give copy access to the text of a label in a window - c#

I am developing a application using C#.
I have a window which has a label containing some text.
I want to copy as we copy something from anywhere.
But i cant copy of the label from the window.
How can i do that to copy the text of the label???

You will not be able to do this with a label.
You could try doing this with a textbox, to simulate the label and hightlight select.
TextBox.ReadOnly Property
Use the ReadOnly property to specify whether the contents of the
TextBox control can be changed. Setting this property to true will
prevent users from entering a value or changing the existing value.
and something like
TextBox1.Text = "Hello, Select Me";
TextBox1.ReadOnly = true;
TextBox1.BorderStyle = 0;
TextBox1.BackColor = this.BackColor;
TextBox1.TabStop = false;

Add a method to the label to make the label get focus if clicked:
private void label1_Click(object sender, EventArgs e)
{
label1.Focus();
}
Set the 'KeyPreview' property of the form to 'true' so it will process keys being pressed. I also added a method to handle the keydown event:
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
if (label1.ContainsFocus && e.Control && e.KeyCode == Keys.C)
Clipboard.SetText(label1.Text);
}
This should work even if the "KeyPreview" property is false. This property is true if the form will receive all key events; false if the currently selected control on the form receives key events. The default is false

By default winforms label control doesn't support the feature of selecting text and copying. Instead you can add click event to the label and onclick give focus to the label. And in the form key press event check if label is focused and Ctrl+C is clicked then copy it to click board.
private void label1_Click(object sender, EventArgs e)
{
label1.Focus();
}
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
if (label1.ContainsFocus && e.Control && e.KeyCode == Keys.C)
Clipboard.SetText(label1.Text);
}

Selection of all of the content of TextBox is not working as expected in WPF

Im having troubles with Selecting All content inside of a TextBox.
Ussually by pressing enter I'm jumping from one textbox to another, because there are like 6-7 TextBoxes below each other
in my Grid, and by pressing enter I need to jump from one to another,
private void Grid_PreviewKeyDown_1(object sender, KeyEventArgs e)
{
if (e.Key == Key.Enter)
{
UIElement element = e.Source as UIElement;
element.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));
//TextBox tb = (sender as TextBox);
//if (tb != null)
//{
// tb.SelectAll();
//}
}
}
And while I'm on some of them when I press Enter I'm doing some calculation like this:
private void txt2_PreviewKeyDown(object sender, KeyEventArgs e)
{
if (e.Key == Key.Return)
{
try
{
CalculateSomethingFromOtherTextBoxes();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
}
My Question is next: When I jump from each other and when I finish calculation (enter is pressed), the next TextBox I will jump to I would like SELECTALL of TextBox's content when I jumped on it.
In case I want to edit some value or whatever, and it is confusing sometimes content insidee is selected and sometimes it is not.
I tried setting GotFocus event on each of TextBoxes and It looks like this:
private void txt3_GotFocus(object sender, RoutedEventArgs e)
{
txt3.SelectAll();
}
But unfortunately somehow this is sometimes working sometimes it is not, I mean all of content is selected sometimes and sometimes it is not..
Thanks guys
Cheers
Try to handle the GotKeyboardFocus event instead of the GotFocus event. This should work:
private void txt3_GotKeyboardFocus(object sender, KeyboardFocusChangedEventArgs e)
{
txt3.SelectAll();
}
There is no property that you can set to select all of the Text in a TextBlock or TextBox. Selecting all text must be accomplished using the TextBoxBase.SelectAll Method. What you could do in a Style is to set an event handler for the GotFocus event, where the handler code would call SelectAll, but your handler would of course need to be in code and not XAML.
One other possibility would be for you to create an Attached Property that would select the text whenever the TextBox gets focus, but again it's not possible to do this in XAML.

How to change text of Label while typing in TextBox

Please I'm new to C#, I created a textBox and a label. What i am expecting is, if I type a value into the textBox, I want it to display on the label and if I change the value it should also change immediately on the label.
it work with the code below and i press enter key
private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
label1.Text = textBox1.Text;
}
}
But I want it without press Enter/Return Key on keyboard.
Thanks for understanding
This works for VisualStudio
Select your TextBox in the Designer, go to the it's properties and click on the events (teh icon with the lightning). Then make a double click on the event that is called: TextChanged.
This creates a new function, that will always be called when the text of your TextBox changes. Insert following code into the function:
private void textBox1_TextChanged(object sender, EventArgs e)
{
TextBox tb = sender as TextBox;
label1.Text = tb.Text;
}
That's it.
label.DataBindings.Add("Text", textBox, "Text");
textbox KeyDown/Up/Press events may help.
For example
private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
label1.Text += e.KeyData.ToString();
}

