VS 2008 Datagridview Cell Data Formatting?
May 24, 2012
I am working on a vb6 to vb.net migration project using vs 3.5. I have a datagridview.in a particular cell of this grid, user has to enter only numeric data. but after user enter data, itshould become concainated with a $ symbol (eg: if user enter 34, the cell value should become $34). And if he/she presses the hyphen ("-") in the key board, the data (ie. $34) should become -$34 and if again presses the hyphen button in key board, the data should become $34.

I'm trying to format a column of numbers is a datagridview and I'm having some problems. This is the code I'm using: dgv.Columns(5).DefaultCellStyle.Format = "n2" If the number I put in the cell is 100.50, it shows up as 100.00. If I try to edit it back to 100.50, I get a "value was either too large or too small for an Int32" error. The cell also is accepting Char data. I want to format the column so it only accepts numbers in a '#####.##' format.

I have a password column in my datagridview, and I'd like to display the characters as a * while editing and even displaying. I have the following code but when saving to the database the password gets saved as for example.:
Private Sub dgvUsers_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles dgvUsers.CellFormatting
If dgvUsers.Columns(e.ColumnIndex).Name.Equals("Password") Then

I have set a column (which is a phone number) in the designer with the following: DataGridViewCellStyle { Format="(###)###-####" }
This seems to have no affect upon the results when it is displayed. It simply displays ########## every time. Where should I set the formatting?

When a certain form (containing a datagridview (dgv)) is first loaded, the dgv cell formatting event is triggered by the line
dgv_WorkHistory.DataSource = ds_WorkHistory.Tables(0).DefaultView This successfully adds some background colour to a few cells in the displayed table. After this the next line of code is executed. The problem is that if I then try to load a different table (by choosing one from a listbox), the new table displays OK but without the desired formatting. Why?
Stepping through the code I find first of all that when I click on the listbox the dgv cell formatting event is instantly raised (immediately, even before any code in the listbox click event is executed). Why does clicking on the listbox trigger the cell formatting event?
Then, when execution reaches the line quoted above for the second time (remember it triggered cell formatting the first time round) it doesn't this time trigger it. The next line of code is executed instead. Why has the behaviour changed?

I have a DataGridView bound to a DataTable that has 1+16 columns defined as Integer.The default cell style is hexadecimal 2 digits (.Format="X2").When entering in cell editing I would like to provide to the user, the possibility to write the value in decimal or hexdacimal.Hexadecimal could be written like, for example, 0x00, 0X01, x02, XFF
Decimal like 0, 1, 2, 15For this reason in EditingControlShowing I add "0x" to the TextBox value
Private Sub BankGrid_EditingControlShowing(ByVal sender As Object, ByVal e As DataGridViewEditingControlShowingEventArgs)
Dim grid As DataGridView = DirectCast(sender, DataGridView)

I want to make a certain column of my datagridview red based on values from 2 other columns. I have a "HI" column, a "LOW" column and a "Result" Column which are all strings. Now I want to make the result column red if it's values is less than the "LOW" columns value or if it's value is greater than the "HI" columns value. I tried the following code but something is wrong because cells that shouldn't be red are red:
Private Sub dgvTests_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles dgvTests.CellFormatting
If dgvTests.Columns(e.ColumnIndex).Name.Equals("Result") Then
Dim RowValue As DataRow = TestTable.Rows(dgvTests.CurrentRow.Index)

I have a SQL database, with some "status" strings. For every status I need to display a .bmp image .
I'm displaying the data from the database via DataGridView with LINQ. In order to display the DGV I have this code:
Me.MyTableAdapter.Fill(Me.TestdbDataSet.MyStatusList)
I was thinking to add another column named "Symbol" and based on the "Status" column to format the cells of the "Symbol" column to display an image.
I edited the DGV, and add a new image column.
I created a directory in my solution called "references" where I put all the .bmp files
I don't know how to do this. My first thought was to put an expression in the DataTable Properties, but I didn't manage to make that work. Another way is to format the cells in the "Symbol" column, and again I don't know how to do that. I tried with "Select Case ... Case ... End Select" with no success.
LE: Should I Insert the .bmp files into SQL database (varbinary(MAX)) If yes, how?

I have a DataGridView where Cell_Validating is being done. I have a Cancel button on my form that allows the user to exit out of the DataGridView changes. The problem is that if a cell was currently flagged as in error, I cannot exit and remove columns from the DataGridView. I get the following error: Operation did not succeed because the program cannot commit or quit a cell value change. Is there a way to cancel the validation once the focus has been removed from the DataGridView? Here is my Cell_Validating

My code is this:
Me.Validate()
Me.CFTINVENTORYBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(CFTDataSet)
At first I can insert data into the cells and save it... but when I try to edit the same cell with data already saved in it I get this error...
sqlcelexception was unhandled
There was an error parsing the query.
[ Token line number = 2,Token line offset = 29,Token in error = , ]
I also get the same error when deleting an already saved cell with data.

I am updating my last post so hopefully someone will help. I have following code that will move a cell to the next column when hitting the enter key while doing an edit. It will even check the row at the last cell to validate data is present.
However, if there is no data in a cell and I press enter, the focus moves to the next line like it normally does. I need to prevent the user from moving or clicking on any cell until the cell they are on has data in it. Here is the coe I have used[code]...

I've been looking everywhere for an answer to a simple question, but i'm having issues, so i thought i'd join and post here. I'm having issues with a simple concept. I load information from a SQL database, and i want to add a 'Passport' link URL relating to column cells called 'name'. It basically selects the name, and inserts it into the link fields to be opened. But i cant find a way to work it. I thought i could do it with something like:

I'm developing application in VB.NET 2008. Whatever I'm formatting cell that should reflect on original value. In Cell Formatting Event, e.Value=format(e.value,"0.0") means it is formatting data but original value is not changing on cell.
But I tried like this
Private Sub DataGridView1_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles DataGridView1.CellFormatting
With DataGridView1
If e.ColumnIndex = 0 Then
e.Value = Format(e.Value, "0.0")
.Item(e.ColumnIndex, e.RowIndex).Value = e.Value
End If
End With
End Sub
It is working for normal datagridviews but if I do the same for databound datagridview , data are flickering... (i,e cellformatting event is executing always). How to change original value of cell in cell formatting event ?

I have a program that creates a excel spreadsheet and a chart on each tab from extracted data in various .txt files. Before the chart is created, two of the excel columns will end up with data like this: on column 9 and 10. I also use data (time, looks like 09:15) in column 11 that shows the time at the bottom of the chart. There are just too many digits in the output and the readability looks bad so I can also convert.
Input Output
800400047320000
825400047120000
[code]....
The chart will display those values just fine but, normally the conversion in code that I do during the placement of that data (so it reads a bit better) looks like this:
'Convert bit to Kbit
If InRate.Length < 7 Then
InRate = CDbl(InRate) / 1000 & " Kbit"
[code]....
how to make the chart work with just numbers and ignore the MB or Kbit at the end?

I'm making a data entry form using a datagridview and I want to control which cells in a row are visible. For example, I only want the first cell in a new row to be visible until I validate what was entered - then I'll either fill in the other cells with data or ask for user input.
