Thanks for the reply Karthik.
Your mentioned scenario what is happening is "abc" is getting displayed on to the text box. But what i need is what ever i write on text box, model property should be updated when i call some ok button.

you want to use same model ?
private void btn_Click(object sender, EventArgs e)
{
Model objModel = new Model();
objModel.UserName = txtUserName.Text;
}

Yes.
I dont want to use it directly like objModel.UserName = txtUserName.Text;
I want to use with binding only.

Model objModel = new Model();
private void Form1_Load(object sender, EventArgs e)
{

objModel.UserName = "Abc";
txtUserName.DataBindings.Add("Text", objModel, "UserName");
}

private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show(objModel.UserName);
}
