windows Apllication: How to bind dynamically multiple controls like textbox,radionbutton,list, checkbox and etc. and also events dynamicall., with neat alighnment.

here a example of simple calculator uses dynamically

        Button[] bntArray = new Button[10];
        Button[] btnSign = new Button[5];
        string[] signArry = new string[] { "+", "-", "*", "/", "=" };

  private void Form1_Load(object sender, EventArgs e)
        {
            for (int i = 0; i < 10; i++)
            {
                bntArray[i] = new Button();
                bntArray[i].Width = 50;
                bntArray[i].Height = 30;
                bntArray[i].Text = i.ToString();
                bntArray[i].BackColor = Color.Transparent;
                flowLayoutPanel1.Controls.Add(bntArray[i]);
                bntArray[i].Click += new EventHandler(ButtonClick1);
            }
            for (int j = 0; j < 5; j++)
            {
                btnSign[j] = new Button();
                btnSign[j].Width = 50;
                btnSign[j].Height = 30;

                if (j < 4)
                {
                    btnSign[j].Click += new EventHandler(SignClick);
                }
                else
                {
                    btnSign[j].Click += new EventHandler(EqualClick);
                }
                btnSign[j].Text = signArry[j].ToString();
                btnSign[j].BackColor = Color.Transparent;
                flowLayoutPanel2.Controls.Add(btnSign[j]);
            }

        }


private void SignClick(object sender, EventArgs e)
        {
            Button bt = (Button)sender;
            sign = bt.Text;
            FirstNo = decimal.Parse(textBox1.Text);
            textBox1.Clear();
        }

        void EqualClick(object sender, EventArgs e)
        {
            decimal secondNo = Convert.ToDecimal(textBox1.Text);
            decimal Result = 0;
            if (sign == "+")
                Result = FirstNo + secondNo;
            else if (sign == "-")
                Result = FirstNo - secondNo;
            else if (sign == "*")
                Result = FirstNo * secondNo;
            else if (sign == "/")
                Result = FirstNo / secondNo;

            textBox1.Text = Result.ToString("0.0000");
        }

        void ButtonClick1(object sender, EventArgs e)
        {
            Button btn = (Button)sender;
            textBox1.Text += btn.Text;
        }

I don't understand what you mean by dynamic binding. You want to add dynamic controls at runtime based on some conditions. You can use swicth case with my comments below like this --

switch(val)
{
        case 1:
                TextBox tb = new TextBox();
                tb.TextChanged += new EventHandler(tb_TextChanged);
                tb.Location = new Point(100, 100);
                this.Controls.Add(tb);
                break;
        case 2:
                CheckBox cb = new CheckBox();
                cb.CheckedChanged += new EventHandler(cb_CheckedChanged);
                cb.Location = new Point(110, 110);
                this.Controls.Add(cb);
                break;
        default:
                break;
}

Hello Nitesh,

I want to bind controls dynamically in windows form..

like is anything possible to use case statement in windows..

I will bind controls and ID's dynamically.

like for Example:

Textbox=1
checkboxlist=2

I will get the values from dataset as ID=1 and IDname=xxx; then ID=1 and IDbname=YYY

I want to bind like this according to the number of controls

You can add a control and create events at runtime like this -

private void button1_Click(object sender, EventArgs e)
{
        TextBox tb = new TextBox();
        tb.TextChanged += new EventHandler(tb_TextChanged);
        tb.Location = new Point(100, 100);
        this.Controls.Add(tb);
}

void tb_TextChanged(object sender, EventArgs e)
{
        throw new NotImplementedException();
}

Note that, I have added a textbox and its TextChanged event handler at the click of a button.
