VS 2005 DGV Column Click - Sort And Re-position To Previously Selected Row?
Apr 26, 2012
Here's the issue in a nutshell (I can elaborate if you feel it's needed). In a DataGridView I want to capture the value of the row's key column so that when the user clicks on a column header to sort the data, I can reposition to the row that was selected prior to the click. The problem is that the sorting itself, once it's done, fires the same events (RowEnter for example) that I used to determine my key value, so it sets my variable to a new value and now

It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?
Private Sub DataGridView1_ColumnHeaderMouseClick(sender As Object, e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView1.ColumnHeaderMouseClick

Property GridViewSortDirection() As SortDirection
Get
If IsNothing(ViewState.Item("GridViewSortDirection")) Then
Return SortDirection.Descending

I created a DataGrid by dropping a DataSource on my Form. When I run it in debug, it works great.
My question is:
When I click on a column to sort by, ascending or descending, how can I tell which column was clicked on, and whether it is ascending or descending?

I am creating a datatable and then adding a column to it which is filled with data from existing column and parsed into correct format DateSold is my existing column from my datafile and I create NewDateSold by adding the column to the existing table and then parsing the information in date format.
This is added to a binding source which then is used to populate a combobox I want to be able to sort the combo box by NewDateSold Desc I was able to this on the original column by simply using the "order By" in my query, it seems now that I added new column it is no longer sorted? I am finding different solution such as using dataview and wish to know the best way to do this

I want to choose a value dynamically from comboBox depending of the values selected previously in two comboBoxes.the code that loads the comboBoxes:
Private Sub LightClassComboBox_DropDown(ByVal sender As Object, ByVal e As System.EventArgs) Handles AreaClasificationComboBox.DropDown
TrafficDensityComboBox.DropDown,.....
[code]....
The problem is that in the last Sub in the If sentence gives an error of: Null Reference Exception, because the compiler thinks that in that event the data are not loaded, although the data are loaded when loadcomboBoxes sub is executed.

The dropdown box displays all the items previously added to that column.
I want the user to be able to enter a new value OR just pick a previous value from the dropdown list. (This is when inserting a new row)
Problem:
Whenever I enter a value, it jumps around in my table like its on acid or something. Whenever I select a value from the list, it takes me to the line in which the value was originally entered.
How do I get it to do what I want.

I have a listview set up in Details View and I run a ascending/descending sort routine on the appropriate column when the user clicks one of the column headers.However, when I switch companies and reload the listview with new information, for some reason the event fires and I get an indexoutofrange exception as I believe that the information has not yet loaded when this fires.The e.Column property is set to that of the previous column which I clicked even though I have clicked nothing.

What I am trying to do is sort a datagridview and remove a row from its sorted position to the 1st row.
The problem I am experiencing is as follows:
in the source below, when the code runs "MeanRow" is populated with what is required. As soon as Rows.Remove() executes, the MeanRow datarow is lost. Why would this be if I'm declaring a new variable and simply setting it?
Code:
MeanRow = r
TabGrid(dgv.Name).Datatable.Rows.Remove(r)
Code:
Private Sub dgv_Sorted(ByVal sender As Object, ByVal e As EventArgs)
Dim MeanRow As DataRow

I am using structures in my programming and I sort the structure according to a value in the structure using IComparer.This is a simple example for what I want.
Dim MyArray(6) As Integer
MyArray(0) = 1
MyArray(1) = 45
[code]....
How does number 1 get sorted? Is it brings the newest 1 to top or keeps the old 1in the same index? In my original example (before sorting), MyArray(0) = 1 and after sorting MyArray(0) = 1.Is this the same original 1 or this another 1 (the newest one added to the array) moved to that position?In case the MyArray(0) = 1 after sorting should be MyArray(5) = 1 before sorting.
Here is my a sample of my Code:
Public Structure ToSolve
Dim Con(,) As Integer
Dim Discharge(,) As Double
[code]....
Using all these methods, how can I preserve the positions of similar number in the list? i.e. I want to bring the newest 'Similar' value to the top of the list.

I then modify the items, add more items, etc..after I'm done modifying them, how could I send the items from the treeview back to theyre original position in the listbox?

I am reading an Excel file into VB.NET. There are 4 columns containing dollar figures of varying amounts. Here is what I need to do is identify the columns with the highest $ figure, the next highest, etc. and mark them so that .NET can identify them (e.g. col3 is highest so rank1 variable is "col3" and so on).So I am dealing with Excel Ojects which is new to me and sorting which is new to me. If it helps, here is how I am reading in the Excel file:
xlsWorkBook = xlsApp.Workbooks.Open(folders(f).ToString & "" & fileInFolder.ToString)
xlsWorkSheet = xlsWorkBook.Worksheets("Sheet1")
Dim ColumnNumber As Integer = xlsWorkSheet.Cells(1, StartColumn).Column

Is it possible, out of the box, to sort a .NET DataGridView column using only the keyboard?I understand there is a SelectionMode property, but changing this merely allows me to select, using Shift+Space, an entire row or column, but this doesn't have the same effect as clicking the header with the mouse and causing a sort.The reason I ask is because I am working on accessibility issues and would like to avoid relying on the mouse.

Dim array1(9,2) as String
So basically, 10 rows and 3 columns and say I want to sort them by the values in the 3rd column.
Each row is essentially a record of data and must be kept together.
Now I know that you can't use the array.sort method but would I have to use a bubble sort or something for this?
What's a good way to manipulate the records while still keeping each row linked together somehow.

I have a range in excel and I want to be able to sort it by one column programmatically.
There is range.sort, but it has a ridiculous about of parameters and I cannot get it to work.
Surely there must be something to be able say I want this data to be sorted by this column?
