Sorting With DataView - Dataview Always Sort The Highest Number Is The Buttom
Jan 5, 2012
I got a problem with dataview that get data from datatabel (Col1 : ID,Col2: Time) and I'm sorting by Time in desc ... when the values for example {40.21,80.21,70.25,25.2} the dataview sorting them as I need but when one of values goes above 100 for example {40.21,80.21,100.25,25.2} the dataview always sort the highest number is the buttom, I don't know why ..
This is a sample code
Dim dt As New DataTable
dt.Columns.Add("ID")
dt.Columns.Add("Time")
[CODE]...

If want to do a DataView.Find on a DataTable that is already 'ORDERED' by the Column I am seaching, so a DataView.SORT should not be necessary, but it throws an Exception if I don't give a .sort command before the .find command. Is there any way to avoid this apparant duplication ? and speed up the search time. Its a very large table - 1 million rows. I am using VB 2010

I have a dataview object that is being populated by database fields - so I can sort on these partulular columns by specifying the actual column names without any difficulty. However, I have been asked to add a few more columns to the dataview, and these columns will be calculated columns, not directly derived from an underlying database column.The users want to be able to sort on these new columns as well - even though there is no actual column name I can use to sort.
I have not been able to see where I can sort a dataview based on the actual column integer value used when the user clicks the appropriate heading to sort.

I'm trying to pull a table from an SQL database and sort it on the "Date From" (DtFr) column, which represents the start of a lease. I thought it would be as easy as this:[code]......You were right about the string value. I added a data column called sortDtFr to the datatable and gave it System.DateTime as a datatype and iterated through the rows setting the new column's value equal to the old one casted as a Date. Here's the code for those interested:listing all drives with GetLogicalDrives()..I am getting ( A:. C:, K: )

I have an XML that looks like this:
CODE:
This allows me to sort by the primary Author, Series, Episode, and Title.
In my application I house the data in a DataSet and then use a DataView to reference it in a Grid.
I'm using VS2005, VB.NET, and I have two questions:
1) How do I replicate the Sort I'm using in my XSLT?
2) How do I pull the primary Author up to the Book level so that it can be displayed in the Grid?

I have a page which lists all the files in a particular folder (all PDFs), using a data-table and gridview. I'm currently sorting this table by the filename (by using a dataview), which isn't that helpful, and I want the gridview of files sorted by the file created or file modified date (as recorded in Windows). If that's not possible, a second option would be to extract the date from the file name string (no problem doing that), and sort the dataview/datatable or gridview based on that.

I am trying to do a search on a index/row number taken from a dataview i.e. I enter 379437 in the input box which I know has a index/row number of 6. Now when I replace the Rows(index) with a Rows(6) I get the results that I want. When I run the code below the index comes out as 75 which displays the first row from the dataset which is a completely different set of results.

I'd like to know how to sort an array that has entries with numbers after text.
I have a list of four entries:
Book 1
Book 2
Book 11
Book 12
Using Array.Sort(aBooks) returns
Book 1
Book 11
Book 12
Book 2
Is there a way to have it sort lowest to highest like 1 2 11 12 instead of 1 11 12 2?

i am trying to add several rows to a dataview before bindng it to the datagridview. I have tried several variations of the below code but only the last row will actuall load into the grid. Probably doing something stupid.
My code is:
dvInspectDetail.AllowNew = True
Dim newRow1 As DataRowView = dvInspectDetail.AddNew
newRow1("IDetail") = mDetailNo.ToString

Looping through rows in a DataView
I have created a dataview from a datatable.
My question is how can I loop inside the dataview?
I know that in a datatable I can perform a loop like this:
For Each oRow as DataRow in iDataset.Tables("tableName")
Msgbox oRow(0).ToString
Next
How do i do that for a DataView?

I have a sqlDataSource that runs a stored procedure that returns a table of the days of the month that was passed in as a parameter, arranged as they would in a calendar. It also returns a second table which contains the event details associated with certain days of the month.Basically, how would I go about accessing the values contained in the 2nd table that is returned by my query?I have tried putting the result of the .select in a dataset, unfortunately I get a cast error. If I try to put it in a dataview, I only get the first table.[code]

I have a form where I open an Access database with 3 tables. I have defined datasets and dataviews for these three tables in the main form. I want to open a new form and access and update the tables using the dataviews I've already defined. When I try to access a record from the dataview using the new form, it's not defined. Can I pass the data between forms or do I need to redefine it in the new form? This is the first time I've tried to use multiple forms.

I am trying to create a basic webpage that will check a column of a database table to see if a "UPC Code" is taken already, to prevent duplicate use. I'm fairly new at .NET programming, but have built asp pages before. I'm just stumped :/
I have a textbox that a user can type in a number. The page successfully checks to see if the textbox is blank and reports the error, and if there is a value, it's supposed to bind that textbox number to a gridview to see which Item# it's associated with. But for some reason, my code is not binding the value of the textbox to the gridview.
Code:
<%@ Page Title="Home Page" Language="vb" MasterPageFile="~/Site.Master" AutoEventWireup="false"
CodeBehind="Default.aspx.vb" Inherits="UPC_Checker._Default" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
</asp:Content>

I have a form which is primarily pulled from Table1. Table1.fieldA is an integer representing a project phase. In the current Access display the form displays not the integer, but a String stored in Table2 that holds integer/String pairs representing all the phases.I'm trying to figure out the best way to reproduce this in my .NET formview. I could write code that would parse the int and display text, then reverse the process at save or insert, however then the code has to be updated if a new phase is added to the database. draw the String values from Table2 while preserving the binding to Table1 but I haven't figured out how.
