Getting WPF DataGrid Selection Direction?
Jan 20, 2011I'm using SelectionMode as Extended (multi select) with WPF DataGrid.The SelectedIndex value always returns the first row that was selected, irrespective of the selection direction. For example, if I start at index 0 and end at 4, I can work with it fine. But if I start from 4 and go to 0, SelectedIndex returns 4 and I don't have a clue to add the number of selected cells or subtract.Is there a way to find the selection direction?

Aug 24, 2011I 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

View 2 RepliesC# - Sort On Multiple Columns In WPF Datagrid?
Jun 24, 2011How 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.

VS 2010 : Datagrid Multiple Column Sort?
Jan 19, 2012I 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.
VS 2010 Datagrid View Sort By Date?
Feb 7, 2012I 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
[Code]....
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.

View 1 RepliesDatagridview - Sort Datagrid View Column With Numbers And Texts On Column Header Click?
Feb 13, 2012It 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?

Forms :: Reading DataGrid From External Program?
Aug 29, 2011I am working in windows forms with Vb.NET 2008. I am trying to read text in from an external program. So far I have been able to read text in from a standard text box or button, however I am trying to read data in from an external data grid.
When I try to use the following I get no information about the grid
ChildHandle = FindWindowEx(ParentHandle, IntPtr.Zero, "classnameofexternaldatagrid", Nothing)
Dim Hndl As IntPtr = Marshal.AllocHGlobal(2000)
NumText = SendMessage(ChildHandle, WM_GETTEXT, 2000, Hndl)
Text = Marshal.PtrToStringUni(Hndl)
Usually if it is a standard text box I will get the text data with no problem, but it is a standard data grid and there are no further sub handles to try and read from. If WM_GETTEXT wont read information from an external data grid then how would I read in the data?

Apr 5, 2011I have a project that needs to open a CSV file that is 3.7gb in size. It is data that was exported from a database (why on earth anyone would export it to ONE file, is beyond me)
Excel/Access can't open the file because it is more than 256 columns and greater than 65000+ rows. I was able to split the file into seperate files with 50,000 rows in each. I wan't to automate this and export only data by a specific state, and perhaps add it to a database or excel file, should the rows stay below the limit.
I found a project that splits the CSV file... perhaps I can just parse the data while splitting the file.
