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.

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

[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.

Setting The Focus To A Particular Cell In Datagridview?

Mar 11, 2009

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.

Here is the

-----------------------------------------------------------
Private Sub DataGridView1_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles DataGridView1.CellFormatting

[Code]....

"An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll" with the note about infinite recursion.

What have I done wrong and how do I scroll through to automatically set the focus?

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)

[Code].....

IDE :: Force The Cell Value To Be Blank And Focus Back On That Particular Cell And Try Again?

Jul 28, 2010

Datagridview . in cell validated handler and I have the column,row for the cell that I just checked on. If the cell contents are bad, I want to force the cell value to be blank and focus back on that particular cell and try again.The code i've tried simply moves to the next cell in the grid instead of staying where I want it to be. Surely there is a command to focus and put the 'cursor' back in a particular cell.Some sample code I'm working with:

MsgBox(
"Invalid Job#, Correct or DIE!")
JLgrid.Item(0, Row).Value =

Datagrid New Row Cell Validation - Validate Empty Text And Indicate Error On Cell?

Jun 1, 2010

The problem is that if you never enter anything into a cell for a new row then that cell is never validated. This is a problem because I have columns that should not be null. I am doing the check in the row level validation and storing the information about which cells are empty that should not be empty. The row level validation works fine and the row level validation error indicator goes on,(red exclamation mark at the beginning of the row) but I also need a visual indicator on the individual cells that are in error.

I am thinking that setting the HasError property for the cells that are in error should cause them to display n error style (the default red border). Is there a way to this this either from XAML (perferably) or from code?Alternatively I could cause those cells to re-validate when the row editing is finished. Does anyone know how to do this?

Prevent Moving To An New Cell In Datagrid If The Current Cell Is Empty

Aug 2, 2011

I have a datagrid that will be accepting data from an external measuring device via the serial port. The grid is also open to editing records as well. Part of the process of making this grid user friendly is to intercept the "enter" key and move to the next cell until there is a value in the cell. This is only for some cells, other cells can be blank. I have worked out how to intercept the "enter" key from another post on this forum. Here is the code:

.net - Setting Focus On The Parent?

Jan 6, 2010

I want to unfocus(leave) the texbox when I click on the usercontrol/form(focus the usercontrol/form instead): I do the following on the UC/form:

Protected Overrides Sub OnMouseClick _
(ByVal e As System.Windows.Forms.MouseEventArgs)

Me.Focus()
End Sub

Why does it not work on the child textbox, but works very well on the non-child one(focus on textBox2 then click on the panel removes the focus from the textBox2)?

Asp.net - Setting The Focus To A MsgBox Object?

May 20, 2009

In my application, a user clicks a "save" button and is then presented with a MsgBox confirmation simply stating "Are you sure you want to save?", or something along those lines.

It's been hit or miss, but occasionally, this MsgBox will load behind the browser rather than be the center of attention with focus. How can I stop this from happening?

C# - Setting External Application Focus?

Dec 17, 2009

In VB.NET, you can set focus to an external application using

AppActivate("Windows Name")

or

AppActivate(processID As Integer)

Now this works fine if you do for example:

Dim intNotePad As Integer = Shell("C:WINNTNotepad.exe",
AppWinStyle.MinimizedNoFocus)
AppActivate(intNotePad)

But when I do:

For Each theprocess As Process In processlist
If InStr(theprocess.ProcessName, "DWG") Then
strProcessList += String.Format("Process: {0} ID: {1}", theprocess.ProcessName, theprocess.Id) + vbCrLf
AppActivate(theprocess.ID)

[code]....

then it doesn't find the window, even if it's open and even if it finds the window using the window title.But I need it by process ID.How can I do that?I need it to set focus on a 3rd party installer in a windows installer setup project.

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.

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

PropertyGrid, RefreshPropertiesAttribute Cell Focus?

Within my PropertyGrid I have decorated a class with the following attributes:

Code:
[Category("Category 1"),
DisplayName("Part Number"),

Dim PN1 as String

The problem is that when PN2 is changed in the PropertyGrid, it causes a refresh of all cells. Since both properties have the same DisplayName, but different Categories, the focus is set to PN1 and not PN2 after PN2 is edited.
