I have a textbox on a form that when it loses focus it updates other text boxes on the form. But before it updates the other textboxes I check the input value in the textbox lostfocus event if it is undesired I return focus to the the textbox and alert the the user with a msgbox. However where my problem is, is that when the cancel button is clicked I don't care what the input in the textbox is because the changes are being canceled but if the value is undesired the it keeps returning focus to the textbox instead of canceling the changes. Is there a way to see what control was clicked on before or in the lost focus event? Can't seem to figure it out tried enter and leave events but no luck!
So for example something like this...
Code:
Private Sub TextBox1_LostFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.LostFocus
If Control that was clicked <> btnCancel then

On top of my page I have a button called btnViewRecords. When the User click on the button I want to set focus to another button or label further down on the same page. How can this be done.
This code does not work for me..............
btnTheRecords.Focus()
or
lblHeader.Focus()
Even if my code did work, i dont want to reload the page every time.
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.

View 2 RepliesI 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.
Is there a more efficient/easier way changing the backcolor of a control when it has focus and lost focus? Let's say I've got 10 text boxes. Right now I would have 20 different events...10 for Enter event and 10 for Leave event. Of course, entering would change the back color to "green" and leaving would change it back to "white".

I have a tab in a windows form called Wafer Map that has three sub-tabs. The First sub-tab is the called Map and has a Load and Skip button. I am trying to set the focus on the Wafer sub-tab on the Load button click. This is the following code I have tried to use.

View 1 RepliesI have a Visual Basic Program that, when I enter data into a textbox, uses LEAVE events to update it. However, it will not update until I go to another textbox or press a button or other similar control.This also happens when using the LOST FOCUS event.How can I make the textbox update (be it doing a financial recalculation or some other custom function) happen when the user clicks/tabs out of the textbox and NOT having to click on a button or into another textbox?Do you recommend having a separate button for performing the custom functions?

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?
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.
I need to dynamically show/hide a form without loosing focus from the original form. How to do this?.
View 1 RepliesI 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 :

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 have a couple of TextBoxes on a Form and also a RichTextBox control which is associated with a ContextMenu1. Now, while my MouseCursor still blinks friendly in one of my TextBox controls, I right-click the RichTextBox and get surely my ContextMenu1. However, this ContextMenu won't do me any good unless I first left-click my RichTextBox in order to set my cursor in there and then right-click again to open the ContextMenu. I've tried to work with RichTextBox.Focus() and also with something like ... If

This should be fairly basic but maybe the search terms are too general to find relevant answers.I have an MDI form with a conventional toolbar. When I open a small non child form I want to set focus back to this main form so the user can click the help button on the toolbar if necessary.
Tried frmMain.Select() and frmMain.ToolStripButton0.Select() at end of small form load but it doesn't work. The user has to click the help button twice, once to select it and once to open it. A minor problem but annoying.
I have a nested custom control that I need to set focus on. I have it all internally wired up to automatically set the focus when the form loads, but when it comes up on screen, the designated accept button for the parent form is in focus instead. Even when is disassociate the accept button it still does not set correctly. How can I ensure my desired control gets focus.
