hi phabion,

you can simply split the value in your text box by using space as a splitter

Then u can remove each value in each loop. see below sample:

C#

private void button1_Click(object sender, EventArgs e)
{
    string sValue = textBox1.Text;
    string[] arrValues = sValue.Split(new char[] { ' ' });
    for (int i = 0; i < arrValues.Length; i++)
    {
        arrValues[i] = arrValues[i].ToString().Replace(arrValues[i].ToString(), "");
    }
    for (int o = 0; o < arrValues.Length; o++)
    {
        textBox1.Text = arrValues[o].ToString();
    }
}

Thanks
Chageie

Why one by one?

Which end of the string should deletion start from?

You have experience in Borlands' products so how would you have done it there? Write out the steps you would have taken, in pseudo code, and then
try to implement them in C#. When/if you get stuck ask again showing your code and asking specific questions.

Hi phabion,

What is your requirement of removing the words one by one? Is there any specific reason? Can you please elaborate it? Because, it will be easier and more user friendly if you remove the whole bunch of text from your TextBox at a time.

If you still want to remove the words one by one, first write the algorithm in a piece of paper and try to implement it in your code.

If you face any issue for a piece of code, don't hesitate to post it here. Thank you for posting it at CodeProject.

Hi Phabion,

For this you have to set radio buttons autopostback property to 'true'

and register its oncheckedchanged event.

protected void rbtn_CheckedChanged(object sender, EventArgs e)
   {
       if (rbtn.Checked)
       {
           rbtn.Checked = false;
       }
       else
       {
           rbtn.Checked = true;
       }
       if(txtText.Text.Contains(" "))
       {
           txtText.Text = txtText.Text.Substring(0, txtText.Text.LastIndexOf(" "));
       }
       else
       {
           txtText.Text = "";
       }
   }
