Focus Retained From One Datagridview To Another?
Jan 24, 2011
I can enter data into the grid and have an working update command when the row leave event occursProblem comes when I click into the other datagridview the previous cell in the previous datagridview highlights and the cell in the datagrid view I click on highlights I can edit data in the other datagrid view but as long as that highlight is on in theprevious datagridview I cannot shut down my program with the close button. I must first go back to that other datagrid view and click on it once to lose that highlighted cell and then close. I don't get any errors during this time just can't shut down program.

A user logs in by inserting their user id and password.If they don't have an email address assigned to their login details they are asked to submit one before they can continue.They then continue to the home page in a logged in state.The trouble I'm having is that the user id and password are not retained when they submit their email address so the login fails.
Here's the code...
Dim userid as String
Dim password as String
Sub Page_Load(ByVal Sender as Object, ByVal E as EventArgs)

I have two functions that return a dollar amount but one of the amounts extends out to more than 2 decimal positions. So I'm trying to round it to two decimal positions and for some reason after the amounts are added together it goes back to extending out more than 2 decimals. I have tried several things. Currently I'm trying to even use a string variable in-between conversions to see if I can get rid of the decimal values but it's still not working.
Here is the first function.
Public Function dTotalDollars(Optional ByVal iClassAccountIndex As Short = -1, _
Optional ByVal iBreakdownCode As DOLLAR_AMOUNT = DOLLAR_AMOUNT.ALL_DOLLARS) As Double
Dim dAmount As Double
[Code].....
Then after the second call it's showing in debug mode that dTotalCalcDollars is going to return 2272.37, but once it adds it to dAmount the amount becomes 28094.739999999998 instead of 28094.74.

I have VB.Net Exp 2008 with SQL Exp 2008, on a windows form I have 6 databound textboxes and 6 unbound textboxes, in the bound textboxes the records show as the bound dataGridView rows are selected, in the unbound textboxes is where I will enter the new record to be sent to the database. Added an SQL database in the designer which gave me a dataset(MdDB1DataSet) and a tableAdapter(MdTBTableAdapter). My problem is with adding, updating and deleting records. The add records button addes it during debug to the dataGridView, but does not return when I debug again. So this means it is not added to the database. The update button updates the fields in the DGV, but no record was retained.
Add Record button:
Dim nr As DataRow = MdDB1DataSet.Tables(mdTb).NewRow
nr(0) = Trim(txtAdd1.Text)
nr(1) = Trim(txtAdd2.Text)
nr(2) = Trim(txtAdd3.Text)
nr(3) = Trim(txtAdd4.Text)

I have a datagridview that I have put a ContextMenuStrip1 on. I would like it to remove a row in the datagridview when the row is right clicked on and they click on "delete row". I have the delete working and the menu is showing up but this isn't firing when you right click on the datagridview.
This is where I am setting the row to edit:
Private Sub ModifyRowToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ModifyRowToolStripMenuItem.Click
If Not datagridview_TagAssignment.CurrentRow Is Nothing Then
[Code] .....
I am always ending up on row(0) and never the row I right clicked on.
Private Sub datagridview_TagAssignment_CellMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles datagridview_TagAssignment.CellMouseClick
If e.Button = Windows.Forms.MouseButtons.Right AndAlso e.RowIndex >= 0 Then
datagridview_TagAssignment.Rows(e.RowIndex).Selected = True
End If
End Sub

I have a split container in my vb program that has 2 buttons right on top of each other in container 1. In container 2 I have a datagridview. The buttons are to mark a row as a blanket order that is in the DGV, so I'm only wanting the button enabled if the user is in the DGV. I was using another way of doing this by using the backgroundcolors of the rows like this :

I have a datagridview with a combobox column. The combobox column is populated from a collection. I begin to add data to the dgv, I select in the first row a value in the combobox and go to the second row. In the second row, when the combobox gets the focus, it appears 'V18', also the selected value before. Why? An on the other, when the combobox in the second row losts the focus, the combobox value is nothing. Why? Here are two images:

I have a datagridview. If the user adds a new row, and then clicks away from the grid. How can i stop them from doing this?
I want them to finish the row add first or cancel it. I want to then update the table adapter in the grid's leave event.
If the row validation fails, i want to display a message and re-focus to the cell in question.
The first problem i am running into is that the focus continues to go to the control that the user clicked on to move away from the grid.
How do i cancel that event?
As an example, if the grid is on a tab page and the user clicks on another tab page, i want to prevent that page from displaying if there is an error on the row that is being added to the grid.
I was hopeing for a cancel option in the lost focus event of the grid.

I am trying to set the focus in a datagridview's cell after the user enters some data and tries to tab out of the cell. I can't seem to get the focus in the cell they just edited. I can change the background color, but the focus goes to the next field in the grid. I am trying to do this in the _CellValidating event. Here is my code :
Private Sub dgvFish_CellValidating(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellValidatingEventArgs) Handles dgvFish.CellValidating
[Code]....
The function CheckSampleNumber() takes the value of the cell just entered, and checks to see if it has been entered either in the current grid, OR in the database.

I am having trouble setting the focus to a particular cell in datagridview.
I have a timetable and on initialisation of the program, it compares the time in the datagridview with the current time. If the time has passed, the row is displayed in grey, if not then it is shown in black. I then want to scroll through the datagridview to focus on the first black line.

I have a dialog that containers a DataGridView, this dialog is opened from a parent Form.

I have a bound DataGridView where the user should enter an item number in one cell, the name of this item will be displayed in the next cell, and depending upon variables of this item number, the focus should be set to the correct cell on the same row.
My problem is that I can not seem to get the focus to the correct cell.
My code so far. I am having problems with the marked line:

I have a small doubt: (VB.Net 2005, MS-Access 2007)Is it possible to add the current row from DGV to DB as soon as the row lost its focus..i.e. whenever i add a new row in DataGridView it should automatically get inserted into the database without pressing any buttons... Bcoz i need to add more new rows dynamically & hence i find little difficult in clicking the ADD button again and again to insert each and every Record.

If a user clicks the blank row at the bottom of a DataGridView and moves focus away from the DataGridView, the row click in now is in a state that indicates a change is made to that row.
Is it possible to tell the DataGridView to un-mark this row as being changed?
Is it possible to reset this row when focus is off the DataGridView?
We are using the following event handler to alert the user if the Invoiced On is left blank:
Private Sub dataGridViewPayments_CellValidating(ByVal sender As Object, _
ByVal e As DataGridViewCellValidatingEventArgs) _
Handles DataGridViewPayments.CellValidating
[Code].....
Looks like we need a way to stop this from executing if the user simply clicks in the grid then clicks somewhere else in the form.

I want to programmatically set the focus to the last row (bottommost, its only one column wide) in the DataGridView control for Visual Basic. How can I do so?
So far, I have tried DGV.Rows.GetLastRow(DataGridViewElementStates.Selected)
without success, though I did not expect that to work. It absolutely must select that last cell. Otherwise, the application is nearly impossible to use!
Here is a screenshot of what I am making with this: [URL]..The "Paste Clipboard Contents" button only pastes into the selected cell, though I guess I could find a workaround.
