Hi,

I create a text box and button dynamically in C# .net windows application by using following code.

private void lblNewUser_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
       {
           //UserName
           Label lblUN = new Label();
           lblUN.Text = "UserName";
           lblUN.Font = new Font(lblUN.Font, lblUN.Font.Style | FontStyle.Bold);
           lblUN.BackColor = Color.Transparent;
           lblUN.ForeColor = Color.White;
           lblUN.AutoSize=true;
           lblUN.Location = new Point(30,300);
           this.Controls.Add(lblUN);
           //Password
           Label lblPWD = new Label();
           lblPWD.Text = "Password";
           lblPWD.Font = new Font(lblPWD.Font,lblPWD.Font.Style|FontStyle.Bold);
           lblPWD.BackColor = Color.Transparent;
           lblPWD.ForeColor = Color.White;
           lblPWD.AutoSize = true;
           lblPWD.Location = new Point(30,350);
           this.Controls.Add(lblPWD);
           // Save Button
           Button btnSAVE = new Button();
           btnSAVE.Text="Save";
           btnSAVE.Font = new Font(btnSAVE.Font,btnSAVE.Font.Style|FontStyle.Bold);
           btnSAVE.Size = new Size(50,25);
           btnSAVE.BackColor = Color.Blue;
           btnSAVE.ForeColor = Color.White;
           btnSAVE.Location = new Point(100, 450);
           this.Controls.Add(btnSAVE);
        }

Now when I press this Save button,I want to store the value which is entered in that text box into database. Kindly send me answer.Where shouid I use the following codes.

C#

btnobj1.Click+=new System.EventHandler(ButtonClickHandler);

private void ButtonClickHandler(object sender, EventArgs e) {

where do you want to store the number? do you want it displayed somewhere or saved into a database?

Move the text box declaration line to the class level. Then you will be able to access it from anywhere in the class.

I create a text box and button dynamically in C# .net windows application by using following code.

Collapse | Copy Code

private void lblNewUser_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
//UserName
Label lblUN = new Label();
lblUN.Text = "UserName";
lblUN.Font = new Font(lblUN.Font, lblUN.Font.Style | FontStyle.Bold);
lblUN.BackColor = Color.Transparent;
lblUN.ForeColor = Color.White;
lblUN.AutoSize=true;
lblUN.Location = new Point(30,300);
this.Controls.Add(lblUN);
//Password
Label lblPWD = new Label();
lblPWD.Text = "Password";
lblPWD.Font = new Font(lblPWD.Font,lblPWD.Font.Style|FontStyle.Bold);
lblPWD.BackColor = Color.Transparent;
lblPWD.ForeColor = Color.White;
lblPWD.AutoSize = true;
lblPWD.Location = new Point(30,350);
this.Controls.Add(lblPWD);
// Save Button
Button btnSAVE = new Button();
btnSAVE.Text="Save";
btnSAVE.Font = new Font(btnSAVE.Font,btnSAVE.Font.Style|FontStyle.Bold);
btnSAVE.Size = new Size(50,25);
btnSAVE.BackColor = Color.Blue;
btnSAVE.ForeColor = Color.White;
btnSAVE.Location = new Point(100, 450);
this.Controls.Add(btnSAVE);

Solution 3

you need to create the eventhandler for the button OnClick event.

btnobj1.Click += new EventHandler(btnobj1_Click);

and you should have the method

private void btnobj1_Click(Object sender, EventArgs e)
{
// here you can play with the txtobj3.Text
}
