I am trying to assign button controls text dynamically by using a loop like the following:
int ButtonNumber = 1;
while (ButtonNumber < 10)
{
//WHAT TO DO HERE!?
ButtonNumber++;
}
I wanna avoid the following:
button1.Text = "";
button2.Text = "";
button3.Text = "";
button4.Text = "";
button5.Text = "";
button6.Text = "";
button7.Text = "";
button8.Text = "";
button9.Text = "";
Ideally, don't have button1, button2 etc as variables in the first place. Have a collection (e.g. a List<Button>):
private List<Button> buttons = new List<Button>();
(EDIT: You'd need to populate this somewhere, of course...)
then to update the text later:
for (int i = 0; i < buttons.Count; i++)
{
buttons[i].Text = "I'm button " + i;
}
This doesn't play terribly nicely with the designer, unfortunately.
You can fetch a control by ID, but personally I try not to do that. If you really want to:
for (int i = 1; i <= 10; i++)
{
Control control = Controls["button" + i];
control.Text = "I'm button " + i;
}
Create an array of buttons:
Button[] buttons = new Button[10];
for(int i = 1; i < 10; i++)
{
buttons[i] = new Button();
buttons[i].Text = "";
}
You can always use this.Controls.Find() to locate a named control in WinForms.
You can also do like this simply, assuming if you have all buttons in your form
foreach (Control c in this.Controls)
{
if (c is Button)
{
c.Text = "MyButton" + (c.TabIndex + 1);
}
}
// try this
Button btn;
for (int n_i = 0; n_i < 10; n_i++)
{
btn = (Button)Controls.Find("button" + n_i,true)[0];
btn.Text = "";
}
