Using PreviewKeyDown Event In DataGridView In Winform To Navigate Using Up And Down Arrows
Nov 3, 2010
We have a winform application using Oracle DataAccessClient.There is a gridview and textboxes where we when we click on a row we can populate the textboxes to show more of the data so the user does not have to scroll horizontally.The code that does this is in the cell click event. We want to also do this if the user presses the up or down arrow. We put the code in the PreviewKeyDown event but we are getting the row that had the focus rather than the row that has the current arrow pointing to it. We searched the web at a lot of forums but we can not seem to locate how to do it. How do we move the focus to the row the arrow is pointing to in the grid? [code]

Below is code I have written to capture when the tab key is pressed inside of a two-column data grid view. The only problem I'm having is that I have to press the tab key twice for this event to fire. Would anybody know why this is.
Private Sub dgvCustomerIncludes_PreviewKeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.PreviewKeyDownEventArgs) Handles dgvCustomerIncludes.PreviewKeyDown
If e.KeyValue = 9 Then For X As Integer = 0 To (dgvCustomerIncludes.Rows.Count - 1)
If Not Trim(dgvCustomerIncludes.Rows(X).Cells(0).Value) = "" And Trim(dgvCustomerIncludes.Rows(X).Cells(1).Value) = "" Then

I have code to create a listbox and populate it, and would like the box to behave like it does when clicked, e.g. if you CLICK on "a" you see it blue and can press the down arrow to move down to "b". how do I achieve this programmatically?
Private Sub junkloader()
brandlist.Visible = True
brandlist.Items.Clear()
brandlist.Items.Add("a")[code].....
this code SELECTS it properly, but I want to be able to navigate with the up and down arrows. how do I do this? thanks.

i have a databound datagrid in vb.net 2008. This is a program where i use the double click event multipal times.. but for some reason on a new form it's not working anymore. In code behind i selected the datagrid and double click event. when i double click on teh grid in debug mode, it never fires off the event(i put a breakpoint in). I've tried several other events and none of them are firing.

I'm trying to capture the initial value of a listbox immediately after it's clicked on, and before the SelectedIndex is changed. The following was taken from: MouseDown in WinForm ListBox Kills SelectedIndexChanged, converted to VB. The ListBoxComponent Class is in a Component that shows at the top of the Toolbox.
Public Class ListBoxComponent
Inherits ListBox
Public Const WM_LBUTTONDOWN As Integer = &H201

I have a userControl11 (either in winform or wpf) which has a ValueChanged custom event. If I put it in client form and in form_load set its value to 100, it will trigger the ValueChanged event. But if I set this value inside the constructor of UserControl1 the custom event won't trigger. How can I force it to do so ?whatever the technical reason, functionally it does make sense. If the object is initializing its value from some sources unknown to the client form and the client form has a textbox bound to this usercontrol value, it is sure convenient that it could refresh its textbox at any time including when the form loads just using one single event handler. Without this the client form has to create another initializer for this bound textbox at form load.
Below the source code of my trials in winform:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;

Im making a Cinema Script Editor in VB.net. I import some columns from excel to a database, and put this data into a datagridview to edit it. i have 2 columns in the grid, with multiline like this:
Me.DataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCells
Me.DataGridView1.DefaultCellStyle.WrapMode = DataGridViewTriState.True
I need to navigate in the grid like if i were in Word, i mean, pressing the up or down arrow the cursor should move first in the lines of a cell, and when it reaches the cell end, it has to go to the next cell in the column. But now, if i press up or down arrow, it moves from cell to cell...

In words, what control can I use to set and display column and row header data then allow the user to populate the rest of the grid? The webforms gridview control will not display at all if its contents are empty. What's best practice for this kind of user entry? Do I embed an excel spreadsheet? I will also need to read the user input too.

I have a tag setup on the ID property within the Camper class. when i double click on a row in teh datagridview, i do a me.dgResults.tag and it always shows the first rows ID value. If i change the ordering within the class, it will display a different value, but it's always the first value in the datagridview. I'm missing something simple to get this working.. just don't know what it is.

