Forms Data Controls :: Bind ArrayList To DataGrid And Reference Them?
Jul 23, 2010
I have an ArrayList of strings called 'vins'. I have set DataGrid1's data source set to 'vins'. 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'm trying to make it so that a user can click on a link after any VIN number and have that referenced and deleted from the arraylist. bind this ArrayList to the DataGrid and then be able to reference them.

I have a datagrid called studentAddList which is combined by 2 tables. Now I have a reportviewer called ReportViewer1. They are both placed on the same page. Now I would like to bind the datagrid studentAddList to the reportviewer ReportViewer1. The reason why I bind the datagrid to it is because I have some filtration on the data.

I have data in ParamList (from SQL reporting services database)which I want to display in a GridView. as ParameterName and VAlue. I am able to retrieve the parameters but can't figure out how to read them into ArrayList (or whatever method you coud suggest) and then bind to grid. Final grid should be like this-
ParameterName ParameterValue
Year 1011
Number1 0011
Number2 0101
Number3 0201
Here is the code I'm trying to figure out-
Dim intCount As Integer
Dim strparam As String
Dim strparam1 As String
Dim varResult As Object
Dim ParamList as string
ParamList = "Year=1011&Number1=0011&Number2=0101&Number3=0201"
varResult = Split(ParamList, "&")
Dim arrList As New ArrayList()
'loop through array and retrieve parms
For intCount = 0 To UBound(varResult)
varParam = Split(varResult(intCount), "=")
strparam1 = UCase(varParam(0))
strparam = varParam(1)
arrList = ???
Next
'and then display tsi data into a grid.
GridViewParams.DataSource = arrList

Simply put... I want to duplicate the example found at this link, in VB.net rather than C#.
[URL]
I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.

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:
[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 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

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?
