VS 2010 : Datagrid Multiple Column Sort?
Jan 19, 2012
I have a table with two columns, date and time. I am using the following code to sort in descending date order.
VB
If historydataGrid.Rows.Count > 0 Then
'if there are rows, sort by date (most recent first)
historydataGrid.Sort(historydataGrid.Columns(0), System.ComponentModel.ListSortDirection.Descending)
End If
Where Columns(0) is the Date. However, how difficult is it for me to then sort secondarily by time. So that the grid will sort by most recent date and time.. Working down from the most recent time on the most recent date, and then moving backwards towards the oldest date with the oldest time.

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

I have use this code to view my database into my datagird
Dim dbPath As String = "Provider=Microsoft.Jet.Oledb.4.0; Data Source=../VG.mdb;Persist Security Info=False"
Dim dt As New DataTable
Dim ds As New DataSet
Dim da As New OleDbDataAdapter
da = New OleDbDataAdapter("Select * from Marriage", dbPath)
ds.Tables.Add(dt)
da.Fill(dt)
Now every time I visit that form I have to manually click the column header of "EventDate" to that it will sort Descending. Is there a way to automatically sort it every time I visit this form?

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 am using vb.net2010. (express)
I am currently writing a bit of software for myself and need guidance.
I have a datagridview on a form with a date column. (column0)
I am trying to sort this by date desending but it will only sort by the day (dd) and not the whole date (dd/mm/yyyy) which leaves the months and years unsorted.
(example of output):
#1 - 01/03/2012
#2 - 02/01/2010
#3 - 03/02/2011

I have been told " Make sure the Date column is a date type and not a string " which i have taken as the access database column type. I have set this as Date but it still won't sort the column in datagrid view by the whole date.

so i have this data grid, which i wanna search , base on specific criteria from two or more text boxes; eg a user wants to search employees from karachi, so they enter karachi in the first text box. now they want to search employees from karachi whose status is permanent, so they enter permanent in the second text box, and the data grid shows employees from karachi whose status is permanent.
For search from ONE text box, i have used the following code :
Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.KeyUp
If TextBox1.Enabled = True Then

I have a datagrid that I am unable to change the width setting, it always reverts back to the original setting.
To change this setting:
1. select the datagrid view tasks
2. Edit columns bound column properties
3. Select Width property
4. Width property will always revert back to the original setting.
I have check the properties settings without any luck.

I have a .Net 4.0 WPF application using a data grid. Currently after sorting by a column, the scroll position of the grid stays where it was before the sort.For this application, I need to scroll to the top of the grid after any sort.I've tried handling the sorting event like this
[code]...
But this appears to fire before the sorting takes place and doesn't perform the scroll.

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

Property GridViewSortDirection() As SortDirection

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

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?
