Setting Focus On DataGridView Control Programmatically In Visual Basic?
Aug 10, 2009
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.

1. I have a DataGridView box, that is connected to a MySQL database via the 'Data Source'. I am trying to do the datagridview1.rows.add("info here"), however i receive an error i cannot do this programmatically. I DO know the code to post to MySQL via the "insert into" la la la.However, I was curious if I can do this via the datagridview a bit..easier/simpler, such as a "datagridview1.rows.add(stuff)" sorta thing.
2. I am attempting to make a custom control, and as with ANY control, they have their.. settings. Example, a textbox, or label, has so you can set the Text. and color, etc.Others, have it (such as datagridview) have the little icon on the control itself, where you click it, and it opens a small window with settings.

I've been asked by a local window cleaner to design a small utility that can display a grid of customer data, sort them, and then export it out as a formatted .txt or rtf file.

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.
Here is the

"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?

I have a dialog that containers a DataGridView, this dialog is opened from a parent Form. I would like the DataGridView to have focus as soon as the form is opened, so on pressing the down key would enable you to scroll down through the rows straight away. I have tried setting the tab index so that the DataGridView is the first selected item in the form. I have also tried calling the DataGridView.Focus() method in both the dialog constructor and the Form_Load event. I have also tried setting the

Is what I want to do is take those image urls and somehow feed them into a datagridview, so that the user can scroll through the images and choose the right one.
Here's what I have so far
Code:
If item.IsSetLargeImage() Then

I am currently translating a windows form application, written in VB6, to a webpage written in Visual Studio 2010. In VB6 it is easy to find out which control has focus on the form using '.getFocus()'. I have come to the conclusion it is not that easy, if at all possible, in vb2008.

I'd like to make a textbox that accepts only numbers, but not integer, but rather double.I've read here about e.Handled = Not Char.IsDigit(e.KeyChar) and it works, but again, it can be used only for integer, since it declines decimal point.Another thing I've read here is If Not Double.TryParse(TextBox2.Text, value) Then .... and it would work fine, except that it allows only decimal comma instead of point.
