How to check same values on gridview?

Question

I wanted to check before adding in the gridview if there are same values on the temporary gridview. and if there are atleast one same value it will stop the reading of for loop.

example :
textbox: 4
Column
2
3
4
[4]*stills add the value

in the first column. it will say "There has been same data on the list."
but stills enter the data "4" after 4 because it is not the same with 3 and 2.

VB

If grv_temporary.Rows(i).Cells(6).Text = TextBox1.Text Then
   msgbox(There has been same data on the list.")
Exit For
'do not continue process
Else
'add value

Thanks in advance guys. I know this is simple but i cannot get it.

You could use the exit for if the condition is satisfied. Sorry for my last comment I misunderstood the code for c#.

Try to trim the values and check.

What do you mean by trim the values?

You have these values in list and you have bind list with datagirdview?

i have the values inputted by the user. and bind it on gridview.

You are getting value from user and directly inserting in grid?

C#

boolean found = false;

foreach (DataGridViewRow row in grv_temporary)
{
    if (grv_temporary.Rows(i).Cells(6).Value == TextBox1.Text)
    {
        // row exists
        found = true;
        MessageBox.Show("Row already exists");
        break;
    }
}

if (!found)
{
    grv_temporary.Rows.Add(TextBox1.Text); // Your values here.
}

Try this. Read here[^] And Grid View add quantity if data already exists..[^]
