Make DataGridView TextBox Cell A ComboBox Cell When It Has Focus

Dec 23, 2011

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."

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)

VS 2008 Set Focus (new Currrent Cell) Setting Focus On Specific Cell In My Datagridview1

Nov 7, 2009

I am having problem setting focus on specific cell in my Datagridview1 . On Form1 when clicking on cell 3 in any row, I am callig a Dialog1. However, when done working with it, and closing the Dialog1, the focus returns to cell 3 in my Datagridview1 . I like to set the focus on the next cell(4) making it the current cell.

I have tryed :

DataGridView1.SelectionMode = DataGridViewSelectionMode.CellSelect
DataGridView1.CurrentCell = DataGridView1.Item(4, e.RowIndex)

DataGridView1.CurrentCell = DataGridView1.CurrentRow.Cells(4)

And few other things, I am always getting this exception: Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function.

DataGridView - Focus On Cell That Was Right Clicked

Mar 26, 2010

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

Setting Focus In A DataGridView's Cell?

Mar 16, 2010

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


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.

VS 2010 - Reading Cell Value From DataGridView?

Jun 26, 2010

I'm reading a cell value from a Datagridview, and this works fine in other projects, but not here?

Dim OldGUID() As String = Nothing
Dim X as Integer = -1
For X = 0 To Me.DGView.RowCount - 1
If Me.DGView.Rows(X).Cells(0).Value.ToString IsNot String.Empty Then
OldGUID(X) = Me.DGView.Rows(X).Cells(0).Value
End If

It fails on the line: OldGUID(X) = Me.DGView.Rows(X).Cells(0).Value
with: NullReferenceException was unhandled - Object reference not set to an instance of an object.
The Cell has a string value and during debug I see the value, but it fails anyway.

VS 2010 DataGridView And Changes Not Made To A Cell?

Apr 12, 2012

I have a DGV bound to a data adapter. I have a button that loads a form with a reference to the DGV row. When the form is loaded, it has a TextBox to type a value, that modifies one of the cells of the row. When the form closes, the cell.value is properly modified, but saving the DGV doesn't save the new value of the cell to the DB table. I'm assuming this happens because the DGV hasn't had physical interaction. Also, this particular field is a password field, so the whole column is being hidden from the view.It seems that a DGV change is noted by physically clicking in a cell and it stores some data telling the adapter there have been changes. The thing is, this is done on a per cell basis, and only if the cell has been clicked. Well, this cell is hidden, so even though the value will be changed, you could never click or select that cell.Is there any other way to force the DGV to accept changes made to it from outside actions of just assigning the cell.value from a button click and not phsyically changing it in the DGV?

VS 2010 Datagridview Cell Formatting?

Jan 21, 2012

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?

VS 2010 Select A Specific Cell In A DataGridView?

Jan 5, 2012

I am making a program which remembers my last selected row in a data table. I have done this by adding a column with a CheckBox, upon CellClick the CheckBox is checked, and upon ellLeave it is unchecked and the new cell is checked, after every action a Update command is run. There will never be more than one row with a checked cell in the DataGridView,however, the data table is in a relationship with other tables, so there may be more checked cells in the data table itself. My problem now is selecting the row with that cell when I open the program and when changing between other data tables and back again.All solutions I found on selecting a specific cell in a DataGridView are referring to index numbers, and in my case I need it to find a data value in a column, I do not know the specific row, only that one row contains the value of True while everything else is False.
