I am currently working with an API for a program called Rhinoceros. The program does not allow tabbing through Forms so I am trying to program it in. It works well how I have it, however, when I try to tab from a combobox to a textbox or vice versa the cursor doesn't move. I have tried the select() and focus() function, neither seem to work and I am currently trying SelectNextControl but I cannot seem to get it to work either. If you have any ideas please let me know, anything is helpful.
private void cbNPProjectFolder_KeyDown(object sender, KeyEventArgs e)
{
if(e.KeyData == Keys.Tab)
{
txtbxNPProjectNum.SelectNextControl(sender as Control, true, false, true, true);
e.Handled = true;
e.SuppressKeyPress = true;
}
}
I ended up figuring it out, If anyone else has this problem:
I selected all of the containers I wanted to tab through, went to events on the bottom right, in the KeyDown box I named it Generic_KeyDown.
private void Generic_KeyDown(object sender, KeyEventArgs e)
{
if(e.KeyCode == Keys.Tab)
{
e.Handled = true;
this.SelectNextControl((Control)sender, true, true, true, true);
e.SuppressKeyPress = true;
}
}

I have a Windows Form Application. I want some functions to work with the space key. But when I press the space key, the function I want is not working and it goes to the next form. (I did KeyPreview = true)
private void Form7_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Space)
{
IEyeTracker eyeTracker = EyeTrackingOperations.FindAllEyeTrackers().FirstOrDefault();
GazeDataStop(eyeTracker);
}
}
Because:
1- If you have buttons, ... keydown won't work as form won't have focus anymore
2-you must handle the keydown so that it is not passed to ohter controls
Solution for 1:
set KeyPreview property of your form to true
Solution for 2:
set e.Handled = true:
private void Form7_KeyDown(object sender, KeyEventArgs e)
{
e.Handled = true;
if (e.KeyCode == Keys.Space)
{
IEyeTracker eyeTracker = EyeTrackingOperations.FindAllEyeTrackers().FirstOrDefault();
GazeDataStop(eyeTracker);
}
}
I cant figure out how to disable whitespaces, I tried multiple things, and yes my mask is 00000000000 but still it allows whitespaces. Anyone know a fix?
Not much code to show, only:
Should only allow numbers to be entered, not whitespaces too :/
Add the KeyDown Event to your textbox and then add the following Code in the created method:
private void textBox_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Space)
{
e.Handled = true;
e.SuppressKeyPress = true;
return;
}
}
I've got multiple text and combo boxes in my Visual Studio 2012 project, and I have the keydown set to execute different events on Enter being pressed. And, there's that useless, stupidly annoying beep, every time. I've looked all over, found e.Handled = true and e.SuppressKeyPress = true solutions, and they're doing not a damn thing.
The code from one of my combobox is:
private void cmbNavigate_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
e.SuppressKeyPress = true;
webBrowser1.Navigate(cmbNavigate.Text);
}
}
I've tried with the Suppress and the standard Handled and neither works, it just keeps beeping away mockingly at me.
Try e.Handled = true; in addition to e.SuppressKeyPress = true;
I Googled around but seems my problem happens when two gropboxes are overlapping, in my case they are not overlapping!
Problem is that the Visible property of groupbox doesn't work. what am I trying to do is that groupbox1 is visible when program starts and groupbox2 is not, by clicking on a button it should goes invisible and groupbox2 should appear, clicking the same button this action should be done vice versa.
here is my code:
private void button2_Click(object sender, EventArgs e)
{
if (groupBox2.Visible == false)
{
groupBox1.Visible = false;
groupBox2.Visible = true;
}
if (groupBox1.Visible == false)
{
groupBox1.Visible = true;
groupBox2.Visible = false;
}
}
Your problem is that after the first if-statement, it immediately checks if groupBox1.Visible is false, which it always will be. It then proceeds to flip it back.
Change the if to an else, or at least and else if and your code will work.
I have this code:
this.searchInput.KeyPress += new System.Windows.Forms.KeyPressEventHandler(this.inputKeypress);
private void Keypress(object sender, KeyPressEventArgs e)
{
// If Tab has been pressed
if(122 == (int)e.KeyChar)
{
switchTab(sTab);
MessageBox.Show(sTab);
}
}
What it does is that it sets focus to another element.
But, when the focus is set to a TextBox, and I press TAB, it just makes a tab in the TextBox, and does not set focus on the next element.
Anyone got an idea how can I make this work?
I've tried to set e.Handled = true; but that didn't work...
Have you tried setting AcceptsTab on the TextBox to false?
Edit:
yep. It does not work. Strange... It still tabulates in the textbox
That makes little sense. I ran a small test app, and the tab key only brings focus away from the TextBox when its AcceptsTab and Multiline properties are both true, regardless of an event handler being defined for KeyPress.
Are you sure some other code isn't setting AcceptsTab to true? If you are, does setting Multiline to false change the tab behaviour at all? Could you post more of your relevant code?
Set the AcceptsTab property of the text box to false?
You'll need to create an instance of the control like so, and override the following methods:
using System.Windows.Forms
//optional namespace
public class NoTabTextBox : TextBox
{
protected override bool IsInputKey(Keys keyData)
{
switch (keyData)
{
case Keys.Tab:
return true;
}
return base.IsInputKey(keyData);
}
protected override void OnKeyDown(KeyEventArgs e)
{
if (e.KeyCode == Keys.Tab) { e.Handled = true; e.SuppressKeyPress = true; }
base.OnKeyDown(e);
}
}
Build the solution, then subsitute you're regular TextBox with the new one 'NoTabTextBox', by finding it under the user controls in toolbox.
This will capture the Tab key and force it to do nothing.
