Combobox variable - DucaRii - Dec 11, 2016

So, my problem is that I want to get the selected item on the combobox as string and use it in another method. Is that possible ? And how?

Maybe using Text property?

PHP Code

<?php 
if (combo.Text == "Windows")
{
    // do something when select item is "Windows"
}
else
{
    // do something when not "Windows" selected
} 

Side note: switch can be also used

Ayyy thank you bro. Could you also tell me how to send the string "value" to, for example, the main function

You are welcome

You are welcome

Code
void mainfunction()
{
    comboBox1.SelectedItem.ToString(frt);
    Console.WriteLine("bla bla {0}",frt);
}

Would this work ?

how about instead of an if statement..

Code
if (combo.Text == "Windows")

you should switch it up :)

Code
switch(combo.Text.ToLower())
{
case "windows":
...
...

it scales better :)

The method:
PHP Code

<?php 
public void CallMethod(string comboBoxSelection)
{
      // insert code
      var doSomethingWithString = comboBoxSelection;
} 

Calls the method:
PHP Code

<?php 
CallMethod(comboBox1.SelectedItem.ToString());

You obviously dont even know the basics of programming so I suggest you learn those first.

Meh, replace the two function lines with this:

PHP Code

<?php 
string Selected = comboBox1.SelectedItem.ToString();
Console.Writeline(Selected);

PHP Code

<?php 
internal class OpeartingSystem
{
    internal int Id { get; set; }
    internal string Name { get; set; }

    public override string ToString()
    {
        return Name;
    }
} 
Id should be unique
PHP Code

<?php 
internal void InitializeDataSource()
        {
            var dataSource = new List<OpeartingSystem>
            {
                new OpeartingSystem
                {
                    Id = 1,
                    Name = "Windows"
                },
                new OpeartingSystem
                {
                    Id = 2,
                    Name = "Linux"
                },
                new OpeartingSystem
                {
                    Id = 3,
                    Name = "OSX"
                }
            };
            ListOperatingSystems.DataSource = dataSource;
        } 

PHP Code

<?php 
private void ListOperatingSystems_SelectedValueChanged(object sender, EventArgs e)
        {
            var opeartingSystem = ListOperatingSystems.SelectedValue as OpeartingSystem;
            if (opeartingSystem == null) return;
            switch (opeartingSystem.Id)
            {
                case 1: //Windows
                         SomeFunction(operatingSystem.Name);
                    break;
                case 2: //Linux
                         SomeFunction(operatingSystem.Name);
                    break;
                case 3: //OSX
                         SomeFunction(operatingSystem.Name);
                    break;
                default://
                    break;
            }
        } 

I think the code is pretty self explaintory if not let me know and I can explain it.

Lol and I'm high fuh cause I didn't read he want's the string to use in another method.

Can still do that by calling the .Name lol added that in .
