Solution 1

After the loop you could add

txtclients.Text = txtclients.Text.TrimEnd('\n');

It is still showing space in the last line ...
I have tried outside loop and inside loop as well

Actually this trim function is trimming that \n but the next is created , how to get rid of it

Get the count of items in the list, and create a counter variable that you increase in the loop so you always know which item you are processing, and put an if around the concatenation so it only adds if it's not the final item in the list, eg if (counter < storedata.Count).

Or if it's possible change your "foreach" into a "for" loop so you key the row count that way, and again put the "if" around the line you don't want to execute.

Solution 2

First, choose the language:
- the code is not basic
The principle of foreach is avoid having a counter thus, in the loop, you don't know when you are in last iteration.
The traditional solution is more like:

C#

txtclients.Text = txtclients.Text + storedata[0];
for (int i=1; i< storedata.count; i++)
{
    txtclients.Text = txtclients.Text + "\n" + storedata[i];
}

In this Case i will get a empty line on the top instead in the end
because first it will create a line and then will store the data

No, look better at my code.
first line matters too.

Solution 3

If you're replacing the entire contents of the textbox, try the simple approach:

C#

txtclients.Text = string.Join("\n", storedata);
