Asp.net - How To Correctly Filter A Datatable (datatable.select)
Jun 17, 2010
Dim dt As New DataTable Dim da As New SqlDataAdapter(s, c)
c.Open()
if Not IsNothing(da) Then
da.Fill(dt)
[code]...
When I call da.fill I am inserting all records from my query. I was then hoping to filter them to display only those where the GroupingID is equal to 0. When I run the above code. I am presented with all the data, the filter did not work. Please can you tell me how to get this working correctly.

have created a data table as global data table for the session. So when the user selects the drop down Address Type Main , Street, Emergency - I want the Address text fields to display based on user selects. So, for my dropdown i have datavaluefield column as addressid. And the datasource for this is datatable. I was having problems converting from datatable to dataview. Does anyone know how to do this? I was geting errors cant convert from datatable to dataview. I was choosing dataview because you have the filter option. But then I saw you could also select in data table. So I am trying to select a row in datatable with select with expression like this:
Dim dtAddress As
New DataTable
dtAddress = GlobalVariables.AddressTable

I have a ListView with Checkbox. My requirement is - When I click on any checkbox then it should return all the columns values of that row on behalf of that CheckBox. After much study I came to know that using DataTable and DataRow I can get all data of particular ID of a Row. But I am unable to work with this. My code is something like below:
DataTable dt=new DataTable();
dt=objBAL.Get_ShoppingCartData();
ListView1.DataSource=dt.Tables[0];
[Code].....

'DataTable' is an ambiguous reference between 'System.Data.DataTable' and 'Microsoft.Office.Interop.Word.DataTable'

I use the above code to return records from database. The above snippet would run in web application which expected to have around 5000 visitors daily. The records returned reach 20,000 or
over. The returned records are viewed (read-only) in paged GridView.
Would it be better to use DataReader instead of DataTable?
NOTE: two columns in the GridView are hyperlinked.

Many times I need to manipulate with DataTable after I get data from database using adapter.Fill(table).
Usually I calculate data in DataTable by using loops. But I know that there is simpler way using LINQ. I know some basics about that just for strongly typed objects.I can't find how to do this with DataTable that is not strongly typed. How could I get all DataRow or Filtered DataTable (not just value for the field) from table for that conditions:
- where the specified field of the table contans MAX/MIN/AVG value,
- where the specified field of the table equals to some value.

I create a DataTable and filter it. When I use filter1, everything works as expected. When I use filter2, everything works as expected only if the SubsectionAmount variable is less than 10. s soon as I set SubsectionAmount=10, the dr2 array returns Nothing.
Imports System.Data
Partial Class FilterTest
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Loa

Prior to adding paging using PagedDataSource I had dropdownlist and search box filters for my DataList. The guts of the code in aspx page for those parameters is below:
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
[code]....
When creating the pager using PagedDataSource I did a tutorial which did not have parameters and all the code went in the code behind page. The guts of it is below:
private void BindGrid()
{
string sql = "SELECT [ProductCode], [ImgUrl], [Featuring], [Title] FROM [TableSG1] DESC";
[code]....
The pager is great but now I need to add my filters. The page wont load if I add the "SelectParameters" code (above) to my aspx page and if I simply add the "WHERE" clause to the "SELECT" clause in the code behind I get an error stating that I need to add a scalar variable.
I have found some examples through googling but nothing specific enough.

I've built a User Control that contains a ListView. To make it work I need to pass to it a DataTable. The columns of this DataTable need to have particular names that match up with what the ListView is expecting. I have a large DataTable that I need to massage/convert over to this different format. To do that I need to filter out columns and rename the column names. The actual data in the DataTable doesn't need to change. Is there a good way to do this without actually instantiating a new DataTable and copying the data from the large DataTable into it?

I have a dataset generated from xml from a web service.Data needs to be sorted by date order descending, I cannot get the web service changed so thought I'd try:
Code:
repeater1.DataSource = dsCombinedBlock.Tables(2).Select("Status < 3 and status <> 99", "DateReceived desc")
However the dates are treated as a string so the results look like
28/06/2011
27/06/2011
27/06/2011
02/06/2011
01/07/2011
How do I get the proper ordering applied.

I have a DataTable of available time slots. I have another DataTable of reserved time slots. I need to remove from the list of available slots the ones that have been reserved. The blocks are in 15 minute increments, but one of my problems is that the reservation can be longer than 15 minutes. I've had some luck removing one or two, but not all of the required columns.
Here's my code (it doesn't work right now).
