A textBox doesnt allow a transfert coming from a form

Israel

Hi!

I need to transfer the data I have inside of my txtName to other textbox named txtBox1. Curiosly its doesnt allow textbox only label (as you can see). Why I need only textbox? Just because with the textbox where I need to put my data coming from txtName its in multiline mode. But not for a label. How can I resolv it please.

FormToPrint= new FormToPrint();

frmToPrint.label.Text = txtName .Text.ToString();

frmToPrint.Show();

Hi Israel,

As per your code you are using Constructor to pass value to other form and it should work perfectly.

If NOT please tell us what are values you are getting in form2 and also provide the error message if you have any.

Hi!

The code doesnt works properly. Look what I did to make it works:

//form1
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
string nTitle = textBox1.Text;
string nText = textBox2.Text;
Form2 frm = new Form2(nTitle,nText);
frm.Show();
}
}
//form2
public partial class Form2 : Form
{
public Form2()
{
}
public Form2(string title,string txt)
{
InitializeComponent();
this.Text = title;
label1.Text = title;
this.Text = txt;
textBox1.Text = txt;
}

In any way, Thanx trying helping me!

Hi,

As per your requirement: you want to pass values from Form1 to Form2. You can accomplish in following two ways:

Option 1(Using public variable):
Step 1: Declare a public variable in Form2

//FormTwo
public string userName;
onForm_Load()
{
TextBox1.Text = userName;
}

Step 2 : Set Form1 textbox value in public variable on button click.

FormOne_Button1_Click()
{
//create a object of formTwo
FormTwo frmtwo = new FormTwo();
//Access global veriable and assign values to it
frmtwo.userName = txtUserId.Text;
//Hide formOne
this.Hide();

//show formtwo
frmTwo.Show();
}

Option 2(Using constructor):

Create Form2 object and pass the textbox value in Form1 and in Form2 declare a parameterised constructor to receive the value.

Form1:
//FormOne FormTwo
FormTwo frmtwo = new FormTwo(txtUserId.Text);
frmTwo.Show();

Form2:
//FormTwopublic
string username;

// In formtwo Constructor assign a value to it's veriable
FormTwo (string username)
{
Init()
this.username= username
}

onForm_Load()
{
TextBox1.Text = usename;
}

Another way also there by declaring static variable. You need to declare static variable in Form1 and on button click you need assign the textbox value to static variable. Then in Form2 you can find the value like Form1.staticVal

But this option is not good as compared to above two options because static values are stores in memory always.

In order to resolve your problem you need to choose either Option1 or Option2.

Hope this will resolve your problem.

Hi,

can you please tell me how you want to pass value from form1 to form2 means when you click on button or other

ai, ai, ai, its doesnt works! Let me explain it well before to repost my code.

1. I have two forms (from1 and form2) .
2. On form1, I have a textBox1 with a label (where I should click)
3. On from2 I have another textbox1 (its on this textbox where its should receive the value coming from the textbox1 of form1).
4. then what happen? on form2 I put the textBox1 I change the Modifiers' properties as Public
5. the textBox1 of the form2 it's in Multiline mode
6. now these the whole code:

private void labelPreview_Click(object sender, EventArgs e)
{
FormToPrint= new FormToPrint();
frmToPrint.textbox1.Text = txtName .Text.ToString();
frmToPrint.Show();

7. curiosly when I do this its works. I means when I use a label its works (not for a textbox):
FormToPrint= new FormToPrint();
frmToPrint.Label1.Text = txtName .Text.ToString();
frmToPrint.Show();

Hi Israel,

There are so many methods to pass data between forms in Windows application. In that some of the ways are
Using constructor
Using objects
Using properties
Using delegates
Here i am using Constructor Approach
Create a constructor with one parameter in FormToPrint

public FormToPrint(string str)
{
   InitializeComponent();
   txtBox1.Text = str;
}

In form1 pass the value of the textbox to the parameterized constructor of FormToPrint form

private void lblVisualizar4_Click(object sender, EventArgs e)
{
   FormToPrint frmToPrint = new FormToPrint (txtName.Text);
   frmToPrint.Show();
}

Then, I have two forms where I am passing values between, The next form that receive the value is FormToPrint.
The problem is its works when on the next form (FormToPrint) there is a label that will receive.
But I replace to a textbox. Its doesnt recognize... Means its doesnt give the case sensitive to show me in list the textbox I do put on the next (or segond form).
I do know if I am clear. Please let me know if its clear now or not.

I need to change this frmToPrint.label.Text to this frmToPrint.textbox.Text

private void lblVisualizar4_Click(object sender, EventArgs e)
{
FormToPrint frmToPrint = new FormToPrint ();

frmToPrint.label.Text = txtName .Text.ToString();
frmToPrint.Show();
}

Your question is not clear to me. Please put your code what you have attempted or explain clearly.
