I am entering data in a dataGridView, I have a column named with 6 characters.The first 3 characters are always "HHH"When I enter in this cell, Is there any way to put automatically these 3 characters and start to write in the fourth one?

I have a DataGridView and have the AutoGenerateColumns property set to false, but the when I build my project the columns are Auto Generated.
I can see the property set to false in the Designer.vb code for the Form.
I've had this problem before and I'm not sure how to fix it.
All fields from my class objects are added to the columns collection of DataGridViews, when the forms or custom controls that contain them are viewed within the VS 2005 designer. I haven't been able to figure out how to stop the designer from auto-adding all of the fields found within the bindingsource object.
View 6 RepliesWhat I'm working on is a video rental project in visual basic 2008. I have a local database which contains info on DVDs, Members and a table for current rentals.The columns i have in the current rentals table are:
MemberID | DVDID | DaysOnRent | DateRented | DueDate | Overdue | TotalPrice
I have this data displayed in a datagridview, but the user adds it through a seperate form (called add a rental) with a 'details' view of the table on it. I've written code to automatically determine the TotalPrice and DueDate of the DVD in the add a rental form.
The Problem:I don't know how to get the database to automatically detect when a DVD is overdue (when todays date is greater than the DueDate).I want it to check it in the column "Overdue" (which is boolean)..so basically what I'm asking is how do i update the overdue column automatically depending on whats in the DueDate?

Now that I figured that out I was going to try and place the data in a specific location. On my application I have a datagridview set up with 4 columns. What I would like to do is put column A of the excel file under the 1st column of the datagridview and column C of the Excel File in the second column of the datagridview.

I finally got this code to work:
vb
Dim path As String = OpenFileDialog1.FileName
Dim myDataset As New DataSet()
Dim strConn = New OleDbConnection("Provider=Microsoft.ACE.Oledb.12.0;Data Source=" & path & ";Extended Properties=""Excel 12.0;HDR=YES;IMEX=1""")
Dim myData As New OleDb.OleDbDataAdapter("SELECT * FROM [Sheet1$]", strConn)
myData.Fill(myDataset)
DataGridView1.DataSource = myDataset.Tables(0).DefaultView
Now that I figured that out I was going to try and place the data in a specific location. On my application I have a datagridview set up with 4 columns. What I would like to do is put column A of the excel file under the 1st column of the datagridview and column C of the Excel File in the second column of the datagridview.
So replace:
vb
DataGridView1.DataSource = myDataset.Tables(0).DefaultView
With:
vb
DataGridView1.columns(0) = myDataset.Tables(0).columns(0)
DataGridView1.columns(1) = myDataset.Tables(0).columns(2)
Obviously this doesnt work, and something tells me I might need a for loop to import the data, but I have never imported information from an Excel file before and to make it worse I have never worked with datagridviews before so I have no idea how to go about this.
I would like to do something like this if I could:
vb
For x = 1 To xldoc.rows.length - 1
DataGridView1.Item(0, x).Value = CType(xlDoc.Cells(0, x + 1), Excel.Range).Text

View 2 Replieswhat's the best way to add some space between some columns, just to aid the user to read/understand the data (i have more than 50 columns).In this particular case i'm using a data bound dgv and one approach that i'm using currently, it's in the SQL statement add a new column named SPACE1, SPACE2, etc...Something like:
SQL
SELECT col1,col2,NULL AS SPACE1,col3,NULL AS SPACE2...
I know that i can add columns at runtime, and handle the cell paint event to change the left and rigt margins... But i don't know what option should i use, does anyone know a better way or in the above three it's the best one?
So i have a datagridview with two combos, when the form it's created i fill the first one with all the MainValues, and the second one with all possible values for the MainValues (called SecondValues) (1..N).Now my issue, when the user selects one value from the first combo i want to fill the second combo with all values related to the selected MainValue, i can do this for example by filling the datatable again with a parameter that filters the data, but if the previous rows have different main values, the dgv throws errors because it doesn't find the binded ones in the new filtered datatable.
How can i handle this? One datatable for each line?! Other thing, i'm using the SelectionChangeCommited event for handling the values change (in theEditingControlShowing), but if the user uses the keyboard to select the values the event doesn't behave in the same way or the way that i need. The values in the combo are numeric values (1001,1020,2010,3010), when the user select one of the values, i need to fill another cell in the same row with the number selected plus some string, example combo:1001 cell:1001XPTO. So if the user presses 1 in the keyboard the combobox selects the 1001 and fills the cell with 1001XPTO, but if i keep pressing the keyboard to select the 1020, by pressing 0 and 2, i get the 1020 selected in the combo, but the cell remains with the 1001XPTO.
I have a standard DataGridView. One of the columns is a DataGridViewComboBoxColumn. When I select one of the ComboBox items, I want to trap the change and add additional columns based on the item selected in the ComboBox. I've tried using CellValueChanged for the DataGridView column, and a bunch of other events, but none of them is fired when the DataGridViewComboBox value is changed. What event can I trap to make this happen? Right now as I said, I am using CellValueChanged, but of course the event doesn't fire until I click on another cell...

I am working with an Unbound DataGridView. I would like to vary the contents of a second combobox based on what is selected in the first. I have code to add the columns and populate the first combobox, but I can't figure out how to do the second one since it can (and usually will) have a different list for each row AND the list must change when the selection in the first is changed.

Is there a way to programmatically send information from a text box into specific columns in a DataGridView? I tried
vb.net
Column1.Text = TextBox1.Text
and it obviously does not work.
I want to be able to have a dozen or so text boxes be emptied into separate columns in a row of a datagridview. This way the text boxes can be cleared and have new values entered then save the new values as a second row in the datagridview. This is so my VB gui which which runs everything through an old cmd line program, can do batches instead of one run at a time.
The problem is I have absolutely no idea how datagridview works. I've tried searching google and only found some vague things and stuff about databases. I also tried the MSDN library and that was of no help either, couldn't find anything on simply adding stuff and if I had it'd probably be to complicated to be of use to me.

View 5 RepliesI have an access query which plays flawlesly in Access.I want to use it as a source for a datagridview i use in one of my forms but....given the fact that is a rather big query with some "like" and conditions like ">3" and so on AND the fact it uses tables from 3 different mdb (not to mention is bases on other queries...i 'ill try my best to fix this) what is the best approach .
1st case .Can i retrieve the data simply with NO oledbparameteres and NO " select * xxx where yyy like 'd' ".I think there is a issue with the Oledb connection that "omits" them.To explain better the query right now with the filters in access returns 3 rows, without the filters 30 rows,can i get just the 3 rows to do my job... 2nd case . How should i fill a datagridview using tables from 3 different mdbs.If you can show me an example it would be life saving.
I'm fairly new to VB.NET but have been programming for a while. Anyway, for the life of me I can't figure out how to properly populate a datagridview in .NET. I am using VS 2010.

I am working on a project that allows the user to search the database for particular records, then passes the record that the user chooses to the main form to be manipulated or changed.

This is the code for the event that fires when the user presses the button to return the selected row:
