how can i visible cadre around my buttons in c# forms. that whenever I click on it or it runs the cadr will be visible around it?
please get me the code example
private void button6_Click(object sender, EventArgs e)
{
}
If you mean the dotted line, that shows where the focus is, there is nothing you need to do; tab to the button (during runtime!) and it will show.
If you mean the change in appearence during the click, this also happens by itself.
If you want any other changes during the click, set and reset them during the MouseDown and MouseUp events, not the Click, as this will be too late.
If you are looking for still something else, please specify more precisely.
I assume you want to change the border appearance of button. Use the Button.FlatAppearance to change the border styles. But this will work only when the style is Flat.
Sample code:
button1.FlatStyle = FlatStyle.Flat;
button1.FlatAppearance.BorderSize = 2;
button1.FlatAppearance.BorderColor = Color.Red;

My combobox allows typing into the text portion so the only way to get the dropdown list is to click the button. However, since this will be used on touchscreen devices, it is hard to click it when it is this 'thin'.
Is there any way to increase the width of the combobox button?
One alternative to resizing the button would be to set the DroppedDown property to true inside the Click event. This will show the drop down list when the user clicks inside the edit area of the ComboBox, effectively extending the button area to the whole control:
private void comboBox1_Click(object sender, EventArgs e)
{
comboBox1.DroppedDown = true;
}
If you want to customize dropdown button (the size of the arrow and the size of the button are completely in our control), there is a class called ComboBoxRenderer.
Here you have complete example.
https://learn.microsoft.com/en-us/dotnet/api/system.windows.forms.comboboxrenderer?view=netframework-4.7.2
It is supported from .Net2.0.
You should create a custom ComboBox control and call DrawDropDownButton of the comboboxrenderer in the paint event.
In the above link(example) arrowSize and arrowRectangle are two variables which helps in deciding your dropdown button size, along with below static function (of ComboBoxRenderer) call in overridden paint event.
ComboBoxRenderer.DrawDropDownButton(e.Graphics, arrowRectangle,arrowState);
When I usually work with checkboxes, I check to see if the box is checked with the code below:
if (checkBox1.Checked)
{
Label1.BackColor = Color.Red;
}
This code is usually attached to a button that sets into motion when it's clicked by the user. This time, however, I want to do something, like change the color of a label, the very SECOND the checkbox is checked by the user. That is, I don't want to wait until the user pushes some other button to check if the checkbox is checked in order for the label's color to change.
How do I do this?
Sounds like you need a CheckedChanged event handler. That one's for ASP.Net, but there's a version for winforms as well (and xaml, and so on.)
Then you have to write code inside CheckedChanged Event of checkBox as below:
private void checkBox1_CheckedChanged(object sender, EventArgs e)
{
if (checkBox1.Checked)
label1.ForeColor = Color.Red;
}
Why don't you hook up to the CheckChanged event and implement your ideas there?
I have a WindowsForm that contains a lot of UserControl.
Each UserControl has a PictureBox, a few TextBox and a Button.
As soon as my program loads, my first TextBox is Highlighted in blue and I don't want that.
In fact I don't want anything to be selected at all.(Buttons, TextBox etc..)
I've looked into the properties but I can't find exactly how to totally remove this 'Feature'.
All my TextBox are ReadOnly but can become Write/Read while the program is running.
Any Idea how i could do this ?
Thanks in advance.
Update
Changing the TabStop properties to false did part of the job since it doesn't allow selection with tab at all. But I don't want to block the user from using tab to navigate between boxes I just don't want any selection when I run the program. Is there another way ?
Thanks for your time again.
On form Load set Focus to any label or any other control which is not tab stop on the form
private void Form1_Load(object sender, EventArgs e)
{
this.ActiveControl = label1;
}
How to remove the focus from a TextBox in WinForms?
You need to set TabFocus to false for textboxes etc
//textBox1.TabFocus = false;
textBox1.TabStop = false;
comboBoxName.SelectedIndex = -1;
How would I make two buttons appear the same when one is hovered over?
Picture of the buttons I want to be shown are here:

How would I make the button with the green image in the center appear as the same style (colors, borders, etc...) when the Sign On one has been hovered over / clicked?
I'm using Windows Forms.
This can be done using event handlers on mouse over/out, but frankly the right choice is to make a usercontrol containing both buttons and use that instead of the two...
Simply add handler for MouseEnter event on your "sign on" button - all you have to do in this very handler then, is changing second button's styles (implementing MouseLeave might be useful too - to revert second button to it's original style).
Code sample:
this.ButtonSignOn.MouseEnter += this.ChangeOtherButton;
this.ButtonSingOn.MouseLeave += this.RevertOtherButtonChanges;
// later on
private void ChangeOtherButton(object sender, EventArgs e)
{
this.OtherButton.ForeColor = Colors.Red;
this.OtherButton.BackColor = Color.Blue;
// more styling ...
}
// mostly same stuff when reverting changes
You could refactor those 2 handlers into one, and simply passing colors, fonts and other styles as you go... but this should be enough anyways.
I am working on winform project. At runtime when I am moving through different controls through tab key ; after one button my tab disappears for 2 clicks. I tried all things to fix this. I set tabstop=false for all contols in winform but still I am getting same problem.
Then I decided to add following code:
Control nextControl = this.GetNextControl(this.guipnlReportPatientMeasurementDetails.Controls[10], true);
where GetNextControl property gets the name of the control where my control will go after pressing tab key and Controls[10] is the button. So where should I place above piece of code so that I would get the name of next control. Should it be in button_click event or somewhere else ?
Guys please suggest.
You should set TabIndex property for each control according to the Tab order you want to impose (you can set it through designer).
Set TabStop = false only for those controls you want to exclude from Tab selection.
There's also a useful button that shows TabIndexes on the form:
You are digging yourself a hole. Find out what the real problem is, there's some kind of control that is either off the window or doesn't properly indicate the focus. If you have no clue what control that might be then add a timer and a label. Set the timer's Enabled property to True, Interval to 200. Write the Tick event like this:
private void timer1_Tick(object sender, EventArgs e) {
if (this.ActiveControl == null) label1.Text = "No control?";
else label1.Text = this.ActiveControl.Name;
}
That tells you where the tab goes.
I would first try to fix the tab order on the window before resolving to using this code. Did you do that?
