VB2008 Get The DataGridView CellMouseDoubleClick To Fire When A User Double Clicks On A DGV Cell?
Oct 29, 2010
how to get the DataGridView CellMouseDoubleClick to fire when a user double clicks on a DGV cell.I currently have both DGV.CellMouseClick & DGV.CellMouseDoubleClick implimented in my code.The DGV.CellMouseDoubleClick never fires and the DGV.CellMouseClick always fires. The only exception is when I position the cursor between DGV cells and get the double arrow. If I double click with the double arrow then I get the DGV.CellMouseDoubleClick to fire.I need to take different actions for users RT-Click, RT-Dbl-Click, LT-Click and LT-Dbl-Click.

I looked everywhere for this but not sure if it can be done. Is there a way to fire events when a user clicks a specific tab. Here is the image to show it better:I am trying to have the program execute a special function when the user clicks on customer info.
I have a problem with a Save button on a toolbar firing the click event twice if the user double clicks the button as opposed to single clicking.Disabling the double click on the toolbar itself seems to make no difference as it is the actual save button that is being clicked twice.I have tried setting a Boolean to stop the event firing twice but it is just too quick!I didn't have this problem with my code before as the server call was not async... and reverting back is not really an option.
My code is as follows:
Protected Sub tlbOrdQuot_ButonClick(ByVal sender As Object, ByVal e As System.Windows.Forms.ToolBarButtonClickEventArgs) Handles tlbOrdQuot.ButtonClick
If I add a WindowEvents_WindowActivated handler to my Visual Studio 2005 Macros EnvironmentEvents module, I get a weird side-effect: when I click from one window to another in Visual Studio, that click is treated as a double click.
I process single- and double-clicks on a listbox in VB .Net 2005; I use single-click to just select a particular entry and double-click to select and open the entry. I want to discard any other type of click, especially triple-clicks.
In my form I have a text box (txtJobNo) , a Find button and a dtagridview to display the record for a unique JobNumber. Everything works fine to retrieve data, my problem is the display part in the datagrid view, it replaced the first record. I want to keep all records in place until I am done and then insert all those records in a new table. Please HELP. Please find my code below:

If a user clicks the blank row at the bottom of a DataGridView and moves focus away from the DataGridView, the row click in now is in a state that indicates a change is made to that row.
Is it possible to tell the DataGridView to un-mark this row as being changed?
Is it possible to reset this row when focus is off the DataGridView?
We are using the following event handler to alert the user if the Invoiced On is left blank:
Private Sub dataGridViewPayments_CellValidating(ByVal sender As Object, _ ByVal e As DataGridViewCellValidatingEventArgs) _ Handles DataGridViewPayments.CellValidating
[Code].....
Looks like we need a way to stop this from executing if the user simply clicks in the grid then clicks somewhere else in the form.
I want to know if VB.Net already has a control like this before I start wasting time building my own. I have a DataGridView that shows the row error symbol in the RowHeader if the update to the database is unsuccessful for that row. Currently, if you hover the mouse over the error icon it will show a default tool tip to display the error text.I would like the user to left-click the RowHeader and a small popup window will show the error text. Then when the user clicks somewhere other than the popup window it will disappear just like a context menu. do I need to build a form with no borders that has a large textbox in it, then setup an event so when the form loses focus it closes? Or does a context menu strip have the ability to support a large textbox? Or do I use a splash screen?
if could modify the following code for me so that it save data row by row from a DataGridView into SQl Server. Currently, the code saves data from all rows at time instead of saving only the recently added data in a row or rows when the user clicks a button.[code]...
I have a DataGridView where Cell_Validating is being done. I have a Cancel button on my form that allows the user to exit out of the DataGridView changes. The problem is that if a cell was currently flagged as in error, I cannot exit and remove columns from the DataGridView. I get the following error: Operation did not succeed because the program cannot commit or quit a cell value change. Is there a way to cancel the validation once the focus has been removed from the DataGridView? Here is my Cell_Validating
I want to be able to delete records from my database and have this piece of code to do so: Dim myConnection As SqlConnection Dim myCommand As SqlCommand Dim ra As Integer myConnection = New SqlConnection("connectionstring'") myConnection.Open() myCommand = New SqlCommand("DELETE FROM player_table WHERE player_ID = 1", myConnection) ra = myCommand.ExecuteNonQuery() MessageBox.Show("Player Deleted") myConnection.Close() But I want let the user actually select one of the cells displayed and delete that.
I validate a DataGridView with the CellValidating-eventhandler.That works fine. However, I want to avoid validating when the user presses the Cancel button. In the sequence validation occurs before the event CancelButton.Clicked.
I would like to fire an event when double clicking on a listview, but more specifiquelly in the blanck area (where NO item exists)I have read from this msdn page :
Quote: The mouse pointer must be over a child object (TreeNode or ListViewItem). how to fire the event another way ?
I am trying to trigger a tool tip when a user enters a cell in a DataGridView and starts editing it. The idea being that I want the user to know to hit the Return key after they are finished typing in a string in the cell. I only want the tool tip to show when the user is editing a cell in columindex 1.
The following below does note seem to be working. Private Sub dataGridView14_CellEnter(ByVal sender As Object, _ ByVal e As DataGridViewCellEventArgs) _ Handles DataGridView14.CellEnter 'Only care about columnIndex 1 If e.ColumnIndex = 1 Then [Code] .....
I need to record the screen when my user clicks start, and stop recording when he clicks stop.I've searched for a while on this subject, and I have found nothing.I want to do this without adding any files to my project, I just want to use some built in function in Visual Basic, and start recording, or even take a snapshot and add it to an AVI file or something...These are some sites I have found:

