I'm sure this has been asked here before but i couldn't find it, anyway my issue is i have filled a dgv using a LINQ query and i need to sort my results by 2 columns, i.e. type and cost so that it lists items by each type in creasing cost[code]...
View 10 RepliesI currently have a datagridview that is built from a datatable So lets say we have 6 columns
A B C D E G
So the users will select there data from another program and paste into the the table. So lets assume that the data that is pasted is; (the column names are automatically put in)
A B C D E G
123 456 789 101 112 134
So the table will now look like following (I remove the first row because its the same as the column name)
A B C D E G
A B C D E G
123 456 789 101 112 134
My problem is that the users can rearrange thier tables(column index) so lets say user A has the table in this format
A B D E C G
123 456 101 112 789 134
So when they paste into the program, it will look like
A B C D E G
A B D E C G
123 456 101 112 789 134
So now "C" "D" "E" are incorrect and i need to swap those columns to be the same as the column name. I'm not sure how to attack this problem.My thoughts were to paste the data as is, than see what the first row in each column equals.so if it equals "A" assign it an index 0
B 1
C 2
This seems theres too many steps and will slow down the app...
how would you sort out two columns so when you click them, it either sorts the listed items in Ascending/Descending order. I have named Name column to colName and Mobile column to colMobile

How can I set up my WPF datagrid to sort on multiple columns similar to having two sortable columns, clicking on the header of the first column for a primary sort and then SHIFT clicking on the header of the second column for a secondary sort. I would like the multiple column sort to happen automatically when the user clicks on the header of the first column without having to SHIFT click on the second column header. Is there a way to do this entirely in the xaml? If not how can I do this in the code behind? Currently using VB.Net but a C# snippet is acceptable if you have one.

I'm writing an application where as many of other applications fulfill the requirements to be as an app , having it's statistics schema. Thus I made a form where I have a combox(of query category), a textbox(as searchfield), two datetimepickers(from and to) a listview and a button to fire the event with functions in it. I'm all set except for a minor issue I've encountered during my very first experiments with ListView control. Thus far I didn't know that VB users are stuck with that control's property options (whereas DataGridView has way too many), especially when it came to Column reordering/s. With the simple but not satisfying property Sort I couldn't find a proper solution to my issue.
when I click on of the columns in the listview to do a Number/Date/Text reordering (descending>ascending, via-verse). Not to forget to mention there a limited number of columns most likely 2-4 max.
The listview control has lvResults name and has for now columns inserted as "Country" and the other for subitems "Total Spent".
One e.g. of the values inserted to it is like this :
[Code].....
If pressed on Total Spent, should reorder from highest to the lowest number and via-versa. If pressed on Country should reorder from A to Z or via-versa.
I'm trying to set something up where the user can sort each column by clicking on the header... i've looked at some other examples and they seem pretty longwinded..so far i have the below...
VB
Private Sub resultsListView_ColumnClick(ByVal sender As Object, ByVal e As System.Windows.Forms.ColumnClickEventArgs) Handles resultsListView.ColumnClick
Dim oldsort As SortOrder
[code]....
which works fine... but only for the first column in the list view.Is there a way of specifying which column to sort based on which is clicked?
I am trying to program my page in vb.net and asp.net so that when a user clicks on a column heading of a gridview, the data is sorted either in ascending or descending order. note that my data is coming from an SQL Server Express database. So far, I have done it so that the gridview can be sorted:

I fought through a good amount of this and have gotten to the point where I can sort my arrays. What I need to do now is take the following code and sort the elements in descending order instead of ascending order. I don't know how to do that with the two arguments in the code:
Dim Cols(3) As Int16
Cols(0) = ColumnNumber + 1
Cols(1) = ColumnNumber + 2
Cols(2) = ColumnNumber + 3
[Code].....
how do you sort the data by columns in a list view, for example, clicking the title of the column to sort by ascending order.

Select Case e.SortExpression
Case "Name"

What I would LIKE to do, is something more ... like this
Private Function SortThatList(ByVal listOfStuff As List(Of Stuff), ByVal isDescending As Boolean, ByVal expression As Func(Of Stuff)) As List(Of Stuff)
If (isDescending) Then

But it doesn't like the datatype (Of TKey) ... I've tired Func(Of stuff, boolean) (got something in c# that works nicely like that) but can't seem to get this one to do what I want.What's the magic syntax?

I have a few classes, one is a form, the other is the source of the datagridview. I want to be able to sort the columns of the datagridview by clicking on the header. Here are the classes that I am dealing with:

I have a DataGridView.DataSource set to a Collection of custom objects. The columns use read only properties from the custom object for display, this dialog is for display only. The properties all return String objects. I set the columns all but 2 of them to sortmode automatic (the ones that are not set is a button or a checkbox). Yet it does not sort. I have googled around and most people use sql or binding sources but I am using a trivial vb collection. Some say I should implement IComparable but isn't String already IComparable?
Per a request here are some code snippets.
This method defines the columns in detail from columns I designed in the designer.
The column names are called pSelected or pCustomer and corresponds with a property by the same name that the column definition ties to.

I am using VB.NET 2008 My DataGridView is bound to a DataSet. After adding a DataGridView row (from another form), I needed to sort the DataGridView in order to put the new row in the appropriate place. I needed to be able to identify the current sort column and the current sort direction (ascending/descending) but I was unable to find out how to obtain that information from the DataGridView properties. Consequently I had to do it the hard way via my own coding. The sort column name (or names) and the sort direction then became available to my program in the global variables.

I have the below bit of code that allows a user to see data in a DataGridView. They can click on a single row and open another form with the detail of the selected item. Once the user returns from that form I refresh the original screen with anything that might have been changed from the other screen (or by other users elsewhere in the network).
This works perfectly fine to select items, go look a the detail and change anything you like, then return and refresh the screen with the new updated information, with one notable exception. I get a NullExceptionError whenever the user has changed the default datagridview sort option on the first screens grid screen. Then selects and item and goes to the second screen and comes back to the first screen. And the really strange thing (to me) is that the first record on the return gets added fine, it is the second record it tries to add that is throwing the error.
Other notes: all variables have values (not nulls), the tableSelect is also valid and not equal to nothing.

Is it possible to disable the "sort function" in datagridview that happens when pressing the header?
I would like display some data that you cant order by clicking on the columheader. Can you lock the headers somehow?
Basically, I need to be able to click a row header to sort a datagridview, similar to how clicking a column performs a sort.
