Thank you for any help :)

What I have tried:

C#

private void button_Click(object sender, KeyEventArgs e)
     {
       for (int i = 0; i < datagrid.row.Count - 1; i++)

          {

             string t = Convert.ToString(datagrid.Rows[i].Cells[3].Value);
            if (t =="research_Key")
            {
          MesssageBox.Show("ok");
             }

           }

      }

If your WPF app uses C# then there is nothing to convert.

Except, why are you converting a string to a string? Does that really make sense to you?

FYI C# in WPF is exactly the same C# that is in Winforms. You need to explain your problem better.

I've just updated my code , I wish it's more clear

And that code really makes no sense. At the end of that loop the variable t contains the same string as the last row in the datagrid.

Worse t does not exist outside of the loop and appears to have nothing to do in the loop.

t could be the string from any row in data grid ; I've just updated my code , I wish it's more clear

Does it make any sense to use unbound DatagridView with or without WPF.
Please read about MVVM and Bindings

I believe it is not datagrid.row.Count -> datagrid.Rows.Count

WPF DataGrid does not have the Rows property, and there is nothing to indicate whether the grid is bound or not.

It's a For loop to test datagrid rows cells ,
my code works in Windows forms App c# , But I'm beginner in wpf that's why I'm having some difficulties. Thank you .

Solution 1

As you have discovered, the WPF DataGrid does not have a Rows property

Try something like this:

C#

foreach (System.Data.DataRowView dr in datagrid.ItemsSource)
{
    string t = dr[3].ToString();
    if (t =="research_Key")
    {
        MesssageBox.Show("ok");
    }
}

But as @Richard-MacCutchan pointed out - t will only be the string from the last row in the DataGrid