This code is in VB6, but I am not sure how to even start using it?
I'm afraid this is a very simple question, but I can't figure it out... I hardly ever use the DataGridView (usually use a third party grid) so I never needed to do this before.Anyway, I have a DataGridView that is data-bound to a List(Of SomeClass). The grid is not ReadOnly, but I made every column ReadOnly except the very first, which is a boolean column so it displays a checkbox. This way, the user cannot edit any cell value, but he can check/uncheck the checkbox in the first column.
What I need now basically is an event that is raised when the user (not programmatically) changes the value of this checkbox. I also need to be able to retrieve the bound item from that event (from the row number I think?) but that should be no problem, I hope.Anyway, there's a bunch of events that looked promising but all have something I don't want:
1. CellBeginEdit - Fires before the checkbox value has changed, so can't use this.
2. CellEndEdit - Only fires after the edited row loses focus. I want to save it back to the database as soon as the user changes the checkbox value!
3. CellValueChanged - Same problem as nr 2.
I'm sure it must be possible for me to react as soon as the user changes the value of the checkbox? How can I do this?
how can i read an excel cell in VB2008?1) i do not have to open MS excel.2) i want a message box to pop up the data in the cellfor example, the data in cell A5 is 586when i press a button, a messagebox will show the data in it.
Have this code so that when a checkbox in a column of my datagridview is checked, then the corresponding cell in column 2 (of the same row the check box is in) will turn blue with font color white.
[code]...
I'd also like to add a line so that as well as the cell going blue, the bottom border of the cell disappears, so cellborderstyle = none.
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)
I have a user control (SomeUserControl), that I am using in a Main Window. I write my application entirely on SomeUserControl, and Main Window is hosting SomeUserControl and nothing else.
Right now I have a shutdown button (in SomeUserControl), that is supposed to close the Main Window. The reason for this is that I do not want anything from SomeUserControl to close the application itself, but to fire an event from SomeUserControl, and Main Window receives it, and Main Window will close the application instead of SomeUserControl.
How do I do it? I am not familiar with the concept of creating and handling custom events, so if someone could explain it in words and in code as an example, I will be very grateful to you!
Edit: Here's my code so far.
(in Window 2)
Public Event CloseApp As EventHandler Private Sub CancelButton_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles CancelButton.Click DialogResult = False
[Code]....
I want to close the application when I click cancel in Window 2, but I don't want to do it in such a way that Window 2 closes itself, but by sending some notification to Main Window, and Main Window closes the application.
I am creating an application for a college assignment called "Quote Manager" - the idea is a writer can save his / her favourite quotes, then go back to them and be able to print them.So I had this idea where all the quotes are loaded into a datagrid view on the main screen of the program and the user can double click on the quote he / she wants to load.
I don't want any code given I would also post what I have got so far but at the moment I am at work.What I want is to know how to manipultate the datagridview control so when a cell is double clicked a saved html page will load from a database.
