DataGridView Cell Borders - Bottom Border Of The Cell Disappears?
Dec 23, 2011Have 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.
[code]...
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.
Make DataGridView TextBox Cell A ComboBox Cell When It Has Focus
Dec 23, 2011I 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."
Private Sub dgvCalculatedResults_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles dgvCalculatedResults.MouseDown
Dim ht As DataGridView.HitTestInfo = Me.dgvCalculatedResults.HitTest(e.X, e.Y)

View 1 RepliesIn DataGridView, Moving From One Cell To Other Cell
Mar 2, 2009I 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.

Nov 6, 2010I 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

DataGridView Checking For Errors?
Mar 30, 20101. I can check a DataSet for errors with DataSet.HasErrors and I wonder how to check the same thing for a DataGridView.
2. Coming from MS Access I am not used to batch editing a dataset via a datagridview for instance. Think of a multi user Windows forms application / SQL Server setup. So I wonder if it's ok to just save the data after a row has changed, edited or deleted and not wait till all modification are done and then do a batch update?
Checking Combobox Values In Datagridview?
Nov 4, 2008I want to check if two combobox values are equal. The comboboxes are in a datagridview.I found you need to use datagridview_EditingControlShowing to add a handler to the comobo boxes for selectedindexchanged. I can do this with this code.
Code:
Private Sub dgridRegisters_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles dgridRegisters.EditingControlShowing
Dim combo As ComboBox = CType(e.Control, ComboBox)
[code]....
However, the message box comes up for every combobox in my datagrid when I change the index, not just the cmbPort2. I would like to have something like this...
If cmbPort1.selectedindex == cmbport2.selectedindex then
'do something
endif
..but it doesn't seem possible.
Checking To See If A Value Has Been Changed In An Unbound Datagridview?
May 7, 2012I have an unbound Datagridview which gets its data from an array from an Excel sheet. I give the user the chance to amend this data in a Datagridview. I then need to know if the user has changed this data before processing it further. I have in vain, tried to use IsCurrentRowDirty, IsCurrentCellDirty, looping through DGV matrix etc. It seems that because the DGV is not bound to a dataset then the normal properties like HasChanged and the 2 above don't seem to work. Here is my attempted code which is not working:
Dim DGRow As DataGridViewRow
Dim DGCell As DataGridViewCell
For Each DGRow In DGV_ReviewDetails.Rows

View 1 RepliesChecking The File Path Of An Image In A Datagridview?
Apr 10, 2010I have a datagridview with a bunch of columns, one of them being an Image type (DataGridViewImageColumn).What I want to do is basically check to see what the file path of the image in one of those cells is.
I've tried doing like:
If (DataGridView1.Item(7, Number).Value.ToString = "some path" then
'do stuff here
End if
but it always says DataGridView1.Item(7, Number).Value.ToString is just "System.Drawing.Bitmap", instead of the actual file path of the image in the cell.I've also tried the above, without the .ToString, but I get an error saying System.ArgumentException was unhandled (Argument 'Prompt' cannot be converted to type 'String'.)

DataGridView Image Cell Losses Resolution If Cell Size Is Smaller Than The Image Size?
Apr 30, 2012I have just found that if a DataGridView image column's size (height & width - in pixels) is smaller than the image's original size (in my case all images are exactly 180 x 180 pixels) at the time the cell is populated then the image is automatically being converted to a lower resolution I assume to fit the image completely within the size of the cell). How can I stop the automatic scaling of the image?
The image below show the same file displayed twice, both at 60x60 pixels ('Thumbnail' column) and a blowup of the image (PictureBox populated via the CellMouseEnter event) to it's right. You'll notice the resolution of the first blowup is far less the the second. so, what made the difference in the resolution of the blowups is? In the second blowup's case I'd first stretched the image column's width to ~180 pixels and set the row height to match (via the ColumnWidthChanged event) then populated the DataGridView then stretched the image column to 60 pixels (its minimum).

View 6 RepliesDataGridView - How To Set Cell To NULL
Mar 23, 2012I have several date fields in a datagridview, in sql these are saved as navchar fields. If the user needs to clear the date they can do so by highlighting the field and pressing the delete key. This clears the date no problem, unfortunately it sets the field to Nothing or "" (a blank). I need it to set it back to NULL for reporting purposes.
Here is the relevant part of the code:
Private Sub dgvWeldingLog_CellEndEdit(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgvWeldingLog.CellEndEdit
Try
If dgvWeldingLog.Columns(e.ColumnIndex).Name = "dgvtxtDateWelded" Or _
dgvWeldingLog.Columns(e.ColumnIndex).Name = "dgvtxtFitCheck" Or _

If there is an error in the data entry then the form cannot be saved. When I trap DBNull.Value is says it is equals to "Nothing" and not "NULL".
