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?
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?

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.
Still experimenting with datagrids and ran into another problem...I'd like to sort a column displayed in a datagrid bound to an Access table programmatically. The field is a date ime type and is sorted in descending order in Access. I can manually sort it at run time but i'd like to know how to sort it with code.
I used visual basic 2008 express edition and I read the "How Do I" tutorial and I went over with it but there are still some instances I can't find or figure out and I need some assistance. I used the LinqtoSQL classes in my project, I have one database and has one table in it,now here is the output of my project.Everytime I first run my project I would be able to view all the records in the table that is inserted in the datagridview on one of my form w/c has existing records that Ive added when I input records when running but when you add new records into it and after adding the new records when you view it right away it would only display the records in 4 fields or 4column of my table and I have 8 fields or 8 columns in my table the rest are blanks but when you exit the program and run it again that's the time you can be able to view all the records in the datagridview attached on a form.I want that when I add records and view it would display all the records w/out needing to exit the program.
I have a SQL Data Base. I have created a relation between these tables. Problem is when i drag and drop it on Data grid i get only Parent table columns but i want to sea them both like this.
I've been attempting to tinker around with connecting a MS access database to a vb 2008 app. I've successfully connected and can access the data by using the add data sources tab. But what I'm trying to do is create a form that has a (1) single line text box, (1) button, and (1)multi line text box. I enter a name in the single line text box, click the button(search db), and when the info is found, it is displayed in the multi-line text box.
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.
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 know how to set sorting direction on each column in datagrid programatically, but I wonder how to do the opposite: obtain the sorting direction for a particular column.
Dim cn As String = ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Database genk.mdb;")

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 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.
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.
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
I have coded my program so that when a user clicks on a column, the data is sorted in ascending/descending order.When I go to click on a column header, however, nothing actually happens.I dont get an error or anything.Here is the code that I am using to sort the records in the GridView:
Property GridViewSortDirection() As SortDirection Get If IsNothing(ViewState.Item("GridViewSortDirection")) Then Return SortDirection.Descending
I am trying to display a football league table in datagridview. my code gets that data for each column from ms access and displays it in datagridview. I want to sort rows according to the value of the "pts" column.I've tried using using BindingSource.Sort = "pts" but this has had no effect.
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.
