I have AutoFilter in place in my sheet. I want to sort data using the AutoFilter itself and not by normal sort. I want the client to see the down arrow on the autofilter button, which tells that rows are sorted on this key.
I have 'sheet' as an object :
sheet.Range("A2").AutoFilter then Or something else ??(Ensure the syntax for VB.Net and not VB Script)

I am making some kind of calendar where I can add tasks, so I can easily organise my tasks. For it to complete, I have 3 things I can't figure out how to do it:
1. When I launch the program, I want the items in my listbox to be sorted alphabeticly.
2. I want to save the items in the listbox, so if I close the program and reopen it the items are still saved in the listbox.
3. The items in the listbox all start with a date, fe. "13-4" for today. If that date already passed I want that item to be deleted.
I have a form that has a DataGridView named dgvResults on it. When the form is initialized I bind dgvResults to a DataTable named prpResultsTable using a BindingSource named bs. Code shown below:
Public Class frmImportData
Private cv_clsB As clsBatch
Public Sub New(ByRef clsB As clsBatch)[code]....
The gist of the program is to:
- Read a CSV file into an array
- Get this visible in a list box, so the values can be:
- Sorted
- Edited
- Deleted
- Added
- Finally save these manipulated values back to the text file
Would love some suggestions and code as to how to get this going, hopefully I'll get the hang of it and come back and fourth for help
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.
My problem is once I filter my datagridview I cant seem to be able to update the database. The error I get is Concurrency violation: the Update Command affected 0 of the expected 1 records. Why is it that I cant update after i filter????

I'm having problems with bindingsource. I have a proc used to update a datagridview from a bindingsource. When I run the debugger, the datatable appears to be populated rowcount is 2206 and 7 columns. When the bindingsource.datasource is set, everything looks good. The filter appears to be ok, however, when the datagridview is set to the bindingsource, it's not working. I have it in a try/catch block and an error isn't being raised. When I reference the columns to size them, an error is raised. Below is the snippet of