Set label to textbox content

Here's what i want to do:
I want to be able to take the contents entered into a textbox. Once the user hits the ENTER key or the enter button I made, to have that content appear in a label I've placed on my form.
And have that same label change to whatever you enter in the textbox everytime you hit enter.
I hope I explained this good enough. Thanks!
Subscribe to KeyDown event of TextBox and check if Enter is pressed
private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
label1.Text = textBox1.Text;
}
add a button to your form, double click it, inside the event add the code below
label1.text=textbox1.text
and do some basic tutorials, dude
Assuming you are using winforms... First you need to enssure that your form will response to keyboard events.
So you need to set the property KeyPreview to true.
Then use the event KeyDown and write this code:
private void form1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
myLabelName1.Text = myTextBoxName1.Text;
}

How can I override the default button on a form when focus is in a TextBox

I have a winform form which has typical OK and Cancel buttons.
The OK button is set as the default button. When the user presses the ENTER key, the form is closed.
The form also has a text box which has a Search button beside it. The text box allows the user to enter search text and the Search button initiates the search function.
I would like the user to be able to press the ENTER key when the text box has the input focus and have the search function activate.
The problem is that the form is grabbing the ENTER key event before the text box's handler gets it.
EDIT: I've tried using the following event handlers, but they never get hit, and the form closes when the Enter key is hit:
private void txtFilter_KeyUp(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
Search();
e.Handled = true;
}
}
private void txtFilter_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
Search();
e.Handled = true;
}
}
I've also tried enabling the KeyPreview property on the form and implementing a KeyDown event handler for the form, but the Enter key never seems to cause any of these to be hit.
What is the best way to accomplish this?
Try handling the Enter and Leave events of the TextBox to clear out your form's AcceptButton property:
private void txtFilter_Enter(object sender, EventArgs e) {
this.AcceptButton = null;
}
private void txtFilter_Leave(object sender, EventArgs e) {
this.AcceptButton = closeButton;
}
Then you can just process your KeyUp event as your want:
private void txtFilter_KeyUp(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
Search();
}
}
Add a KeyDown event handler to the textBox and then add this to it
if (e.KeyCode == Keys.Enter)
{
btnSearch.PerformClick();
}

Make shortcuts appear in multiple menus

I am using a TextBox in a custom UserControl that I am creating. It seems that the default contextmenu doesn't show the shortcuts for Cut, Copy, Paste. This is fine, as long as they are just working.
But my Form using the UserControl has a MenuStrip that contains these default shortcuts as well. But the Cut, Copy, Paste commands are not working anymore, now that the shortcuts are assigned to the MenuStrip.
How can I use shortcuts at multiple positions in my forms? What is the best way to pass a global command like Cut and post it deeper into my UserControl? And is it possible to add the shortcuts to the default contextmenu of the textbox?
A MenuStrip item or ToolStrip item doesn't change the focus when it is clicked or its shortcut keystroke is pressed. Which is the ticket to implementing this functionality, the form's ActiveControl tells you which control has the focus. You just need to check if it is a TextBox. Like this:
private void copyToolStripMenuItem_Click(object sender, EventArgs e) {
var box = this.ActiveControl as TextBoxBase;
if (box != null) box.Copy();
}
Do the same for the Paste() and Cut() methods. You can further enhance the UI by selectively enabling these menu/toolbar items by subscribing to the Application.Idle event and checking if the ActiveControl is a text box and the text box or clipboard contains any text. Like this:
public Form1() {
InitializeComponent();
Application.Idle += Application_Idle;
}
protected override void OnFormClosed(FormClosedEventArgs e) {
Application.Idle -= Application_Idle;
base.OnFormClosed(e);
}
void Application_Idle(object sender, EventArgs e) {
var box = this.ActiveControl as TextBoxBase;
copyToolStripMenuItem.Enabled = box != null && box.Text.Length > 0;
cutToolStripMenuItem.Enabled = copyToolStripMenuItem.Enabled;
pasteToolStripMenuItem.Enabled = box != null && Clipboard.ContainsText();
}
You have to just enabled the property of textbox for the same and it will start responding.
Just verify that myTextBox.ShortcutsEnabled = TRUE;
