How to assign values to dynamic controls in c# winform?

Hi friend,

How to give dynamic control setting values?

My codes:

Form1:

using System;

using System.Text;

using System.Windows.Forms;

namespace WindowsFormsApplication1

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

TextBox dynamicTB= new TextBox();

dynamicTB.Top = 20;

dynamicTB.Left = 20;

dynamicTB.MouseClick += new MouseEventHandler(textBox_MouseClick);

this.Controls.Add(dynamicTB);

TextBox dynamicTB2 = new TextBox();

dynamicTB2.Top = 50;

dynamicTB2.Left = 20;

dynamicTB2.MouseClick += new MouseEventHandler(textBox_MouseClick);

this.Controls.Add(dynamicTB2);

etc ...

}

private void textBox_MouseClick(object sender, MouseEventArgs e) {

Form2 f2 = new Form2();

f2.GetDateTimeValue += new Form2.GetDateTimeValueHandler(GetValueForTextBox);

f2.Show();

}

private void GetValueForTextBox(object sender, GetValueForTextBoxArgs e)

{

TextBox tb = (TextBox)sender;

tb.Text = e.VText;

// MessageBox.Show(e.VText);

// To assign to the current object(TextBox).

// In other words: Assign a value to the object that triggered the event

}

Form2:

public partial class Form2 : Form

{

public Form2()

{

InitializeComponent();

}

public delegate void GetDateTimeValueHandler(object sender, GetValueForTextBoxArgs e);

public event GetDateTimeValueHandler GetDateTimeValue;

private void button1_Click(object sender, EventArgs e)

{

GetValueForTextBoxArgs args = new GetValueForTextBoxArgs(dateTimePicker1.Value.ToString());

GetDateTimeValue(this, args);

this.Dispose();

}

public class GetValueForTextBoxArgs : System.EventArgs {

public string VText { get; set; }

public GetValueForTextBoxArgs(string text)

{

this.VText = text;

}

Thanks.

Try:

// on Form1

private void textBox_MouseClick(object sender, MouseEventArgs e)

{

TextBox tb = (TextBox)sender;

Form2 f2 = new Form2(tb);

f2.GetDateTimeValue += new Form2.GetDateTimeValueHandler(GetValueForTextBox);

f2.Show();

}

private void GetValueForTextBox(object sender, Form2.GetValueForTextBoxArgs e)

{

TextBox tb = (TextBox)sender;

tb.Text = e.VText;

MessageBox.Show(e.VText);

// To assign to the current object(TextBox).

// In other words: Assign a value to the object that triggered the event

}

// on Form2

private TextBox tb;

public Form2(TextBox tb)

{

InitializeComponent();

this.tb = tb;

}

private void button1_Click(object sender, EventArgs e)

{

GetValueForTextBoxArgs args = new GetValueForTextBoxArgs(dateTimePicker1.Value.ToString());

GetDateTimeValue(tb, args);

this.Dispose();

}
