There is a comboBox and a button on a win form. How can I fire the comboBox selectedIndexChanged by clicking on the button.
You should rethink your code design a little. It seems you want to raise the event to trigger some action indirectly. Why not try it like this:
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
// do the things that should happen only if a real change happend
// ...
// then do the special thing you want
DoTheOtherStuff();
}
private void button1_Clicked(object sender, EventArgs e)
{
// do the things to happen when the button is clicked
// ...
// then do the special thing you want
DoTheOtherStuff();
}
private void DoTheOtherStuff()
{
// the special thing you want
}
EDIT: If your legacy code is so awkward as your comment suggests, you can still use this awkward way:
private void button1_Clicked(object sender, EventArgs e)
{
comboBox1_SelectedIndexChanged(comboBox1, EventArgs.Empty);
}

When creating a winforms application I added a pannel as a header so I could make the application borderless, I was going to add some buttons when I realised no events were getting registered by the program. Have I flicked a wrong switch somewhere?
I have already tried clicking the main form and changing the AutoValidation as well as checking that the form, as well as the panel, were both enabled.
public App()
{
InitializeComponent();
}
private void TopBar_MouseHover(object sender, EventArgs e)
{
Application.Exit();
}
private void ExitButton_Click(object sender, EventArgs e)
{
Application.Exit();
}
Expect result is that it should just close the application when I hover over the topbar or when I click the ExitButton.
I fixed this by going through the properties of the Forms/Buttons and resetting them as it turns out I had one item disabled.

I am doing a school project and i can´t figure out how to "hide" some text blocks when the toggle switch is on and the opposite? Developing a windows 8 app. Thanks and btw. How do you make a collection from multiple text blocks(XAML)?
private void ToggleSwitch_Toggled(object sender, RoutedEventArgs e)
{
}
Assuming your control structure is fairly flat, you can get by using the Tag property on the TextBox. In your XAML, put some distinct value in the Tag field for each TextBox you want to make toggle-able, like the word 'CanToggle'. Then you can do something like
private void ToggleSwitch_Toggled(object sender, RoutedEventArgs e)
{
foreach (Control currentControl in this.Children)
{
if (currentControl.Tag == "CanToggle")
currentControl.Visible = !currentControl.Visible;
}
}
If your control collection is not flat, then you'll have to figure out how to dig recursively through the collection of controls to locate all the TextBox that you want to toggle. This answer may help.

Personally, I use Ctrl+M to "collapse to defininitions" more than anything else though.

It skips the navigating to valid URL and goes straight to a Google search. If I enter "stackoverflow.com" into textbox it will Google search for "stackoverflow.com".
private void button1_Click(object sender, EventArgs e)
{
webBrowser1.Navigate(textBox1.Text); //navigates to url in textbox
if (!textBox1.Text.StartsWith("http://"))
{
webBrowser1.Navigate("http://www.google.ie/search?q=" + (textBox1.Text));
}
}
That code, in English, basically says "navigate to whatever was entered into the textbox. Then, IF whatever you entered into the textbox does NOT start with 'http://' let's immediately do a Google search for it."
Basically you are navigating to stackoverflow.com but you're then immediately Google searching for it instead. If you want it to act differently, you need to code it differently.
Here's how I'd rework it:
private void button1_Click(object sender, EventArgs e)
{
if (!textBox1.Text.StartsWith("http://"))
{
// didn't start with "http://" so search for it
webBrowser1.Navigate("http://www.google.ie/search?q=" + (textBox1.Text));
}
else
{
// navigate directly to the URL
webBrowser1.Navigate(textBox1.Text);
}
}
In an if-else statement, only one logic path will be chosen based on conditions. It will never be the case that both run.
It searches Google because your logic is saying that 'if the textbox contents doesn't start with http:// let's do a Google search'. You are actually loading stackoverflow.com, but you immediately change the page and load Google instead.
You might want the code below with your code modified to 'filter' out and save some memory by not loading stackoverflow.com first:
private void button1_Click(object sender, EventArgs e)
{
if (!textBox1.Text.StartsWith("http://") | !textBox1.Text.StartsWith("www") || !textBox1.Text.StartsWith("http://www"))
{
webBrowser1.Navigate("http://www.google.ie/search?q=" + (textBox1.Text));
}
else
{
webBrowser1.Navigate(textBox1.Text); //navigates to url in textbox
}
}

i have this project in my visual studio and i have a form which is linked to a solution in a project.
So, i need to call it on a button click.
It's like:
private void button1_Click(object sender, EventArgs e)
{
poComp.Client.StartpoComp
}
The thing is i have not copied the code the right way, houw should it proceed?
What is the file's structure?
Sorry, i know this might sound dumb and it probably is but i'm right in the beginning.
Below will do what (I think) you want to do but I strongly advise that you google "using classes c#" to try and find some tutorials
Here is just one
private void button1_Click(object sender, EventArgs e)
{
StartpoComp spc = new poComp.Client.StartpoComp();
//myFormsLabel.Text = spc.SomePublicVariable;
//spc.SomePublicMethod(param1);
}

Please can you help me how can i create popup panel with informations for mouseover. I using C# offline application.
I don't know how can i do this on mouseover with application. For website it is javascript but for C# ... i don't know.
I know how to use mouseover for it, but i don't know how to create popup window with informations for mouseover. It's exactly my problem. Please can you help me?
You could start by testing the following:
You can use MouseEnter to show a window in a popup style.
private void panel1_MouseEnter(object sender, System.EventArgs e)
{
MyForm frm = new MyForm();
frm.ShowDialog();
}
When you require behavior like jquery UI Tooltip you can use UserControl
private Control popup;
private void panel1_MouseEnter(object sender, System.EventArgs e)
{
MyUserControl mcu = new MyUserControl ();
this.popup =mcu; //save references to new control
this.Controls.Add(this.popup);
this.popup.Location.X = ((Control)sender).Location.X+ offsetX;
this.popup.Location.Y = ((Control)sender).Location.Y+ offsetY;
}
private void panel1_MouseLeave(object sender, System.EventArgs e)
{
this.Controls.Remove(this.popup);
}
This sounds suspiciously like a ToolTip.
So I recommend that you use the ToolTipService for this (in your xaml):
<object>
<ToolTipService.ToolTip>
<objectThatFillsTheToolTip .../>
</ToolTipService.ToolTip>
</object>
