I have a single table that has (3) Fields displayed in their own combo boxes. Right now they can only be sorted by one set of criteria. Unfortunately that leaves the other (2) Combo Boxes in random order. When "One" of the values, in "One" of the combo boxes is updated, ALL 3 of them jump to the same record and display the correct data. This part works as designed.The problem is, I need to have a way to sort the other (2) Combo box's data, which is also populated from the same table, AT THE SAME TIME, so that all (3) present sorted data in each of the (3) Combo Boxes. Then when one of the combo boxes is updated, ALL (3) will get updated, just like they do now.THis data populates three of the cells in a data grid, and then the underlyting table(s) after saving. Like I said, the (3) work, but only with one of the orders sorted. I need the same exact functionality, but with (3) different sort orders on the (3) Boxes.The (3) Combo Boxes are:
1.) cb_PlayerNumber - A Sorted list by the Player's Number (2 Digits as String)
2.) cb_Lastname - A Sorted List By player's Last Name (String)
3.) cb_FirstName - A Sorted List by the Player's First Name (String)
The table these three combo boxes is populated from is the "Players" Table. they all populate perspective colums in the "Gamedata" Datagrid, along with selected data from combo boxes populated from other tables which, when saved updates the "GameData" Table.

I have a datagridview showing data from an Access database. I have dragged the datagridview from "Data Sources" window - and not written any code. In bindingsource I have choose to sort on an autonumber field. Is it possible to let the user use the mouse to change the order, and the database to remember this the next time the user starts the application.I guess I have to have a number field in the database, and write code to change the value in number field as the user change order - and then save this back to the database? Does the datagridview support changing order by mouse at all?

I am trying to use bubble sort to sort to sort the deatils shown on the datagrid. The buuble sort code is there and the data grid view code is there which retrives the product details in my databse. How would i link the two together so that when the user clicks the button it uses the bubble sort code to sort and view the product deatils in order of the selected coulmn name selected by the user through a combo box?
i wanted to link options selected from Comb box A (general) to specific options in combo box B (specific). I want to pick a word in Combo box A that has specific words/phrases in Combo Box B show. But not all the words to show in the combo box B if they aren't associated with the Word picked in Combo Box A. Ex.When "Soda" is picked in A, only "Coke, Sprite, Fanta" should be visible in combo box b, not everything else.This is the code i used to make the boxes, but i don't know how to link them.
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' fills the combo boxes with values
Me.xGeneralComboBox.Items.Add("Soda")
Me.xGeneralComboBox.Items.Add("Juice")

How to use a databound combo box to display one field in the drop down, and another as the combo box text on roll up? Using VS 2005... For example, I have a datatable that has 2 fields. One called "ShortDesc" and one called "LongDesc". I want to be able to see the "LongDesc" column values in the drop down on the combo box. When I make a selection, I want the text in the combo box to read the corresponding "ShortDesc" value.

I am getting an error when i try to populate some combo boxes with a value, the combo box has values in and the right amount the code is getting the right number.

Combo box 2 is filled based on a selection made in combo box 1 and a listview is populated based on the selection made in combo box 2.When the LostFocus event completes in combo box 1, it hits the LostFocus event in Combo Box 2 but it shouldn't. How do I prevent this from happening or if I can't prevent it, how do I work around it? The following is the code used.
Private Sub cboCategory_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles cboCategory.LostFocus

I�m using VB.Net 2008 application program.I�m using DataGridView, where column types DataGridViewTextBoxColumn. I have 3 fields. 1 field values are numeric, 1 field values are string and 1 field values are decimal.
When I try to sort the string value column, it sorts correctly. But when i try to sort the numeric value column, it sorts as if its string value.

I have a 2D array which holds 5 students and two test results. I have initialised my array as studentTestResults(4,1) However, I am looking for a sorting algorithm which will displays the students in order of combined results when the user clicks "sort results". I have had a hard look around the net, but finding a bubble sort for a 2D array is difficult, especially as my knowledge is minimal.
[Code]...
I've learned about and understand HOW to do a bubble sort (theoretically), but I can't seem to wrap my head around how to use a bubble sort with array structures. I'm supposed to be able to sort the inputted student information (via textfile) using bubble sort and display the result in a listbox. Buttons for Sort by last name, sort by gpa, & sort by letter grade.

I have a VB 2008 connected to my localhost SQL using DataGridview, BindingSource and DataTable. All works fine, i can add, edit and delete the row and the SQL database is also affected.
However, there is one thing that bugs me, that is sorting.
Problem My table in this database is still quite empty, it only has 6 rows
However, if I spam-click the column header, the sorting seems taking some time to sort, so that, the sorting result does not follow my mouse spam-clickings
Note: Spam Click = Clicking the mouse button in high frequency, something like click click click click click click click click click, etc
I then make a debug button to check this
Variables:
Dim DebugInt As Integer = 0
Dim bs As New BindingSource

After a long time searching, I am still facing an issue with my listview column header I am trying to add a sort indicator (a small 16x16 arrow, next to the column title - looks quite good).
- My listview is in Ownerdraw mode for : Items & Subitems for a couple of reasons
- So far, I was letting the system do the job for the header (e.drawdefault = true)
I managed to add very easily the arrow using the e.graphics class, right after the e.drawdefault=true, and it is actually working good.
print01.gif
(Sub ColumnHeader OwnerDraw)
e.DrawDefault = True
e.Graphics.DrawImage(My.Resources.fleche_v2_16x16, 34, 2, 16, 16)
As you can see, I'm simply using a resource, and am forcing it to 16x16 with a custom location x=34 pixels y=2pixels My issue comes with the following :
(Sub ColumnHeader OwnerDraw)
e.DrawDefault = True
e.Graphics.DrawImage(My.Resources.fleche_v2_16x16, (e.Bounds.X + 34), 2, 16, 16)
The arrow wont draw Of course the sort indicator will sometime be on the 2nd column etc.. That's why I need to use the column header's bounds.I can already hear you saying : if you do not owner draw, you can't..But why is it working with a static location (, 34, 2, 16, 16) ans not starting from another static location (e.bounds.x) How can I fix that ? I cant find previous issues similar to that one over the internet.
Points of interest :
- I tryed to load the int value e.bounds.x into a variable before, using that instead of e.bounds.x but it's all the same.
- Using the imagelist is not an option, As you can tell from the screenshot, I am already using images for headers.. the sort indicator is coming as another image
- Using ">" or "<" in the header's text is not an option either........ (sorry pal It does not look good at all..)
- Drawing the header totally in owner draw mode would be an option, but it looks quite hard to do (need to manage the "rounded" header style of the system, the mouse over - small yellow line rounded on the sides in WinXp, the click effect....).
