VS 2008 Set Focus (new Currrent Cell) Setting Focus On Specific Cell In My Datagridview1
Nov 7, 2009I 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, 2010I 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.

Restrict Certain ToolStripMenu Items To Certain Users

View 1 RepliesMake 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."

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

View 1 RepliesC# - Save A Setting For All Users Under Vista?
Oct 10, 2009I need to save a setting which is then available to all users of the application on the given machine. It needs to work on Vista/Win 7, and the application won't be started as administrator.
Can't Save to program directory as the Program Files folder is protected on Vista Can't save to HKEY_LOCAL_MACHINE as that's protected too Can't save to server or web-service Where can I save data to? Even if the application rights were somehow elevated during execution, the registry is now virtualised in Vista - and so I will end up with a special HKEY_LOCAL_MACHINE which is actually only for the current user.

C# - Setting External Application Focus?
Dec 17, 2009In 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.
