View 4 RepliesI have a WinForms DataGridView control on a form. There are two fields in this DataGridControl:
Email Address
Resolved Email Address (calculated based on the input in Email Address)
After the user inputs or changes a value in Email Address, I want the value in Resolved Email Address to update based on a separate method. What event should I tie in to so that that the Resolved Email Address cell is updated after the Email Address cell is updated?I'm not sure where to put the event because the user could do a number of things after adding/changing a value: tab to the next cell, click cancel on the form, click ok on the form, etc.
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 am adding an undo feature for a DataGridView using the Command Design Pattern. To create the EditCommand, I have to know what was the previous value of the cell, so I can re-enter it in case the user hits undo. I'm doing it using the CellBeginEdit and CellEndEdit events. With the CellBeginEdit, I save the value of the cell in a private variable and at the CellEndEdit function, I use the saved value to create the EditCommand. It's working fine, but I wonder if there is a more saner way to do it. Maybe a event that holds together the previous and the new cell value. Bonus points if I could actually prevent the DataGridView from updating itself and let the EditCommand do it.
View 1 RepliesI am trying to trigger a tool tip when a user enters a cell in a DataGridView and starts editing it.

I am trying to display a custom control in a datagridview cell so that I can show nicely formatted information.
I am quite comfortable with the use of datagridview control accepting a list of objects as its datasource. I am also comfortable with populating the cell contents in the cellformatting event.
So I am planning to, instead of using a normal textbox control, button control and linkedtext control in datagridview cell, display my own custom control which is good one for displaying some custom data like, name, address, telephone, photo and others. It would be a nice improvement in my application.
I have a DataGridView and want to update the contents of the CurrentCell while the user is typing.e.g. In a cell of fractions I want the user to be able to enter .957 - As soon as the user types the . I want to programatically change it to 0. without the user being aware of the change.

View 2 RepliesI have a datagridview and in the _CellValidating event I am checking a cell to make sure it is filled in. If it is not, I want to stop editing, display a msgbox, and highlight the particular cell. Here is my code :
If e.ColumnIndex = 2 Then
If e.FormattedValue = "" Then
If Me.dgvFish.IsCurrentCellDirty Then
MsgBox("Sample Number is a required field.")

For some reason, I can't get the cell's backcolor to be filled in.
Have this code so that when a checkbox in a column of my datagridview is checked, then the corresponding cell in column 2 (of the same row the check box is in) will turn blue with font color white.

I'd also like to add a line so that as well as the cell going blue, the bottom border of the cell disappears, so cellborderstyle = none.
I have a DataGridView with several columns. One column is a TextBox column named "Status". This column can only show one of three values: 'Final', 'Ready', or 'No Reportable'. I want to have some code that would turn the TextBox cell into a ComboBox cell when the user left-clicks on the cell to allow the user to choose one of these three options. When the user clicks elsewhere or the cell loses focus I want the cell to change back to a TextBox cell.
Here is what I have so far, but the code throws an exception indicated below Plus, I don't think the code would remove the combobox when the cell loses focus.
Exception: "Provided cell does not belong to this DataGridView control."

View 1 RepliesI have a datagridview and it has 8 columns as textboxcolumns. I am handling their cell validation with cellValidating event.
My question is that if cell validation fails for 3rd column of the datagridview then the focus should move from 3rd column to 1st column of the datagridview. How can i do this?
I have tried datagridview.column(0).selected = true, when validation for 3rd column fails, but this is not working. Focus still moves to the next cell. I can stop the focus to the current cell with e.cancel=true but i want it to move to the very first cell of the datagridview.

I'm trying to add functionality to my DGV that enables the user to edit the cell data and then save it to the datasource but I'm not getting very far. Right now, I'm just concerned with the editing the DGV part.
What's the best way to do this taking into consideration: A column of type date in hh:mm format will not edit. At the moment this column won't display the new edit and if I attempt to enter and display a string instead of a hh:mm rime format, I get an error)I need to provide validation for the value that is entered.There are loads of events for DGV cells
I want to only allow editing of one column in my DataGridView, but I want to allow the user to double click on any item in the row, and when the CellBeginEdit fires, force editing of my colum. I started by doing this:
Private Sub dgvCaptions_CellBeginEdit(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellCancelEventArgs) Handles dgvCaptions.CellBeginEdit
If e.ColumnIndex <> COL_CAPTION Then[code].....
But this throws an error in the BeginEdit(False) line because 'Operation is not valid because it results in a reentrant call to the BeginEdit function.' which of course it will do, but that is what I want. Is there another way to do this?
I have a problem with the database and the DataGridView. After editing the attributes of the database you can not see changes in the DataGridView. If you connect the DataGridView through code connection is correct. What could be the reason? What could be the fault of pliu nmd_piDataSet?

I have a Windows Form VS2010 .NET 4 project with a standard DataGridView bound to a datasource on a form.
The grid has a text column that I want to be a point and edit at the character clicked to. Like normal textbox/editors when you click on the character you want to adjust. If possible I would also like to use the UP/DOWN keys to move between rows but would like the cursor to move to the same character position obviously in the same column without selecting the entire text.
I have tried a few things:
DataGridView1.ClearSelection()
DataGridView1.BeginEdit(False)
The BeginEdit just puts the cursor at the end of the text, which means another click to point to the character position for editing.
I know a Commercial grid like DevExpress defaults to editing in which you can click to the correct character position with one click but obviously costs money.
I have tried in the DataGridView1_EditingControlShowing event
If TypeOf e.Control Is System.Windows.Forms.DataGridViewTextBoxEditingControl Then
Dim tb As TextBox = e.Control
tb.SelectionStart = 5
[Code]....
I am just trying to remove the two or three clicks to get to the character position that needs adjustment.
I'm having problems editing the text of a particular column in a datagridview from the front end. The text enters ok but as soon as the cell loses focus it goes back to the old value. The datagrid view readonly property is set to false and I don't have any problem writing to the other columns.
