i have 5 textboxes and a richtextbx of 5 line. how can i get 1st line text of richtextbox in 1st textbox, 2nd line text of richtextbox in 2nd textbox, and so on.

C#

private void myRichTextBox_Click(object sender, EventArgs e)
        {
            string[] lines = richTextBox1.Lines;
            if (lines.Length >= 5)
            {
                myTextBoxForLineOne.Text = lines[0];
                myTextBoxForLineTwo.Text = lines[1];
                myTextBoxForLineThree.Text = lines[2];
                myTextBoxForLineFour.Text = lines[3];
                myTextBoxForLineFive.Text = lines[4];
            }
        }

suppose if we left myTextBoxForLineTwo blank then it shows blank space in myRichTextBox.
how to remove this blank space from myRichTextBox.

There are quite a lot of ways to do that - the most obvious is:

C#

List<string> nonBlankLines = new List<string>();
foreach (string s in lines)
   {
   if (!string.IsNullOrWhiteSpace(s)) nonBlankLines.Add(s);
   }

But you could use any of half a dozen other methods.

hi,

try this code...,

create control array in coding for your 5 textboxes.

declare textbox control array in class.
private TextBox[] textBoxes;

and follow the below code..

C#

string[] lines = richTextBox1.Lines;
textBoxes = new TextBox[] { myTextBoxForLineOne, myTextBoxForLineTwo, myTextBoxForLineThree, myTextBoxForLineFour, myTextBoxForLineFive};
int txtboxCnt = 0;

if (lines.Length >= 5)
{
    for  (int i=0; i< lines.Length; i++)
    {
        if (lines[i].Trim() != "")
        {
            textBoxes[txtboxCnt].Text = lines[i];
            txtboxCnt++;
        }
    }
}