The page in webbrowser2 loads correctly but when I make a change to an element it doesn't also change the value in webbrowser1 as it should.

I would like for my program to navigate via textbox1.text with multiple lines and multiple url links inside of it. I know how to make the webbrowser1.navigate via textbox1.text with multiple lines, however I want my webbrowser to navigate to each url every 1-1.5 seconds once button1 is clicked. Yes, my webbrowser1 will navigate to the specified urls via the textbox1.text (multilines) with a button click, but I need the webbrowser1 to navigate in a order sequence from top to bottom of Textbox1.text (multiplelines) every 1 second. Here is the current code that I have to navigate via multilined textbox1.text control in order sequence:

I've created a class for my game and I would like to use the arrows key to control an object on screen.
However since this is the keyDown event I've put it in the main form -form1 But it says that .Left is not part of my class since I am trying to put this on the object that was created by the class. If I put this code in my class it says that event KeyDown can not be found because it is obviously but of the form...

I am building a really complex program, and the only thing that i cannot make work right is the menu.The menu is basicaly 13 textboxes:
-txtMenu1
-txtMenu2
_txtMenu3
There is also a cursor next to the menu with up/down end enter button.When I click the down button it moves the selector one space down and up moves it up..The problem is when i click the down arrow it just moves the selector one space down, when i click it again it does not do anything. Same thing with the up arrow.The code for the down button is and the text boxes tab is in order from 1 to 13.When I reach the end (txtMenu13) and click down arrow, the selector goes back to txtMenu1. I need the selector to be blocked there on txtMenu13 so the user has to use the up arrow to go back to txtMenu1. The same thing when the user reaches txtMenu1 and tries to go up one more, he should not be able to do it.

I'm trying to sendkeys to a vt320 terminal, all keys work fine BUT the arrow keys.
For some reason which I obviously don't know, when I
sendkeys.sendwait("{DOWN}")
The terminal shows the number "2" instead. (The equivalent number on the number PAD)
If I send "{UP}" it displays the number 8. (numpad as well)
Code:
Dim p As Process
p = Process.GetProcessesByName("k95")(0)

Trying to create a custom button to reside on the desktop at:
Me.Height = PictureBox1.Height
Me.Width = PictureBox1.Width
Me.Top = My.Computer.Screen.WorkingArea.Height - Me.Height
Me.Left = My.Computer.Screen.WorkingArea.Width - Me.Width
The trouble is all the arrows point to right, and the menus open variably depending on size.
Is there anyway to make the arrows point left and make all menus open to left in same direction?
Also, Is it possible to make the width of my form autoresize to the size of a label and the image box, while keeping the imagebox at the bottom right of the screen showing the populated label to the left?

I have just made a simple application with a questionnaire. The questionnaire has all 40 questions in the same page (that was one of the specifications) which makes for quite a long form. On top of that, each question has its own group box and each group box has 4 radio buttons for the possible answers (in total 160 radio buttons).
I want the user to be able to scroll down using the up/down arrow keys. However, if he has just selected an answer, pressing the down key will only change the selected radio button (as is the expected behavior of a radio button).
How do I disable the selection of a radio button through the up/down arrows?

I am using VB .NET. I want to know how to make the scroll-up and down arrows visible for my text boxes if the user wishes to enter more lines of text than the size of the text box can take. I would like the user to be able to scroll up and down after he/she has entered all the text.
How do I activate this property - should I be using some other control other than a text box for this?

I have a fairly simple VScrollbar problem: the Scroll event triggers when ANY arrow key is pushed, including left and right... I need it to trigger only when up/down arrow keys are pushed (which, I hope, is the default behaviour).
Essentially all I do is declare a VScroll As System.Windows.Form.VScrollBar and later I have a Private Sub VScrollBar_Scroll (...) Handles VScroll.Scroll that manages the event.
I noticed also that the left/right arrow scrolling is by a smaller increment than the up/down scrolling. All of this seems to happen in a very "black box" kind of way, I can't find any way of determining what should trigger the scroll event.
