox1.Items.Add(Fname) Next End If End Sub End Class
