How To Change Cell Original Value In Formatting Event Of DGV
Aug 25, 2011
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 ?

Is there any way so I can get event when moving cursor in excel sheet. What I meant by that if cursor is in cell A1 then I move to B1 at that time I want cell change event should fire. At the movement I am able to get event when you change the cell value and press enter then I can get the cell change event.

I handle the validation in the CellValidating event, and if the cell is invalid display an error message, then cancel the exit of edit mode. However I would also like to erase the content of the cell currently in edit mode.

I am attempting to copy the value of the TimeStamp in cell A6 which has the NOW() formula into cell A5 Based on a change in Cell A4. The catch is I don't want it to update every time the sheet is recalculated due to updating links in other cells on the sheet. ONLY when Cell A4 Changes. What do I do?

The event handlers in my parent class are never called though the events are raised in the child class.
The Code:

Public Event checkboxchangedEvent(ByVal checkbox1 As Boolean, ByVal checkbox2 As Boolean)
Private Sub checkboxchanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged, CheckBox2.CheckedChanged

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?

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.

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 am trying to reference the KeyDown event from a independent sub procedure and have it loop back into original independent sub procedure. Starts off in Independent sub procedure (DisplayAction - which then calls KeyDown Event) Goes into KeyDown event (KeyDown then calls DisplayAction) Goes back into original sub procedure (DisplayAction) and the loop continues. * Steps 1 and 2 work just fine in my code. Step 3 is the problem. My program does not loop back into the independent sub procedure.

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 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 am throwing some data out into Excel and am having some formatting troubles. I have 5 columns (date, time, a long number I don't want displayed in scientific notation - text is fine, text, text). I can get it all working with numberformat, however I have to do them different ways.
Date works this way cell.numberformat = "m/d/yy" and it formats it to say 3/1/11
Time works this way cell.numberformat = "h:mm AM/PM" and it formats it to say 8:07 AM
For the long number cell.numberformat = "@" and it doesn't change the format and it gets displayed in scientific notation
BUT if I use cell.style.numberformat = "@" it works as it should, but it messes up all of the date and time cells. Apparently when you use style.numberformat, it doesn't just apply to the cell you're working with. If I try using style.numberformat with the date and time formats, they don't change and are entered as if I didn't change the format at all.

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

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 this code in the onKeyDown event of the datagridview.
Private Sub DataGridView1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyDown
Select Case e.KeyCode[code]....
This works. When the Enter button is pressed, it acts as the TAB button.The problem I am having is this only works if the datagridviewer is selected.As soon as I enter data into a cell (A cell is selected) the code wont work as it is not set for the cell keyDown event. The event does not exist, so I have to somehow create it.

I have a WPF RichTextBox which contain in its FlowDocument both text and images. I need to iterate through the text's words (those which builds the text which the user see on the screen) and change their content and formatting. For instance, change the word "room" to the word "home", applying to the last a red color.
I need to change words whether they are formatted or unformatted.For instance, if a word is in Italic, colored, or just regular black text, it makes no difference for me.Each word will be replaced with one which have about identical length, so I don't want that this operation will effect the general page layout. All images and other objects should remain at their positions.It is preferred that the process of this operation will not be visible to the user. Only its result should be visible (i.e, no visible selections of text).If this operation can be done either directly on the FlowDocumet or with properties/methods of the RichTextBox, the simple one is preferred (but exmaples for both will be ideal).
