Let's say I've 5 texboxes:
textbox1
textbox2
textbox3
textbox4
textbox5
I want to write something in each. Is there a way to do that with a loop? I am thinking about something that looks like:
for (int i = 1; i < 6; i++)
{
textbox[i].Text = i.ToString();
}
So I'd get a number in each textbox. Or is there a way of having an array of textboxes?
Consider using this.Controls.OfType<TextBox>, which will give you a list with all the TextBoxes on your form.
You could also access them by name with this.Controls["textbox" + i]. (http://msdn.microsoft.com/en-us/library/s1865435.aspx)
List<Textbox> list = new List<Textbox>() {textbox1, textbox2, textbox3, textbox4, textbox5};
int i = 1;
foreach (var item in list)
{
item.Text = i.ToString();
i++;
}
If these 5 textboxes is your all textboxes in this form, you can use also;
int i = 1;
foreach(var item in this.Controls.OfType<TextBox>())
{
item.Text = i.ToString();
i++;
}
List<Textbox> instead of List<string>.Verious options:
this.Controls.OfType<TextBox> as csharpler said.The static option:
Create a static array:
TextBox[] textboxes = new[] { textbox1, textbox2, textbox3, textbox4, ... };
for (int i=0; i < textBoxes.Length; i++)
textboxes[i].text = (i + 1).toString();
The dynamic option:
static public SetTextBoxIndex(ControlCollection controls, ref int index)
{
foreach(Control c in controls)
{
TextBox textbox = c as TextBox;
if (textbox != null)
textbox.Text =(++index).ToString();
else
SetTextBoxIndex(c.Controls, ref index);
}
}
// Somewhere on your form:
int index = 0;
SetTextBoxIndex(this.Controls, ref index);
Create an array of Text Boxes of required size and textbox refernces to it. in your case.
TextBox[] textBoxes = new TextBox[5];
textboxes[0] = textbox1;
textboxes[1] = textbox2;
textboxes[2] = textbox3;
textboxes[3] = textbox4;
textboxes[4] = textbox5;
for (int i = 1; i < 6; i++)
{
textbox[i].Text = i.ToString();
}
Hope this will help.
