This code should work:

for (int i = datagrid.Items.Count-1; i >= 0; i--)
{
    var cellValue = datagrid.Columns[0].GetCellContent(datagrid.Items[i]) as TextBlock;
    string cellValue2 = cellValue.Text;
    if (cellValue2 == textbox.Text) // check the search_string is present in the row of ColumnName
    {
        //For the case you set an ItemsSource:
        (datagrid.ItemsSource as IList)?.Remove(datagrid.Items[i]);
        //For the case you add Items directly:
        try
        {
            datagrid.Items.Remove(datagrid.Items[i]);
        }
        catch (Exception)
        {
        }
    }
}
datagrid.Items.Refresh();

Don't forget to refresh the grid: datagrid.Items.Refresh()
