How do I access dynamically created textboxes and save their values(text) into a file?
Mar 22 2010 5:57 AM
Hello,
Could you please suggest me how I can save the contents of these dynamically created textboxes into a file? I am not able to access these dynamically created textboxes.
This is the code I've written to create text boxes.
private void button2_Click(object sender, EventArgs e)
{
int left1 = 80;
string num = textBox2.Text;
int n = Int32.Parse(num);
int b = 1;
for (int k = 1; k <=n; k++)
{
int top1 = 30, a = 0;
for (int p = 1; p <= 4; p++)
{
string str = "txt" + b + a;
TextBox txt = new TextBox();
panel1.Controls.Add(txt); //these textboxes are added on the panel
txt.Name = str;
txt.Size = new Size(30, 20);
txt.Top += top1;
top1 += 30;
txt.Left = left1;
txt.BackColor = Color.Cornsilk;
a++;
txt.Show();
}
left1 += 100;
} b++;
}
Now with a click of another button, I want to access the text I've entered in these textboxes (that are present on the panel) and save them in a file.
This is the code I've written,
private void button3_Click(object sender, EventArgs e)
{
string num = textBox2.Text;
int n = Int32.Parse(num);
string dir = textBox1.Text;
string file = "@H:\\" + dir + "
\\Test.txt
";
int a = 1, b = 1;
for (int i = 1; i <= n; i++)
{
for (int j = 1; j < 4; j++)
{
StreamWriter writer = new StreamWriter(file);
string str = "txt" + b + a;
a++;
//How can I access the [Name] of those textbox I've created dynamically on the panel????
//I want to retrieve the text of these textboxes and save it in a file
string data = str.Text;
//Error
string delm1 = "-";
writer.Write(data);
writer.Write(delm1);
writer.Close();
}
b++;
string delim2 = "$";
StreamWriter writer1 = new StreamWriter(file);
writer1.Write(delim2);
writer1.Close();
}
Could you please suggest an effective code?
Thank you in advance.
