Web Forms :: Sort Datatable Does Not Work Properly?
Mar 15, 2010
now i use the dataview to sort the seq of datatable and bind to repeater, it can only display the seq correctly.but i found that it is not the actual database seq, when i remove the row from the datatable, it is not remove the record that i see from the UI.do i need to sort the seq to the actual datatable not the dataview.now i use the seq (int) in datatable to sort the datatable as belows:
DataView view = dt.DefaultView;
view.Sort = "SEQ";
repeater.datasource=view;
repeater.databind();

I'm looking for a way to sort the rows of a datatable without setting the DefaultView.Sort to a specific column. I have a datatable in session that users can add records to. I want them to be able to sort the data by clicking on a button. But new records added after that need to show up at the bottom of the list until the sort button is clicked again.

Tried several different ways to do this but am just not seeing it. Proably a quick solution for someone more skilled than me.
I have a gridview generated from a datatable. One of the columns is "client name" whose data is generated from a class.
I added a link button for the column header that fires a sub that should sort the datagrid, but is not.
Here is the code I have so far that creates the gridview which works fine:
Private Sub PopulateCaseListGrid()
'Kill the existing DataSource, in case of a page reload
gvCaseList.DataSource = Nothing
'Create a datatable with whatever column you want to use
[Code]....

Is it possible that once I have created a datatable programatically, I can then sort that datatable before binding it to a asp:repeater? I have a number of records that I have to get from a com object that has not been eliminated. The com object populates an array, then I loop through the array to pull data from my datatbase, adding the db data to the datatable. Then I bind the datatable to a repeater.
1) the array is multidimensional
2) The COM object doesn't sort the data by company ID (which is what I need to do)

I have a repository that contains all of my LINQ queries for this project that I am working on. I am able to get the LINQ results to a DataTable and bind that to a gridview for displaying the data. Now I need to make the gridview sortable. I have set AllowSorting="true" and I have the OnSort event handled in a routine in the codebehind.

I have got a datatable which contains many columns in which three are main:
hotelid
dshotelid
hotelname
Some hotels contain only dshotelid, some contains only hotelid and some contain both dshotelid and hotelid.
I need sort in such way so that those hotels who got both dshotelid and hotelid should be on top and then those hotels who have got only dshotelid and at last those hotels who have got only hotelid...
I created this :
dtmaintable.DefaultView.Sort = "dshotelid, hotelid"
but it Is not giving me desired output.

I wrote a statement such that
cmd ="select [title] from products where sku='% "3.5 caddy" %'"
this statement wont return anyfin where there is products with titles startin with 3.5 or ending with caddy or containing 3.5 caddy but just not together for example there is this title "3.5" IDE to USB 2.0 Aluminum External Silver HDD Enclosure Caddy" and that search of 3.5 caddy wont pick this item up as 3.5 is at the start and caddy is at the end.

I am trying to sort a DataTable. If I declare a DataView and use the following approach it works perfectly:
Dim dt As DataTable = getData()
Dim dv2 As New DataView(dt)
dv2.Sort = "surname, name"
dt = dv2.ToTable
I wanted to do this without using a DataView though if possible to reduce the impact on resources. I tried the following approach but it doesn't work. I might be writing the code wrong so
Dim dt As DataTable = getData()
dt.DefaultView.Sort = "surname, name"

I populate a DataTable, then sort the DefaultView of that DataTable. When I set the DataTable as the source for my report, the sort doesn't work. here is the code (GetData returns a valid DataTable):
Dim dt As DataTable = a.GetData(Parm1, Parm2, Parm3)
If rbtSortByField1.Checked Then
dt.DefaultView.Sort = "Field1 ASC"
ElseIf rbtSortByField2.Checked Then
dt.DefaultView.Sort = "Field2 ASC"
ElseIf rbtSortByField3.Checked Then
dt.DefaultView.Sort = "Field3 ASC"
End If
rpt.SetDataSource(dt.DefaultView.Table)
'This also doesn't work
'rpt.SetDataSource(dt)

I have a ListBox1 on the Form that I read in the same Directories: "GetS" as in the code below.
Now I select the first index wich is 0 in the listBox with the mouse and press Button1.
What the code below does is to find that specific folder that also contains a .BMP file and a file: File1.txt
So I will first delete the .bmp file and the File1.txt and at last the directory.
My problem is as follows. When I press Button1 the First time, nothing at all was deleted but the second time I press the Button1, the .BMP file and the File1.txt were delete fine.
But the code breaks at this line and says that the directory isnīt empty. But the directory is empty as I can see when open it manually.
So initially my problem is why the .BMP, File1.txt and the directory arenīt deleted at the first press of Button1 ? (ListBox1 has AutoPostBack set to TRUE and everything is put inside an updatepanel)

I thought that the "PageIndexChanged" is fired after the index has changed?
In other words when I'm at page 1 with a labelnumber 11 and I click on page 2, where the labelnumber =
22 and I do
the event "PageIndexChanged" I got the number "22" if I do the following code:
[Code]....
But that is not what happens I still got the labelnumber from page 1.
Did I understand the "PageIndexChanged" event wrong or is this a bug?
Because this is not working does somebody know how to solve this problem?

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. Example Filename: DailySalesReport-1-15-2010. My only hangup with this is how do I sort on date, when it's a string value? Convert to date? How would I sort the whole dataset based on this converted value?
